Powerful

Great power bank, I had one before but lost on my holiday. This is 5G epoch, we using internet mobile phone all the time, I will definitely recommend, people get power bank one for each. Much convenient if you go out don’t have to worry about battery run out. Light weight to put on the This power bank 20000, battery life is ok, use on my iPhone change about 3 times. About 3-5 mins turn on when phones switch off. Very powerful.

Good quality charging treasure

The quality of the charging treasure is very good, easy to use, the size is also very suitable, the charging is also very fast, the appearance is also very beautiful.

Super love!

It works very well. I like it very much. It can be flushed several times. And the remaining electricity display is very convenient to know! It’s just the right size.

A powerful power bank

A large capacity power bank (20000mAh). Very portable design, and good for many recharges of my devices (mobile, tablet, mouse, Bluetooth headphones, etc.) I always carry it in my bag now :P. What made me opt for this one has been mainly that it has a fast charge (and indicates the %), multiple protections (overcharge, short circuit, over-discharge. ) and is compatible with USB Type C. Remember that it takes a few times to charge due to its high capacity.

Big power small price

Needed a power bank for work as I travel to ensure my phones are charged and I’m never out of juice. This charge up quickly both the power bank and the devices attached to it. The led display showing battery life is very helpful for knowing when it needs a charge. It’s a little heavier than I expected but it does hold slot of juice so Can’t really complain. If you want a big capacity and small price device then go for this you won’t regret it.

Ideal for travelling

If you have the need for a portable power bank, I can highly recommend this one. About the size of a mobile phone, but a little heavier, it can recharge your own mobile or tablet several times before needing to be recharged itself. The actual power remaining in the bank is shown as a percentage display, so you know if it is running low itself. I carry this around with me to keep my phone and tablet on the go all the time and it is excellent for doing this. Well-made item, very pleased with it.

decent power bank

USB-C port can be used as either input or output alternative micro-USB input port displays power bank battery %. one USB-A output port

Quick charger. nice feel

Does exactly what it was intended for. Really nice feel to this, curved/rounded edges makes it easy to hold. The two sides are textured slightly different. one side smooth and one side a really fine crosshatch type of texture. Connections for USB-A, Micro USB and Type C. Nice easy to read digital display. Charge up relatively quick and charges your phone etc very quickly. The packaging is fine and delivery was next day with Prime.

GOOD

This item arrived safe and well packaged. The power bank well wrapped up snug in its box. There was also a mini USB lead included too. this is designed to be used to charge up this device, although it could also be used to charge a device from the power bank if this is the connector needed by your device. I used my own USB C cable to connect the device to my phone (Samsung Note 8). It charged this device with no problem at all, in fact, it’s charged my phone several days in a row now and still has juice left!! This power bank had a HUGE capacity! The device looks great in satin black. very high quality. It’s incredibly easy to use, although an instruction leaflet is included for anyone that needs additional support. I highly recommend this item.

Excellent power bank

It’s more lightweight than you’d expect it to be. My favourite part about this power bank is how it displays the exact capacity instead of using 4 indicator lights as most other power banks would. It lasts very long and is reasonably priced.

A power bank for superheroes

Came in very sturdy and impressive packaging. Bought with an iPhone 8 in mind and this solid feeling device provides quick and effective long-lasting charges, making it ideal to take away for work or on vacation.

A-Class Li-polymer Battery cells.

Nice digital LED display, it tells you the exact amount of power left in increments of 1%. It is capable of charging my device two times faster, than others power banks. It only takes 6-7 hours to recharge the power bank. Lovely smooth and soft matte texture.

Good. Will recommend

Slightly heavier than expected, but charges fast and I really like the display of the power percentage remaining. I have charged my phone couple of times and the power is still remaining, so I don’t know how long it takes to charge the bank.

Shows remaining power, good for travelling

It charges my phone quite quickly. It’s not heavy, and I like it being very convenient that it shows the remaining power it has, not like my other one, I never know how much power it has left. It’s portable too. Good for travelling.

Powerful and good

I’ve bought this charger as it looks small enough to fit to my bag. The charger has a capacity of 20000 mAh, which is more than I expected for such a size. You can charge your phone up to 5 times. It shows the % of power left in it. it’s easy to manage. It’s lightweight and very good quality. Charging is very fast. Smart design. Happy with it.

Powerful and fast charging power bank

Great and reliable power bank that ensures my phone is always fully charged and is there when I need it. It charges my phone much faster than other power banks and it also charges really quickly. I can use it for charging other devices like my wireless earbuds and other mobile phones which is very useful when on the go. Sensor display shows the charging level left which is extremely useful too.

Quick charge

One more power bank in our household. It is times now when you can’t live without phone which is a shame, as I remember myself when we didn’t have them and we still could meet without any problems. Now I need power bank in every bag just in case as my phone and kids phones are more than 2 years old and the battery is not new anymore. This one I really like, it’s slim, but still great capacity, not too heavy to carry around, charges itself and give charge quick.

MUCH better build quality than expected

I’ve needed one of these for ages, phone and pad quite often go flat during a busy day. Very impressed with the build quality. USB-C and USB-micro ports have a very positive feel about them too. It can be recharged quickly by either cable. Charged my phones very fast. Holds more than enough power to keep me fully charged for days. it’s what I need to take on for a holiday. I will never worry it will run out the battery. GREAT PRODUCT.

Fantastic product

I am so amazed at how well this works with my iPad Pro. Charges it fairly quickly. I have not tried it on my iPhone X yet but I am sure it will charge just as well. It did take a long while to charge itself at first and I will admit was a little concerned. But it worked out great and the percentages battery charge light is such a bonus.

Charges up to 5 times before needs charging

Fantastic portable battery charger, incredibly powerful, sturdy and well built. Purchased after a recommendation from a friend who hailed it as the best portable charger he had ever used. One charge of the power bank charges my iPhone 5s five times to 100% before I need to charge the power bank again. The power bank only takes up to 7 hours to charge from near flat. The size is quite slim and not too big for travelling around with, body looks stylish and 20000 mAh capacity is large and speed wise its quite fast too. It’s good value for money and would recommend this to someone who travel often too.

Brilliant battery life.

I have gone for a weekend away in Europe and for 4 days have been charging my phone and earphones of it, came back with 30 percent battery. Brilliant battery life. I really like how it shows the percentage of the battery left. Really happy with my purchase.

Great power bank!

Would give 5 stars for this battery being all you need to keep the phone charged for quite a few days! 10% of this battery has charged my phone (turned off) to 100%! Because it does show the percentage of power left it is easy to know when it’s running low. It is also quite lightweight which makes it a great asset to the trips away! Very happy with this purchase.

Very small!

The build quality of the power bank is superior to many other power banks I have owned. The power bank has color tone of smooth black. Adding to this giving the power bank a slick look. These make the power bank feel very high-end. The black trim on top and bottom of the power bank also adds to the premium feel. There are LED display indicating the remaining charge in the power bank. The two USB ports for output to charge devices and the input micro USB port for charging the power bank are all on the same side of the power bank. The power bank has a capacity of 20000 mAh, which should easily charge your device multiple times from 0% to 100%, for a Galaxy S6 edge it should charge it approximately 4-5 times before the power bank needs recharging.

No, it cannot. This power bank supports to charge 2 devices at the same time, BUT do not support charge your device and be recharged at the same time.

It comes with a USB charging cable.

From our testing data, it will take about 6-7 hours. And please note that the recharging time will be varied from the different input voltage and current.

Yes, it can. This power bank can charge most of your mobile devices, including smartphones, Bluetooth speakers headphones, digital cameras, Smart wearables and more.

It can charge about 4 times for your Samsung S9.

This power bank does have a USB-C port, but we do not recommend using this power bank to charge your MacBook series because it only equipped with up to 15W power that is not suitable for your high-power devices.

No, it does not. But it can provide up to 5V/3A fast charging speed.

Yes, you can. The USB-C port support output and input function.

We do not recommend to do like this, because when you leave any battery constantly charging like that you will reduce the lifespan of the chemicals in the battery that make it function.

Sorry, this power bank does not support pass-through charging.

No, it can not charge any MacBook series.

Yes, the power bank support dual input at the same time, but with a max input of 5V/3A.

Yes, we recommend you charge it fully to 100% in the first time using.

Yes, it can be taken on a plane.

Now, you might not think that you need a display on a power bank, but in practice, it comes in very handy. It’ll tell you the output on each port, the remaining charge, and how long it’ll last at the current charge rate.

Sure, it’s expensive, but considering the specifications, it’s a fairly reasonable asking price. If you’re looking to juice up one of the latest super-fast charging smartphones at full speed, this is the tool for the job.

Shargeek Storm2 Slim

If you want a power bank that makes a statement, this is the one for you.

  • The coolest-looking power bank ever
  • Incredibly detailed display and menus
  • 100W output and 20,000 mAh capacity

Quite simply, this is the most impressive-looking power bank we’ve ever come across. It has a semi-transparent chassis that allows you to look at the components inside, along with a colour display that’ll reveal all the technical details.

It’s a wonderfully geeky design, that lands somewhere between a cyberpunk aesthetic and early 2000’s nostalgia. We absolutely love it.

If you thought having a display on your power bank was overkill, strap in, because the Shargeek takes things to the next level. There’s a full menu system on this thing, allowing you to check out individual cell voltages, temperatures and more. You can even set timers to avoid wasting your charge.

Of course, none of this matters if it’s not a solid power bank, and thankfully it very much is. With a 20,000 mAh capacity and the ability to deliver 100W fast charging over USB-C, it’s ready for anything. You’ll have to be prepared to fork out some cash, though.

Excitrus 105W Power Bank Ultimate

Serious power and portability, combined with unassuming looks. This could be the sweet spot for a lot of people.

pb20, 20000mah, portable, power, bank

This option from Excitrus has a much more subtle design, and if you didn’t know better, you could easily mistake it for any other run-of-the-mill power bank.

On the inside, though, it’s extremely capable. It can deliver 87W from its USB-C port, while simultaneously outputting 18W over USB-A.

That’s enough power to charge a Surface Laptop 4 and a Google Pixel 6 at full speed simultaneously.

What’s more, it’s very compact and lightweight for its specification, along with being reasonably priced.

Anker 325

If you’re not overly concerned with fast charging, this option offers loads of capacity and excellent build quality at a bargain price.

It comes at a very affordable price but still benefits from Anker’s excellent build quality and renowned reliability.

The massive 20,000 mAh capacity is enough to charge an iPhone over four times, so it’ll keep you going for a really long time.

It’s also very slim and lightweight, for its capacity, so it won’t weigh you down too much when you’re out and about.

Tecknet 10k

Amazingly cheap and reasonably quick, this one gets things done without breaking the bank.

If you’re after something cheap and cheerful, we’ve had great results with this option from Tecknet.

It’s not the largest capacity, nor does it have the most impressive speeds, but it comes at a bargain price. and it’s still a touch speedier than the Anker 325.

The 20W output is fast enough to charge phones like the iPhone 12 and Google Pixel 6 at full speed. So if you’re using a basic power bank, you’ll see a definite jump in charging times with this product.

It’s super thin and lightweight and can be charged via USB-C or Micro USB, so it’s easy to top up when the time comes.

How to choose a portable charger

Choosing a portable charger can feel like a monumental task, there are just so many to choose from. With such a variety of sizes, capacities, styles and specifications on the market, it’s especially hard to find the right one for you.

To help narrow down your choices, here are a couple of things we recommend thinking about before you commit to a power bank.

pb20, 20000mah, portable, power, bank

How much capacity do you really need?

It can be tempting to go for the largest capacity available; the more juice the better, right? Well, these high-capacity chargers also tend to be heavy and bulky, so they can be a bit of a pain to carry around with you. We recommend taking a moment to think about the situations you face that normally call for a power bank. If you’re camping out in the wilderness for days on end, then a giant capacity charger may be just what you need. but if you’re just trying to get an extra bit of battery life to see you through your commute, you’d likely be happier with a slimmer and more lightweight solution.

What do you need to charge?

While pretty much any power bank will charge your phone, laptops, in particular, are where things get more complicated. Most USB-C-powered laptops will require a high-wattage USB-C Power Delivery (PD) specification. It all depends on the laptop model, but generally speaking, for laptops, you’re likely to want 60W PD spec or above, especially if you want to charge the laptop while it is in use. Check your model’s specifications to ensure you get a power bank that’s up to the task.

If you’ll only be charging phones or tablets, then any charger will work, but be aware that not all are created equal. If you want to take advantage of fast charging then it’s worth paying attention to the specs to ensure that your device will be compatible. Samsung phones seem to be especially picky when it comes to fast charging, but so long as you cross-reference your manufacturer’s charging specifications with the power bank’s specifications, it shouldn’t be too hard to figure out.

How to Choose the Right Power Bank?

For a longer trip, you may want to choose a power bank with a higher mAh and wattage. Power banks with higher mAh can last for more charge cycles before needing a recharge themselves. This is especially helpful for trips that have a long travel time where you may not have guaranteed access to wall outlets to power your devices.

We recommend anywhere from 20,000 mAh to 30,000 mAh and 65W to 100W for trips with extended travel time. This level of charging capacity helps give you peace of mind during travel (which is already stressful as it is) and guarantees that you will not have to rely on wall sockets for your devices or for a recharge to your power bank.

For a shorter trip, you may not need as much mAh and wattage in your power bank. We recommend a range of 6000 mAh to 10,000 mAh and 20W to 45W for trips with a shorter travel time. These types of power banks hold plenty of energy to guarantee 1 or 2 full charges to your smartphone without needing to be recharged. That should be plenty of power to get you to your destination and within reach of a wall outlet.

Devices are particularly important during business trips. You may need your phone to link up with colleagues and your computer to get tasks done. For that reason, you may want to choose a power bank that has a high mAh to last multiple charging cycles, and that can power a variety of devices.

We once again recommend a 20,000 mAh to 30,000 mAh and 65W to 100W power bank for business trips. It may also be useful in these cases to have multiple power banks dedicated to each of your devices. Our Baseus Blade Laptop Power Bank has a charging capacity of 20,000 mAh and 100W, making it an excellent source of energy for your laptop while your phone is linked up to another portable charger.

When it comes to parties and small day trips, you will not need a portable charger with a huge charging capacity. We once again recommend a range of 6000 mAh to 10,000 mAh and 20W to 45W. Our Baseus Magnetic Foldable Power Bank, with a 10,000 mAh and 20W capacity, is particularly convenient for parties and other outings thanks to its ability to fold up and be used as a kickstand. Easily stored in your. it utilizes a magnetic connection to secure strongly to your device, providing a fast charge without interrupting your device usage.

All You Need to Know About Power Bank

Power banks allow you to charge your devices on the go. With a power bank in hand, you can juice up and continue to use your devices without worrying whether or not there will be outlets nearby to keep you going.

Power banks, also known as portable chargers, operate in a similar fashion to your bank account, hence their name. They act as a storage facility for energy. You can use the electrical energy stored within your power bank to charge your devices anytime and anywhere. This is largely thanks to a special type of circuit contained within the power bank itself that controls the flow of energy.

The process is really quite simple and consists of 3 parts: energy absorption, energy storage, and energy release.

Before you head out on any excursion, whether it’s a business trip, a day out with friends, or any other instance where you may find yourself without ready access to outlets, charge up your power bank through an external power supply like a wall socket. The energy will be stored within the portable charger in a chemical form, ready to be passed into your device at any moment when it is connected to the charger via an output port.

A fast charging power bank is exactly what its name implies: a portable charger that can juice up your devices at a much faster rate than simple wall chargers. These power banks utilize a higher voltage and essentially increase the number of watts being pumped into your device to charge it up more quickly than average.

Wireless power banks are extremely convenient for those who hate traveling around with tons of wires. Rather than getting all tangled up in wires every time you need to charge your devices, simply rely on a wireless power bank. Though they do require a USB to charge themselves, these handy gadgets have the ability to charge your devices through contact alone, with no wired connection required. Battery cases that attach to the back of your phone are one common example of wireless power banks.

To understand the question, we first need to take a look at mAh. The unit mAh is also known as a milliamp hour, and it refers to the charging capacity of a power bank. It indicates how much energy can be transferred from your power bank to another device over time. And, of course, the higher the mAh of a power bank, the more energy it can provide.

Today’s average smartphone has a battery capacity of 2,800 mAh. With that number in mind, let’s break down the charging output you can expect from these common types of power banks:

  • 6000 mAh: 2 full smartphone charges before power bank recharge required.
  • 10,000 mAh: About 3.5 smartphone charges before a power bank recharge is required.
  • 20,000 mAh: 7 full smartphone charges before power bank recharge is required.
  • 30,000 mAh: Nearly 11 full smartphone charges before a power bank recharge is required.

The lifespan of a power bank may vary depending on various factors, such as quality, build, battery capacity, type of battery, and how the power bank is used. The average lifespan range for a power bank may be anywhere from 1.5 to 3 years or 300 to 1000 charge cycles. It’s important to remember that charge cycles are likely the most accurate representation of lifespan. This is because some may use a power bank more frequently than others, making years an inaccurate depiction of the lifespan that does not factor in usage.

To increase the lifespan of your power bank, remember to take good care of it. Here are a few useful tips to help you make the most out of your portable chargers:

  • Do not use a power bank to charge your devices above 80%.
  • Do not leave power banks in extremely hot or cold temperatures.
  • Do not let your power bank reach 0%.
  • Do not bring your power bank in contact with liquids of any kind.

With power banks and other types of batteries, the first thing you need to worry about in terms of wattage is the watt-hour. Watt-hours indicate how much energy you can get out of a battery and the rate at which that energy will be transmitted from the power bank to your device.

The second thing to worry about when it comes to wattage in your power bank is the overall energy capacity. Oftentimes, the wattage of a power bank refers to its maximum charging output. This may be higher or lower depending on how the power bank is being used. When used as a means of gaining energy from an external source, the maximum wattage output may be higher than when it is used as a power bank on its own. So, if you used a dual 45W power bank, you might expect the energy output to reach up to 45W when used as a charging station from an external source and up to 30W when used as a standalone power bank.

If you’re wondering how to charge your power bank, we’re here to help you there too. To juice up your portable charger, simply connect it to an external power source like a wall socket, just like you would with your devices. This will allow it to absorb and subsequently store electrical energy to then be transferred to your device of choice later on when needed.

The best power banks 2022

Choosing a power bank can be a minefield. There are cheap ones, pricey ones, and sometimes you’re paying simply for a name – but there’s a lot more to finding the perfect portable charger than looking at price alone.

Some other things you might consider include speed, both in charging your connected device and recharging the bank when it empties. Capacity is important, too: it needs to be high enough to get your through the day with juice to spare – even share – without weighing down your or bag.

Ports and connections matter, too. What are you charging? A phone, a laptop, a watch? The number and range of ports is important, and if you want to avoid carrying multiple cables then you could look for a version with built-in cables or wireless charging.

While we care about design, it’s actually much lower on our priority list than the things we mention above – unless, of course, we have need for a particularly rugged model or something that supports solar charging because we’re going to be away from mains power for an extended period. That’s not to say we won’t appreciate added extras such as an LCD screen and waterproofing – don’t you want the coolest and most convenient power bank you can get for your money?

These days, it’s even possible to rent power banks as and when you need them (check out ChargedUp). Mind blown. To ensure you get the very best power bank for your needs, whatever that looks like, read on for more detailed buying advice below our chart.

Best power bank reviews

Zendure SuperMini X3 – Best 10000mAh Power Bank

The Zendure SuperMini X3 certainly isn’t the cheapest 10000mAh power bank around, but it makes up for that in specs.

The headline is the 45W USB-C PD charging – for both input and output. That means you can re-charge the power bank itself in just an hour or so, but also that this is fast enough to meet the max charging speeds on most Apple and Samsung phones, and can even keep many laptops running.

The same port also supports the PPS standard at up to 33W speeds.

There are also two USB-A ports, one at 18W and another at 15W, and you can use all three ports simultaneously with 15W speeds from each.

Throw in the small LCD display to report battery life and the light and compact design (in a range of four colours, no less) and it’s easy to see why you might want to spend a little extra for the SuperMini X3.

Charmast 10,400mAh Power Bank – Best Value Power Bank with LCD

There was a time when power banks with LCD displays were rather expensive, but have now come down as the screens filter through to even affordable models like this.

The power bank also has three outputs, which will come in handy if you have multiple devices to charge. There are two full-size USBs, plus a USB-C PD port that can act as both input and output, and all three support 18W Quick Charge – although only one at a time.

On the side is an additional Quick Charge 2.0-compatible Micro-USB, which can also be used for charging the bank. It will charge in about 3.5 hours with a Quick Charge/PD adapter, but about 5.5 hours with a standard 10W charger.

The downside of the design is that it’s a bit bigger than many of the super-slim, similar-capacity models on the market. This Charmast is roughly the same width as a phone, but a little shorter and a fair bit chunkier. It weighs in at 228g, which you may decide is better suited to a bag than your

Charmast supplies a soft mesh carry case and a short USB-A to USB-C cable in the box, a nice touch.

Zendure SuperMini Go

  • Interesting camera-inspired design
  • Supports 15W wireless charging
  • Strong device support
  • Available only via IndieGoGo (for now)
  • LCD is a little dim and can be difficult to read

The Zendure SuperMini Go is something a little different: a power bank that tries very hard not to look like one.

Zendure’s design is inspired by classic cameras, which is if nothing else a fun way to incorporate the large ring required for wireless charging – which here sits right where a camera lens would be. Instead of a viewfinder, there’s a rear LCD display to show battery percentage – though be warned that this is quite dim and hard to read.

It’s available in silver and black finishes, along with our more out there ‘Sunset Cyan’ gradient.

The SuperMini Go isn’t all about looks though, and it has some solid specs to match. The total capacity is 10,000mAh, and in addition to 15W wireless charging (with a magnet to keep phones steady) there’s 20W USB-C charging and 22.5W USB-A charging.

Compatibility is impressive too – not only will this work with both iOS and Android devices, but the ‘X-Charge’ mode is capable of topping up lower power devices like wearables and headphones, which not all power banks support.

The SuperMini Go is available now for backers on IndieGoGo with discounted launch pricing from 44 (down from an official price of 69), but with Zendure’s track record it’s very likely this will be in stores including Amazon before long.

JIGA 30,000mAh Power Bank – Most Versatile Power Bank

JIGA is a new name to us in terms of power bank tech, but its 30,000mAh power bank is interesting for a number of reasons – and not least the huge capacity, which will be some comfort on trips away from mains power.

While it’s something of a throwback to power banks from a couple of years back, with its built-in LED flash (certainly useful for camping trips) and durable but plasticky design, it also takes us back to the days where you didn’t have to sacrifice ports for portability.

It’s surprisingly small for such a high-capacity bank, but it’s more bag- rather than.friendly.

The JIGA has USB-C, Micro-USB and Lightning inputs, allowing you to fill its battery using whatever cable you have to hand. It’s a shame that the USB-C port doesn’t also work as an output, but there are three full-size USB-A outputs, each rated at 10.5W.

This isn’t the Power Delivery speeds we’re becoming increasingly familiar with today, but it’s plenty fast for charging a phone (or multiple phones).

If all you need is a healthy stream of power to keep topped up a number of mobile devices, this JIGA power bank will be a very handy device to have around.

Anker PowerCore Essential 20,000 PD – Best 20,000mAh Power Bank

Hailing from Anker, a respected brand in the power bank market, this 20,000mAh portable charger represents very good value at this capacity.

The 345.5G Essential is a black plastic brick, though relatively compact for the amount of power it can hold. It has a textured top surface that improves grip in the hand, as well as the overall appearance.

We’re pleased to find support for Power Delivery, but do note that it’s only up to 18W, and therefore not likely to be sufficient to charge a USB-C laptop. Still, for quick-charging a phone or tablet, this is a useful device.

A full-size USB output that uses Anker’s PowerIQ smarter charging algorithm is joined by a USB-C port that is both input and output. On top is a power button with four integrated LEDs that reveal remaining capacity, and you can use this to enter a trickle-charging mode suitable for smartwatches and earbuds.

A USB-C to USB-C cable and soft mesh carry case are provided in the box, which is a nice touch.

Anker PowerCore III 10K Wireless – Best Wireless Power Bank

The Anker PowerCore III 10K Wireless is a Qi wireless charger with a special feature: you can use it as a portable power bank, too, which can be super handy.

You can use it at home or work plugged in, and carry it around with you for wired or wireless charging when you are away from a power socket. Because it’s wireless, there’s no need to carry a cable around with you.

As the name suggests, the PowerCore III 10K has a decent sized 10,000mAh battery, which should offer at least three charges from the power bank before it needs recharging itself.

The wireless charger is rated at 10W. Place your device on the centre of the circle. We didn’t find the placement too sensitive, as some wireless chargers can be. It’s not auto-start, though – as a power bank it requires you to push the button first.

You can also charge from the two USB-A ports at one end – at a total of 18W, so charging two or three (one wireless, two wired) devices will split that power output.

Anker PowerCore Magnetic 5K – Best MagSafe Power Bank

This portable wireless charger is one of the best accessories you can get for your iPhone.

In essence, it’s a 5,000mAh palm-sized power bank that will charge your compatible iPhone simply by snapping it onto the back with MagSafe.

It works through some cases, charges over USB-C, comes in a range of colours and, even if you don’t have MagSafe, can be used to charge almost anything via cable.

A handy set of LEDs indicates how much charge the PowerCore has remaining.

Moshi IonGo 5K Duo – Best Design

It’s expensive, but you’ll pay out for the IonGo 5K Duo from Moshi if style is as important to you as is functionality.

Almost identical in design to the IonGo 5K before it, but here with both USB-C and Lightning cables built-in (hence the name Duo), the Moshi is an undeniably cool-looking power bank that comes tucked away inside a vegan-friendly soft leather case with a magnetic clasp and an anodised aluminium faceplate.

The additional cable means it’s now suited to Android as well as iPhone users, although as before this is Made For iPhone-certified.

This is a truly premium device with a colossal 10-year warranty going a long way to account for its higher asking price. It’s also possibly the dinkiest 5,000mAh power bank we’ve seen, suggesting there are some serious high-tech components inside.

At this capacity, expect a full charge for any Android phone, and potentially two for iPhone. Moshi claims the bank will also retain that power for up to 27 months when left unused.

Charging is up to 15W over USB-C and 12W over Lightning. Use Lightning and USB-C together and you’ll see slightly slower charging speeds, with a max total output of 3.4A (17W).

You can also use the USB-C cable for recharging the bank, again up to 15W. Better still, the Moshi supports passthrough charging, allowing you to charge both it and a connected device at once, but given that there’s no separate input here that’s going to work only with iPhone.

The Duo is currently out of stock at Amazon, but you can still pick up the iPhone model.

Chargeasap Flash Pro / Flash Pro Plus – Fastest Charging Power Bank

  • Unbeatable recharging speed
  • High-capacity (25,000mAh)
  • Range of outputs
  • 5-year lifespan
  • Expensive
  • Bulky and heavy
  • Attracts fingerprints
  • No charger or cable supplied

These graphene-composite power banks are able to charge cooler than ordinary lithium-polymer batteries, and thus can do significantly faster: you’ll get to 80% of these 25,000mAh batteries in just 45 minutes.

In addition to this there is a healthy smattering of ports, with three USB-Cs running at 100W, 60W and 20W, a 50W USB-A that supports Quick Charge 3.0 and SVOOC, plus wireless charging. You get a 15W MagSafe pad and a 5W Apple Watch charger in the Flash Pro Plus, and a 15W Qi charger in the Flash Pro.

Down sides include an expensive price tag, and a bulky, heavy design, but for sheer performance and functionality the Chargeasap banks are among the most capable we’ve ever tested.

FAQ

What capacity power bank do I need?

Don’t fall into the trap of thinking a 3,000mAh power bank will give your 3,000mAh battery smartphone a full charge, and that a 9,000mAh power bank will charge it three times. No portable charger runs at 100% efficiency. In truth, most average between 60- and 70%, with the best-performing models able to reach 80- or 90%. Wireless charging models may be less efficient still.

To work out what capacity bank you need, first check the spec of the device you want to charge to find out its battery capacity, then decide how many times you want to be able to charge it. For a rough estimate, calculate Connected device battery capacity x Number of recharges x 1.6 = Minimum power bank capacity you should look to buy.

As a rule of thumb, a 5,000mAh bank is a single-charge device, 10,000mAh hits the sweet spot between capacity and portability, and you want to look for closer to 20,000mAh for a laptop. We’ve got some of those high-capacity power banks here – just don’t try to stuff any of them in your !

How long does it take to recharge a power bank?

The time required to recharge a power bank will depend on its capacity, what you are using to recharge its battery and whether or not it’s empty.

For the fastest charging you should look to the new breed of power banks that support graphene technology and charge over a DC input (such as the Chargeasap Flash Pro – a 25,000mAh bank that can get to 80% in 45 mins and 100% in 70 mins), but these tend to be pricey.

For mainstream power banks, the fastest you’ll find is a USB-C inout/output that supports Power Delivery. This standard now goes up to a maximum of 240W, but in portable chargers you should expect to find an 18W port. Using such a port, the average 10,000mAh power bank might recharge in 2-3 hours from empty.

The cheapest models still tend to charge over Micro-USB, usually at around 10-12W. Avoid 5W power banks like the plague unless they are very low in capacity or you’re not in a rush.

What is passthrough charging?

Passthrough charging allows you to simultaneously charge devices connected to a power bank and the power bank itself. It’s a very handy solution if you are short on mains power outlets and need to get multiple devices charged up overnight, for example. However, not all power banks support it, so be sure to check the spec of your portable charger before you buy.

How do I know how much power is left in my power bank?

Assuming you know how much capacity it had when full, you can work out how much power remains either through a series of LEDs on the casing (usually activated by plugging in a device to charge or pressing a button on the side), or via the LCD if your power bank supports one. LCDs are preferrable, because they give a more accurate readout, particularly when it comes to higher-capacity power banks.

What are GaN power banks?

GaN is short for gallium nitride. It requires fewer components than traditional silicone chargers, which means power banks that use the technology can be less bulky and more efficient. If portability is your primary concern, then as well as considering the power bank’s capacity you should also look for one that uses GaN.

What charging speed should I look for in a power bank?

The first power banks on to the market ran at 5W, which is the same speed as the original iPhone chargers (aka slllllloooooowwwww). We wouldn’t recommend anything below 10W these days. This speed is known as ‘fast charging’, and it’s still rather common in cheaper models, but it’s not really the fast charging we’ve become accustomed to today. So many of the latest smartphones now support super-fast wired charging, and it seems crazy not to buy a portable charger that supports that top speed if possible.

The standard your phone uses to achieve its top charging speeds is important here. Some have proprietary technologies that work only with accessories manufactured and sold by that company. Some offer fast charging through Quick Charge or Power Delivery. Some support neither Quick Charge nor Power Delivery, but do support protocols such as PPS (Programmable Power Supply) or SCP (Super Charge Protocol). Make sure the portable charger you buy matches the fast charging standard supported by your phone.

The term Power Delivery does not in itself denote a performance rating. It could be capable of delivering anything between 18W and 240W. This is particularly important if you’re looking to charge a USB-C laptop – anything under 30W won’t cut it, many laptops will refuse to play ball below 45W or even 60W, and some larger laptops might require 90W. You will need to check the spec of your laptop to know what speed it requires.

At the other end of the scale, if you need to charge a low-power device such as a smartwatch or a pair of wireless earbuds, look out for a power bank that is certified for low-power devices. Many of those that are not will simply cut out when you try to charge these devices, because they aren’t able to detect a significant drain on the battery.

Power bank manufacturers rarely provide the speed of their outputs in watts. Instead you’ll see a rating in amps, which you multiply by the voltage rating (usually five) to get the rating in watts. So 2A x 5V = 10W.

What is Power Delivery?

USB-C and USB PD are often confused, but the important thing to remember is that USB-C is a reversible connection type, while USB PD is a power delivery specification, overseen by the USB Implementers Forum (USB-IF) and often expressed simply as ‘PD’. With version 3.1 of the specification, Power Delivery is able to carry up to 240W of power plus data over USB-C (previously limited to 100W), but devices that support Power Delivery can range from 18W right up to 240W.

What is Quick Charge?

Quick Charge is a Qualcomm fast-charging protocol that runs on the Snapdragon processors we see inside many smartphones, hence it has become commonplace in the mobile market.

The latest version is Quick Charge 5, which operates at up to 100W and supports USB PD PPS. However, while they are often seen together, Quick Charge and Power Delivery are not the same thing.

Quick Charge 5 is a massive jump up from Quick Charge 4/4, more efficient and able to run cooler and safer, and Qualcomm says it can get a device to 50% in just 5 mins. It is backwards-compatible with earlier versions of the protocol, including 18W Quick Charge 2/3, which are still very common in power banks.

Which outputs should I look for in a power bank?

The type and number of outputs you will need on a power bank depends entirely on what device or devices you want to charge. Pretty much all power banks have a full-size USB output that you can use to plug in your own cable, but it’s not always going to be the fastest way to deliver a charge to your device. You’ll also find USB-C and Lightning outputs, magnetic wireless charging pads and AC outlets if you shop around. Some power banks even have built-in cables to stop you needing to carry around your own, though you will still need one handy to recharge the power bank itself.

Why is the maximum output of a power bank important?

Some power banks have multiple outputs for charging your connected devices, but few power banks are able to simultaneously support all of them at the top advertised speed. Watch out for those that have a lower maximum output than the sum of all ports together. Also be wary of those that have multiple outputs but a very low capacity – these aren’t really designed for plugging in multiple devices, only to be versatile.

What happens when my power bank is more powerful than my connected device?

There is no need to worry about plugging devices into ports that are capable of delivering more power than the device is able to accept, since USB devices will draw only the power they need. Many power banks include technology that is able to intelligently dole out this power among ports more appropriately, depending on what devices you are attempting to charge (often known as Power IQ or similar).

Can I take a power bank on a plane?

Yes, but it must be in your hand luggage, and if it is higher in capacity than 27,000mAh (100Wh) you will need to check with the airline before flying. Make sure you take it out your bag as you pass through security. If a power bank is damaged then it will not be allowed on the plane as it could become a safety hazard. You should also ensure the specifications are clearly printed on the side of its case, as is the norm.
