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.
USB-C Power Bank – iPhone, Samsung, Nintendo Switch, Steam Deck, MacBook Pro
Find the best USB-C power bank for your iPhone, Samsung Galaxy, Android, Nintendo Switch, MacBook Pro, or other USB-C devices.
Start with the output level (W) for your largest device. Higher output chargers will safely support lower-demand devices.
18-20W USB-C Power Banks
Great for: iPhone, Samsung Galaxy, Android, and iPad Pro (Lightning)
Assume a power bank can only support one fast-charging device at a time unless otherwise noted.
There is only a 1-minute difference in charge time between an 18W and 20W charger for the iPhone 12. If buying for the first time 20W chargers are newer, 18W may be cheaper. If you already have an 18W then a 20W upgrade does almost nothing for you.
Smaller Capacity
Up to 10,000mAh will recharge most phones two or more times over, more than enough for a long day.
Recommendation: ZMI PowerPack 10K USB-C is the best value, especially for non-iPhones which can use the included cable.
Larger Capacity
Enough capacity to support several devices or to keep your phone going for a weekend or more. With more capacity comes more weight and a higher cost.
Recommendation: If you need all the capacity you can get the ROMOSS 30000mAh Power Bank Sense 8 is very popular world wide.
25W USB-C PPS Power Banks
Great for: Samsung Galaxy S20 and newer phones
Assume a power bank can only support one fast-charging device at a time unless otherwise noted.
These chargers support 25W PPS, a lower heat and stress fast charging mode supporting by newer Samsung devices among others. They are considered optimal and help prolong battery life, but an 18-20W charger can get the same job done. Apple devices do not support PPS, so while these chargers would work with an iPhone there is no special benefit to using them.
30W USB-C Power Banks
Great for: Nintendo Switch (handheld), iPad Pro (USB-C), Samsung Galaxy Note, MacBook Air
Assume a power bank can only support one fast-charging device at a time unless otherwise noted.
Recommendation: Slim pickings at this output level. Include 45W power banks in your search as you can find better value there.
45W USB-C Power Banks
Great for: Steam Deck, Samsung Galaxy Note Plus
Good for: MacBook Pro 13-inch, most 13 and 14-inch PC laptops
Assume a power bank can only support one fast-charging device at a time unless otherwise noted.
Recommendation: Anker PowerCore III 19K 45W is a decent value for a few more hours of life. Only go after a more expensive 26,800mAh model if you’re sure you need the extra capacity. Also consider the 60W range for potentially better value.
60W USB-C Power Banks
Great for: MacBook Pro 13-inch, most 13 and 14-inch PC laptops (60W)
Great for: MacBook Pro 15 and 16-inch, most large PC laptops (87-100W)
Assume a power bank can only support one fast-charging device at a time unless otherwise noted.
A USB-C to USB-C cable which supports 100W (5A) power is required to get the full 65-100W on supporting chargers. Otherwise, they act like a 60W charger.
Recommendation: ZMI PowerPack 20K Pro is my pick for the 60W range. The ZMI PowerPack No. 20 Worldwide Edition is your best option if you need maximum power output, or to fast charge 2-3 devices at once.
Qi Wireless Charging
Great for: Wirelessly charging newer iPhones and Androids with MagSafe and/or Qi wireless support
Qi wireless power banks are often larger and heavier, making room for the needed charging coil. Wireless charging is always slower than wired charging using a fast-charging connection. The upshot is the convenience of not having to deal with cables.
Recommendation: ZMI LevPower M10 USB-C is the best value.
USB-C Power Stations
Great for: Laptops and similarly sized devices which use a wall charger, camping/outdoor power source, backup power
Power stations are large power banks offering both more capacity and an AC outlet, with a similar function to a wall electrical outlet. Note they are more limited than a wall outlet, so be sure your device doesn’t draw more watts than a power station can offer. The units below also include USB-C PD as output options.
18W Quick Charge USB-A 12W USB-A
Recommendation: Go with the model that meets your specific power needs. AC output is critical, it must be equal to or less than the demands of the devices you plan to use it with. After that comes capacity, especially if being used as backup power.

Who It’s For
If you spend a lot of time outdoors, this is among your best choices for keeping your devices running while off of the grid. In other words, it’s camping approved.
What Size Battery Do You Need?
On the.friendly front, most smaller batteries have a capacity of around 5,000mAh, which is typically enough to top up most phones once.
Meanwhile, a 10,000mAh battery can give today’s flagships two full charges. A 20,000mAh battery can charge a flagship four times, or two phones two times. Some power banks have enough juice to power laptops. Of course, a higher capacity often translates to a heavier, larger, and more expensive battery.
Most companies advertise how many times their products can recharge popular phones, but if you want to calculate that number for yourself, RAVPower has a useful guide (Opens in a new window) that can give you an estimate.
In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty.
What’s the Difference Between Power Input and Output?
You’ll find three types of ports on today’s portable batteries:
Generally speaking, you charge the battery itself via micro USB or USB-C (input). Some batteries charge faster than others and USB-C charges much faster than micro USB.
Nearly all batteries include a standard USB-A port (output). This is for plugging in USB-A-to-micro-USB, USB-A-to-Lightning, or USB-A-to-USB-C cables for charging your iPhone or Android device.
Some batteries include built-in output cables and these generally have micro USB, USB-C, or Lightning connectors.
The most important thing to do is to match the battery’s output to your phone’s input. For example, if you have an iPhone, be sure the battery has its own Lightning connector or supports USB-A-to-Lightning or USB-C-to-Lightning cables.
Larger batteries with higher capacities might include a multitude of ports to support input and multiple outputs at the same time. You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common.
If you picked up an iPhone 13 or iPhone 14 and were surprised by the lack of an included wall charger, see our article on charging your iPhone.
What Is Fast Charging?
Another factor to consider is how quickly a power bank can charge your device. Battery output is measured in voltage and amperage. Amperage (or current) is the amount of electricity that flows from the battery to the connected device, while voltage is the amount of potential energy. Multiplying volts by amps gives you wattage, the measure of total power. To make devices charge faster, most manufacturers either vary the voltage or boost the amperage.
Today’s devices support a wide range of Rapid-charging technology, such as Qualcomm QuickCharge, USB Power Delivery, or proprietary fast-charge systems.
Quick Charge works by increasing voltage rather than amperage. This standard typically allows you to charge supported phones to 50 percent capacity in 30 minutes, which is especially helpful when you need power in a pinch.
Power Delivery is a newer protocol in which two compatible devices negotiate on the fastest charging option available based on the charger, cable, and circuitry. It also allows for power to flow both ways.
The most common devices (Apple iPhones and Samsung Galaxies) support charging rates of 27W and 45W, respectively. It’s best to look for batteries that can support charging in that range.
Is Pass-Through Charging Safe and Useful?
Pass-through charging is another feature to consider; with it, you can charge devices and the portable power bank simultaneously. That’s convenient if both your phone and backup battery are running on empty. You shouldn’t encounter any safety issues if the manufacturer of the portable battery you buy advertises pass-through charging as a feature, but the power output might change in this mode.
How Does Wireless Charging Work?
Wireless charging has become popular because it allows you to power up compatible devices without a cable. Qi is the dominant standard for compatible Android phones (up to 18W) while Apple iPhones rely on MagSafe charging (up to 15W). iPhones will charge wirelessly on Qi chargers, but only at 7.5W.
Some battery makers have built Qi or MagSafe-compatible wireless charging into the surfaces of their portable batteries. Such batteries mean you can leave the cables at home.
Should You Buy a Battery Case Instead of a Power Bank?
If you find that you often forget to carry your backup battery when you need it most, you should consider a dedicated battery case instead. These combine the portability and protection of a case with additional battery capacity to keep your phone topped off at all times.
There are several drawbacks. First, they have limited additional capacity on board. Second, they are limited in terms of the number of phones they support (mostly just iPhones, Galaxies, and Pixels). Third, you can’t charge much else with them.
The Best Wireless Chargers
Why fumble around for a charging cable when you can rest your phone on a wireless charging pad? Whether you’re an Android user or an iPhone fan, check out our roundups of the best wireless chargers and the best MagSafe chargers to help you cut the cord.

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.

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.
