Things You Need to Know Before Buying A Power Bank

Back in 2001, the prototype of a power bank appeared in CES. Since then, the power bank market has grown phenomenally and today, you can find hundreds of different brands on the market. There are so many to choose from, with capacities ranging from 500mAh to 30,000mAh, single or multiple USB ports, with or without a flashlight, etc. Earlier this year, several mobile phone manufacturers including Xiaomi, Samsung and Nokia launched their wireless power banks, making the market even more competitive.

The choice is bewildering, and it’s not like you can just ‘fish a power bank out of the sea’. Yes ok, there are lots of tips and guides out there, but today we are going to see how the tech gurus make their choice. You might even get a fringe benefit.

What Does A Quality Power Bank Look Like?

The easiest and quickest way to judge the quality of a power bank is to check the quality of its case. What materials are used? How well is it designed? Are there any signs of damage? Is the button easy to press?

A quality power bank should have:

1) A clean and complete surface, nothing out of shape. There should be no signs of mechanical damage, no corrosion on any of the connectors.

2) Clear markings about the power ratings, avoid anything blurry that you cannot read.

3) Make sure any buttons and lights work correctly.

It Should Have These Numbers

Every power bank should have markings which clearly state what the power ratings are. That will help you to understand if it can properly charge your phone or not.

1) The basic information should be illustrated on the product or in the user manual; this usually includes the capacity, model number, product type, manufacturers’ information, etc.

2) The Rated input voltage/current and the output voltage/current information is fundamental. But what do these numbers mean? The rated input tells you the standard voltage that the power adapter can connect to so that it can charge the power bank.

If you lose the original power adapter, you could buy a third party one that matches instead of the original. The rated output has to match with the output voltage of the original power adapter for your phone. It’s not recommended to charge your phone with a power bank that has different voltages; otherwise, you may well damage your phone.

3) How many times can the full power bank charge my phone? That’s the question a lot of you will want to know. Usually, that sort of information is not written on the power bank, but with rated capacity and cell/battery rated energy, you can do the math yourself. Don’t worry. We will get to that later.

4) Last but not least, the markings about safety certification are also significant. Most electronics products will bear signs of CE, RoHs and FCC. CE and RoHs are required if the product is sold in the EU; while FCC is mandatory for US market. Safety is somehow guaranteed if you see those marks on the power bank.

You will probably find other markings too, such as environmental information. If you are passionate about these environmental factors, you might want to choose a power bank with a ‘cyclic regeneration mark’ which means that it is recyclable.

Know the Conversion Game of Power Banks

You probably know that bigger capacity is better since it can provide more energy. The thing is, there are two different types of capacity: battery capacity and rated capacity. What you usually see on power banks are the battery capacity. What’s the difference between those two numbers? Let’s read on.

1) How many times can the power bank charge your phone?

If a power bank is marked as 10,000mAh 3.8V (38Wh), that means its battery capacity is 10,000mAh, the voltage of the battery core is 3.8V, and the battery core energy is 38Wh.

Rated capacity (mAh): Also known as nameplate capacity, is the least output capacity under the rated voltage and current.

For example, the rated capacity of a power bank is 7,000mAh (TYP5.1V 1A), that means the minimum output capacity of the power bank is 7,000mAh in the charging process with 5.1V and 1A output standard.

Conversion efficiency: This indicates the value difference between the battery core energy and rated capacity.

A power bank has a battery capacity as 10,000mAh; the battery core voltage is 3.8V which will increase to 5.1V when it’s charging a phone. So, in theory, its output capacity is:

10,000 3.8 / 5.1 = 7,450mAh

The rated capacity is 7,000mAh (TYP5.1V 1A), so the rated conversion efficiency is:

7,000 / 7,450 = 93.96%

In other words, the energy conversion efficiency is about 93.96%, with a 5.1V 1A output standard. About 6.04% of the power is lost in the conversion. If you use professional tools to test the rated output capacity, the result would not be too different. The conversion efficiency of most of the power banks on the market are between 80~90%. Therefore, a power bank with 10,000 battery capacity has about 6,000~7,000 rated output capacity.

Charging rate: 7,000mAh (rated capacity of the power bank) / 3,110mAh (capacity of the iPhone 11 battery) =2.25

Therefore, it can charge your iPhone 11 twice at best.

2) How long will the power bank last?

The lifespan of a power bank depends on two things: how well the power bank is made and how much you use it. The number of charge-discharge cycles, decided by the battery core and other vital components, varies amongst power banks. Typically, this is between 300 ~ 1,000 cycles and if you want my advice, you should definitely avoid any power bank that has less than 500 charge cycles.

Say, the power bank has 500 charge cycles, and you fully charge it once per day on average, then how long it will last? We can work that out with the following simple formula:

Power bank lifespan = Charge cycles charging rate / using rate

Where ‘Using rate’ is the number of times you charge the power bank fully in a day.

As mentioned above, for a 10,000mAh power bank, its charging rate is about 2.25. If it has 500 charging cycles, its lifespan is:

500 2.25 / 1 = 1125 days = 3.08 years

But where can these charging cycles be found, you may ask? The test of cycle life involves specific equipment, so for now, we’ll just have to skip that.

But, if you really want to know, ask the seller before you purchase. Even if you don’t get an answer, as you can see from the above example, the power bank will last longer if it has more capacity and a lower use rate. So, it makes sense to go for a big power bank and use it slowly, that way, you should be able to keep for a couple of years if not more.

3) How long does it take to charge the power bank or the phone fully?

Now comes the easy part. The charging time depends on the capacity of the powered device (PD) and its input current which equals the output current of the power sourcing device (PSD)

Charging time = battery capacity / actual input current.

Take a 10,000mAh power bank to demonstrate. Its rated input is 5V/2A, so if you use a 5V/1A power adapter to charge it, its actual input current is 1A=1,000mAh. 10,000mAh /1,000mAh=10 hours. If you use a 5V/2A power adapter, it takes 5 hours to fully charge the power bank: 10,000mAh / 2A (2,000mAh) = 5 hours.

Same for charging the phone. If your phone battery has 4,000mAh capacity, and the maximum output current of the power bank is 2.5A (input current for the phone is 2.5A) then it takes about 1.6 hours to fully charge your phone with the power bank.

How Safe is the Power Bank?

You cannot be too more careful with electronic devices, including power banks. They should have protection mechanisms to prevent any danger caused by electricity.

There are several underlying protection mechanisms: over-current protection, under-voltage protection, short-circuit protection, over-temperature protection and overvoltage protection. This information can usually be found in the user manual.

What’s the Purpose of Power Banks?

By now, you are probably a power bank expert to some extent. But can you count on all those numbers to consider a purchase? Not really. Knowing everything about a power bank can help you decide the quality, but the quality is not the only standard to define a “good” product. It also has to do what you want.

Yes, high-capacity power banks have a longer lifespan and higher charging rate, however, a high capacity also means a bigger size. Do you want to carry a bulky phone power bank in your small bag? Some of you will be shaking your head. If you want to carry an emergency power supply for your phone when you are out shopping, then a small-sized power bank is best. However, if you are a selfie addict, an extra 30% energy from the power bank may not be enough for your day out. You see, everyone has different needs.

Therefore, the first step to select a power bank is to figure out what kind of power bank you want, then compare power banks of the same type with what you’ve learned above.

If you happen to be looking for a power bank for an emergency power supply, check out this recommendation –

PITAKA MagEZ Battery Pack, a MagSafe compatible wireless charging power bank.

With the Slider, you can slide the power bank in the dock when it’s not used, so you won’t misplace or forget to charge the power bank anymore.

In conclusion

You don’t have to be a tech guru to select what you want but, you should know the essential tech behind a power bank if you are going to buy one. Don’t be fooled by the salesman, do your research and you have a bigger chance to get a power bank that’s worth it. Nothing could go amiss.

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).

power, bank, watt

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.

power, bank, watt

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.

The Best USB C Power Banks With PD (Power Delivery)

USB C technology became quite popular in recent years, with more and more devices using it by default. So if you happen to have a phone, tablet, or laptop with USB-C ports, then you might also want to have a 100% compatible power bank as well. Otherwise, you’ll either end up using all sorts of adapters and you’ll be giving up on speed and efficiency.

This is why we made this in-depth research on the USB C power banks available on the market and shortlisted the best of them here. The main criteria we took into consideration were:

  • USB C ports for both output and input
  • The power banks must use the PD (power delivery) technology
  • They should have a fast recharging time

So without further ado, here are the best USB C power banks in our opinion:

Best overall: RAVPower 20000mAh PD 60W

  • Recharging time: 3 hours
  • Weight: 14.4 oz / 408 g

RAVPower has truly outdone itself with this 20000mAh power bank from their PD Pioneer series. They managed to create a device that’s not only powerful and fast but also has a great design. Considering the price point too, we can go on a limb and say that this is one of the best options on the market for someone looking to buy a truly dependable USB type C power bank.

Capacity-wise, it’s not too small but not too large as well. It holds enough charge to replenish an iPhone 11 Pro Max 2.6 times, an iPad Pro 2018 1. 6 times, or a MacBook Pro 13″ 2018 0.84 times. This makes it perfect for daily use. You can even depend on it for several days at a time if you only need it for your smartphone.

Regarding the power output, it comes with a generous 60W maximum output via its USB C port with Power Delivery. This is enough to charge power-hungry devices such as laptops, gaming consoles, drones, etc. Besides the USB type C port, it also features a USB type A port that comes with a fast-charging technology called iSmart.

It’s also worth mentioning that the RAVPower 20000mAh PD power bank has a sturdy build. The casing is made out of thick, scratch-proof plastic with a matte surface which gives it non-slip properties. The only real downside we see to this device is the fact that it could have featured one or two extra ports.

Meanwhile, the DC 12V/5A cigarette lighter port is capable of powering CPAP machines, such as Philips Dreamstation, Resmed Airsense/Aircurve 10, and Resmed S9. However, to take advantage of this, you will need a CPAP adapter.

This power bank is suitable for your needs if you’re going camping, on a road trip, or hiking. Place it inside the storage bag, and you’re good to go! It has a built-in flashlight for your lightning needs when you’re in a dark environment. Even cooler, you can wirelessly charge your smartphone.

You can also fully charge it in 5-6 hours by using the bi-directional USB-C port. Using a wall outlet will take 7-8 hours.

The Omnicharge Omni 20 is one of the highest-quality power banks you can find.

USB C technology explained

For a long time, the general standard in device connectivity was the USB Type-A with its micro and mini versions. Regardless of the USB A ports version (1, 2, 3), the rectangle connectors that never fit on the first time, were ubiquitous. And to some extent, they still are.

However, things are about to change with the new USB Type C technology which shapes itself up to be the new standard in terms of connectivity. and more devices are starting to adopt this new type of port. Even Apple is on the way to replacing its famous Lightning ports with USB-C ports. And this speaks volumes about the new kid on the block, as Apple has been notoriously defensive towards their own patented technologies.

The main benefits of USB C technology are:

  • it can transmit both power and information simultaneously
  • information can be transferred at much higher speed rates of up to 10 Gbps
  • the plugs can be inserted either way, there is no right way up as in the case of USB A ports
  • these ports can be used for both input and output of power and/or information

Things tend to get a bit more complicated when you factor in the fact that USB-C is more of an umbrella term. In fact, these connectors can utilize different types of protocols such as USB 3.1 or PD (power delivery).

Power Delivery (PD)

USB-C output ports with Power Delivery (PD) can supply up to 100 watts of power. This is an important feature, as older generation USB ports could supply just 2.5 watts on average, enough for a phone but definitely not enough for a laptop that requires at least 60 watts. This is why for the list of power banks we only selected ones that have the PD feature.

However, this is not to say that all PD ports supply 100W. There can be different values of power output, but the most common ones are:

  • 18W – this is enough for all types of smartphones and tablets, including devices such as the Nintendo Switch.
  • 30W – 45W – from these levels, you can start charging more power-intensive items such as laptops, just that they will take longer to charge than usual
  • 60W – starting with 60W most laptops will charge without an issue, not to mention tablets, cameras, or phones.

Wrap-up

It’s pretty clear that the USB-C ports are here to stay and that they are very likely to become the next standard in terms of connectivity. As more and more devices will come with this type of port, then it makes sense to make sure any power bank you buy also has USB-C compatibility.

But besides plain old compatibility, one of the biggest advantages of USB C power banks is their increased speed, where PD technology plays a key role. The maximum loading speeds of traditional ports, don’t even come close to the ones provided by USB-C with PD.

This product recommendation list is dynamic. As newer models of power banks with USB-C ports get launched, we’ll update it in order to feature the best models available on the market.
