lcd display power bank brands

Traveling nowadays typically involves taking along multiple devices—smartphone, tablet, laptop, and the like. But you won’t always have access to a wall outlet to charge all, or even any, of them. That’s why it’s important to add a power bank to your pack. With so many options available, how do you know which power bank best suits your needs? Everything from various charging specs, to different ports, to the included cables need to be considered before making a purchase. It’s enough to leave a buyer scratching their head.

That’s where we come in. We’ve tested a ton of power banks from different manufacturers spanning the range of available price points and specs. We’ve curated a list of our favorites to help you find the best value. You can rest assured that our recommendations are all great picks as the PCWorld staff puts each power bank through a battery—pun intended—of tests. You can learn more about our evaluation process below our picks.

While our recommendations reflect a range of needs, if you spend a lot of time commuting you might also consider our roundup of USB car chargers. Additionally, check out our roundup of best power stations if you’re looking for something more substantial that can power your appliances while off-grid or in an emergency.

Building on the success of the Powerstation Plus XL (our previous pick for best overall power bank), Mophie’s Powerstation XXL matches its predecessor in efficiency, achieving 92.51 percent of its stated maximum current, plus it’s stylish, portable, and affordably priced. It’s a no-brainer recommendation if you’re in the market for a dependable power source on-the-go.

With above-average efficiency, a rugged case, and Power Delivery, Otterbox’s Fast Charge power bank is a great option for your bag. It could easily be our pick for best overall power bank, if not for the fact that our top pick—Mophie’s Powerstation XXL features more ports.

With its stylish fabric-clad body, its discreet yet useful battery-status display, and its three USB ports (one of which is USB-C), Einova’s power bank adds flair and above-average battery efficiency to your everyday carry.

The combination wall charger and portable power bank format makes the Powercore Fusion 5000 exceedingly convenient. The bank itself can be recharged via either method—power outlet or MicroUSB port. It’s limited to two USB-A ports for device charging, but that doesn’t dimish its great handiness-to-cost ratio.

If you spend a lot of time on the road and value device preparedness, the Sherpa 100AC makes a trusty, if pricey, companion. Yes, at $299.95, you’re looking at a big investment. But that buys you two USB-C ports capable of fast-charging speeds, two standard USB ports, a Qi wireless charging pad, a standard U.S. 110V outlet, a full complement of cables, and a nifty status display and buttons for controlling various functions of the pack. The pack itself can be charged in just a couple hours.

Belkin’s Charge Plus 10K USB-C Power Bank is a capable mobile companion in its own right—both its USB-C and Thunderbolt ports are capable of delivering 18W of battery power to your device, or 23W total if both ports are used simultaneously. But it’s the built-in cables for each port that really sets this power bank apart. Of course, you’ll pay a slight premium for the convenience.

There are times when a mere power bank isn’t enough—the circumstances call for a power station.Say you’re spending the weekend off the grid. Or you want to be prepared for a future emergency. The RAVPower Portable Power Station 252.7Wh Power House will get the job done. With a capacity near 252.7Wh, a nice complement of ports, a built-in flashlight, and an included carrying case, this highly portable power station makes a great travel companion for road trips. (For more options, see our roundup of best portable power stations.)

Determining whether a power bank lives up to a company’s promise entails more than simply connecting it to a phone and charging. Testing battery packs is done over weeks, not days, and requires extra equipment in order to ensure the batteries work as expected.

As we use the DROK load tester to drain the pack of power, we are able to test against a battery’s stated maximum current, and verify that proper shutdown mechanisms are in place should something go wrong during a charging session (such as a device drawing over the maximum amps).

By using the AVHzY USB Power Meter, we are able to monitor volts and amps, total power throughput, and total amount of time to deplete a battery from full to empty. The meter can create an Excel spreadsheet of the entire process for future reference.

Power banks are most commonly intended to charge mobile devices such as cellphones, tablets, cameras, and portable speakers. They can also be used to charge laptops provided the ports allow for it and the power charging rate is compatible.

Power banks are generally not suited to charging larger electronic devices in your home. If you’re looking for a backup power source during an emergency or while camping, you should instead opt for a power station.

The mAh (milliampere per hour) capacity rating refers to the available storage capacity for a battery. A higher number means that the battery can store more energy and has a longer battery life when charging a device. So for example, an iPhone 13 Pro Max’s battery is rated at 4,352 mAh. This means that a power bank with 10,000 mAh can fully recharge that phone a little over twice before running out of power.

For a portable power bank that you can easily travel with, you should look for a minimum of 10,000 mAh. Most models nowadays even offer 20,000 mAh for reasonable prices. The more mAh, the better, just be sure to weigh your capacity needs against the physical size of the power bank.

Generally, the more mAh a power bank has, the larger its physical size and the heavier it is as well. Therefore, it is recommended when looking at a power bank, that you first consider the amount of power you need to charge your devices and then adjust your expectations based on the size and weight you are willing to carry around with you.

How fast your power bank can charge a device is dependent upon the available output of the power bank and the available input of the device. Without getting too much into the electrical details, a standard 3,000mAh device such as a smartphone can be expected to charge in about 90 minutes by most power banks. However, many power banks nowadays come with quick charge technology, which helps speed up the process even more. Larger devices such as tablets and laptops may take much longer to charge as they require much higher inputs than smartphones.

Always double-check that the power bank you want has an output that matches or exceeds the input of your device to ensure the fastest possible charging.

Power bank lifespan is determined by a few factors such as how often you charge the power bank, the quality of the power bank itself, and the conditions in which the power bank is kept. That being said, you should expect a high-quality power bank that is charged every few days and kept in a cool dry place to last several years or more.

The best power banks are ideal for keeping your devices charged even without an outlet nearby. Gadgets keep getting more powerful but battery life remains a limitation. That means a power bank is essential for smartphones, laptops, and other battery-powered devices.

Before choosing one, you need to think about what type of power bank is best for your needs. Consider capacity, portability, and price. If you need to power several phones, tablets, and other mobile devices, you"ll need something with high capacity, but not everyone will.

If you"re looking to charge a laptop, Steam Deck or Nintendo Switch, those requirements go even higher. If you prefer to travel light, something slim and lightweight may be better. You might need to sacrifice capacity or spend more, but it could be worth it, depending on when you’re most likely going to have to depend on your power bank..

We"ve listed all the best power banks for all users, considering different needs and budgets. There"s something for everyone here, but if you need a laptop charger, check out our best portable laptop charger guide instead.

The best everyday power banks are fairly straight forward. These tend to be the ones you take for your usual day to work and back again. We"re talking middling capacities while being easy enough to carry but not quite as lightweight or as slim as those categories. They"re solid all-rounders even though they might not excel at any one thing. They do have the advantage of being typically well priced for what they offer, however.

Offering mostly everything you could need at this price, the iMuto 20,000mah power bank has a 20,000mAh capacity that means you can charge the average smartphone over four times without a problem. The price is that it"s a fairly bulky power bank and it"s certainly heavy but with two ports and a screen that shows you how much charge is remaining, it"s certainly practical if not particularly portable.

The Anker PowerCore 20,100mAh power bank is a bit more stylish for the price, and still offers a huge 20,100mAh battery so you can recharge multiple times without issue. It doesn"t support Qualcomm"s QuickCharge technology but we"ve found it still recharges pretty quickly with devices that support PowerIQ or VoltageBoost.

The Mophie Powerstation Plus XL 10,000mAh power bank is ideally designed for iPhones and iPads thanks to its embedded Lightning cable. Besides that, the power bank has a smart soft fabric finish that looks rather nice compared to the typically plastic exterior of most power banks. It can charge two devices at once too via the 10W USB-A port and the integrated charger.

The Veho Pebble P1 Pro 10,400mAh power bank doesn"t look like other power banks because it uses a curved edge design. That might not work for everyone but it makes it quite sleek and stylish in our eyes. Able to recharge most phones at least two and a half times, it can charge via microUSB or USB-C which is pretty convenient much of the time, plus it"s fast too.

The Omars Mini Power Bank 10,000mAh Battery allows you to charge up to three devices at once thanks to its one USB-C and two USB-A ports. It doesn"t offer full USB-C speeds due to how it charges but it"s not a great loss if you need to charge up multiple devices at once. Its small form is certainly useful when tossing it into a bag.

The best lightweight power banks rarely offer the most capacity but they"re easy to store. The kind of devices you hardly notice you"re carrying, they"re there to help you out of a jam. While you won"t be using them to recharge your laptop or games console, they"re good for a quick boost to your phone when you"ve realized you overestimated your battery"s capabilities.

The Mophie Powerstation Mini Universal Battery looks pretty nice for the price and is lightweight. Capacity is a mere 5,000mAh, but that"s fine for daily use. You can charge multiple devices at once via the USB-C and USB-A ports. An integrated four-light LED power indicator shows you the charging status and current battery life. It feels good in your hands too.

The EAFU Power Bank does more than just charge your phone and devices. It also has a built-in flashlight which is useful for when you"re camping or suffering from a power cut. Capable of charging up to three devices at once, you might run out of juice faster than you"d like but that"s reasonable for a device that"s small and lightweight enough to fit into your pocket.

Small enough to fit into your hand, the JvGoal Power Banks 12000mAh will still charge your iPhone a few times and let you know exactly what"s going on via its LCD display. The display shows the remaining power so you"re in control with two USB output ports to give you some flexibility. It"s impressive what it packs into such a small design.

The Anker PowerCore 13000 Power Bank looks bulky but it"s surprisingly lightweight. Packing in plenty of juice for the price and size, it can charge an iPhone a couple of times without a problem as well as a tablet from 0% to 100%. There"s no Qualcomm Quick Charge support but it"s still pretty speedy. A matte finish makes it easy to grip too.

The best high capacity power banks are designed for power. That means they"re typically fairly bulky and sometimes unwieldy things that you"re definitely going to notice in your bag but they"re built to last which is a huge help. If you need to be able to recharge all your devices multiple times and over a number of days, these are the power banks you need. Look out for how many ports they offer for maximum effectiveness.

Need to recharge everything you own and all at the same time? The MAXOAK 50,000mAh power bank is the one for you. It can charge six devices at once with its 50,000mAh capacity meaning you won"t run out of power any time soon. It"s capable of dealing with laptops and the Nintendo switch as easily as it is your smartphone or tablet so it"s great if you"re off the grid for a while

Charmast is a less well known brand compared to other power bank supplies but it"s keenly priced. It can charge your iPhone over 8 times as well as a MacBook twice with a choice of USB-C or regular USB-A. Its capacity isn"t as vast as some options here but it"s surprisingly slim and lightweight for what it offers meaning it"s pretty convenient.

Jiga reckons the Jiga 30,000mAh Power Bank will also most people about a week and that sounds about right. Able to charge an iPhone 12 over ten times, it"s certainly powerful. Alongside that is a a useful flashlight feature for camping and a 5-segment LED indicator so you know how much power you have remaining at all times. Just look out for its bulkiness.

The Bextoo Power Bank 30,000mAh only has two USB ports which is a bit of a shame but it"s surprisingly stylish for a power bank which should appeal to some users. An LCD display shows remaining power at all times and you should be good to go for nearly 10 phone recharges. Micro-USB and USB-C are both supported which is convenient.

The best slim power banks are slim enough that you don"t have to plan ahead when taking them anywhere. They"ll fit into your lifestyle well even though they might not offer the best capacity or the most features. We"re talking convenience over function but that"s great if you want to keep things light. Look out for enough power to keep your phone recharged a few times but don"t count on recharging your laptop so easily with these and there probably won"t be too many port options either.

The Belkin 5,000mAh power bank is pretty small in capacity but that also means it"s very slim too. You"ll still be able to charge your phone a couple of times and it"s MFI certified so you know it"ll work well with all your Apple devices, as well as anything else you throw at it. If portability is everything, this is a reliable option from a good name.

INIU is a less well known brand than some listed here but its INIU Power Bank offers a lot of features for the price. Still reasonably slimline, it has a built-in flashlight, the ability to charge up to three devices at once, plus bundles in a USB-C cable. Its 10,000mAh capacity is rather good for the size too so you"ll be able to recharge plenty of devices.

Slim if a little long, the Anker Power Bank PowerCore Slim 10,000mAh is a reputable power bank from a reputable name. It can charge your iPhone 12 at least two times with a full charge for an iPad too thanks to its 10,000mAh capacity. It"s about the size of many smartphones which isn"t as sleek as some but Anker is a reliable name so you know you"re guaranteed of safety here.

The Anker Power Bank 20,000 is a bit of a beast for its size. It has a massive 20,000mAh capacity but is still slim enough to feature here. You can charge two devices at once with both USB-C and Micro USB an option with more than five charges for the iPhone XS easily possible. Just look out for the fact it"s not quite the speediest of chargers although PowerIQ and VoltageBoost helps out here.

The TNTOR 5,000mAh Power Bank might not have the greatest of capacities but look how tiny it is! Smaller than a smartphone, you can slip it in your pocket without thinking about it. Despite that small stature, it still packs in USB-C, USB-A and micro-USB ports and can charge your phone over once throughout the day. Not bad for something you may fear misplacing.

The best wireless power banks mean you don"t need to worry about carrying too many cables with you to recharge your devices. Utilizing many Apple and Android devices" abilities to charge wirelessly, you get all the convenience of a wire-free existence while on the move. Like with the everyday power banks, capacity can vary massively here depending on your budget but don"t count on it being too high given the technology used. Convenience is the priority here.

Need to charge your iPhone 12 and don"t want to stop moving? The Anker Magnetic Wireless 5,000mAh power bank uses magnets to attach to the back of your phone so you can keep doing whatever you"re doing. Of course, it"s a bit limited for non-iPhone 12 users although there is a USB-C port included, but that"s hardly the point. For a specific scenario, you can"t fault the convenience here.

The iWALK Magnetic Wireless Power Bank uses a mixture of a finger ring for you to grip on to s well as Mag-Suction technology to keep your phone and your wireless power bank attached together. It"s a little awkward but the iWALK Magnetic Wireless Power Bank is well priced which makes up for it. Its 6,000mAh capacity should mean you won"t ahem to worry about finding power too soon either, plus there"s a LED that lets you know what"s going on.

Capable of being used as a charging pad as well as a wireless power bank, the Anker PowerCore III Wireless Power Bank is rather flexible. It has USB-A and USB-C ports as well as wireless capabilities with 10,000mAh keeping you at work or play for as long as you need. There"s no device the Anker PowerCore III Wireless Power Bank can"t cope with which is sure to be useful.

Casely"s magnetic wireless power banks only come with 5,000mAh capacity, which means that your iPhone 12 or newer will only get one full charge from it at most. But, its portability and MagSafe capability are what have us relying on it for our daily mid-afternoon juice up. It also comes in multiple colorways so you can get the design that matches your current color palette.

If you"re looking for the best solar power banks, you"re probably planning on being outdoors quite a lot. While you haven"t gone off the grid entirely, it"s useful to know you can recharge your phone or other devices without being near civilization. Solar power banks tend to have the same features as regular power banks but it"s important to check these match with your needs and budget.

There"s no need to slum it with a solar power bank as the Hiluckey Wireless Solar Charger demonstrates. It offers wireless charging functionality as well as the ability to charge four devices simultaneously. With a hefty capability of 26,800mAh, that should be good for most camping trips with a flashlight also helping you out. It even has an SOS mode although hopefully you"ll never need it.

The DJRoll 36,000mAh Power Bank is heavy but it offers a lot. That includes a whopping 36,000mAh capacity which will help you charge your phone multiple times without a problem as well as tablets. It has Qi wireless charging along with built-in dual USB outputs and one USB-C port too so in all, you can charge up to four devices at once. A built-in flashlight with emergency modes and simple hooks for attaching the solar panel complete the package.

Appreciating you"re outdoors, the Anker PowerCore Solar 20,000mAh is designed to handle dust, rain, and a few knocks thanks to its IP65 rating. Alongside that, it"s pretty potent with 20,000mAh capacity but bear in mind there"s only two ports which is a bit of a shame. Still, it"s very easy to use and doubles up as a flashlight with its handle making that extra simple.Looking for a laptop charger? Here are our best portable laptop chargers. We"ve also featured the best portable projectors(opens in new tab).

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 pocket or bag.

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.

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.

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.

There was a time when power banks with LCD displays were rather expensive, but prices 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 pocket!

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.

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.

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.

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.

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.

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.

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.

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.

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.
