How we test power banks
We connect power banks through a USB power meter to a range of devices, including Android and iOS smartphones and an Acer Chromebook, to check how much power they output from each of their USB-A and USB-C ports.
We also check their wireless charging capabilities and measure the rate at which they charge from a 65W USB-C charger. Finally, we run a quick charge test to find out how much they can recharge our test smartphone in a 15-minute period.
Our team of experts have been testing and reviewing tech for more than two decades, putting dozens upon dozens of power banks through their paces to determine which are worth recommending to you.
Independence is at the heart of everything we do and these recommendations cannot be bought. Each product on this page has earned its spot in the fires of our rigorous testing methodology, so you can be sure that our picks are reliable and based on factual data.
The best power banks you can buy in 2026
1. Anker Prime A110A: Best power bank overall
Price when reviewed: £180 | Check price at Amazon
Reviewed by Stuart Andrews
- Great for… outstanding charging speeds and useful digital display
- Not so great for… those on a budget
The Anker Prime A110A is the definition of excess. It has a staggering capacity of 26,250mAh – enough to fully charge your laptop and juice your smartphone several times over – and supports super-fast 300W charging allowing for the simultaneous speedy charging of multiple devices. In short, if you need a lot of power, this is the way to get it.
Its two USB-C ports can both output a maximum of 140W at the same time, and you can even tuck a lower-power device into the USB-A port at up to 20W and charge three things at once. You can check the various output levels via the incredibly useful touchscreen, which also can monitor charging status, current temperature and you can do this via Anker’s companion app, which connects to the power bank via Bluetooth.
All of this quality does come at a price, however, with £180 being quite expensive for a power bank.

- Great for… portability
- Not so great for… wireless charging
The Cuktech 10 Mini is cheap but it packs more of a punch than you might think for the money. You get three ports here: two USB-Cs that can charge at up to 55W and a USB-A port that supports charging up to 33W, it has a total capacity of 10,000mAh – enough for roughly two full smartphone charges – and there’s enough output power to juice up a laptop and a phone at the same time.
The build is slight enough to comfortably slip into a bag or a pocket and, at 216g, it weighs roughly the same as a flagship smartphone. There’s a useful little LED display, too, which lights up at the press of a button to show you current charging status and battery level.
As for negatives, there are impressively few. There’s no wireless charging and the claimed 55W peak speed only applies to laptops and some Xiaomi phones – our test Android handset hit around 40W. Otherwise, this is a value-packed charger with great speeds and a keen price.

- Great for… fast charging multiple devices
- Not so great for… portability
Our reviewer Stuart Andrews describes the UGreen Nexode PB771 as a “mini-tower of power”, and it’s hard to argue: with its massive 20,000mAh capacity, maximum combined output of 145W and fold-out MagSafe wireless charging pad, the PB771 is a feature-rich charger that’s ideal for keeping your phone, laptop and/or handheld gaming console juiced-up on a long weekend away.
In our testing, we found the UGreen to be more than capable of charging two power-hungry devices at the same time, delivering 98W from the rear USB-C and 42W from the front simultaneously. You’ve also got a USB-A port that can deliver up to 22.5W and that Qi2 MagSafe pad reaches up to 15W.
It’s a little bulkier and heavier than some rivals, so isn’t as easy to slip in a bag or a pocket, but for charging multiple devices quickly, the UGreen Nexode PB771 is an excellent choice at a very appealing price.

4. Iniu SnapGo Air: Best MagSafe wireless power bank

- Great for… speedy Qi2.2 wireless charging
- Not so great for… wireless charging inconsistent on some phones
With support for Qi2.2 wireless charging, the Iniu SnapGo Air is better than most rivals at charging compatible devices as fast as possible. Using a QI2 iPhone 13 mini in testing, we found that the SnapGo Air charged the battery 25% in 15 minutes – the fastest we’ve ever recorded. Wired charging is excellent, too, charging our test laptop at a steady 43.5W.
The other key benefit here is the sleek build, which means you can easily snap it onto the back of your phone (provided either it or your case has magnets) and still fit it in your pocket. Equally, the 196g weight is on the lighter side and the anodised aluminium casing feels robust enough to survive rattling around in a backpack.
The only issue in testing was that certain phones failed to achieve their stated peak wireless charging speeds. If you have a Qi2.2 phone, however, and want a sleek and powerful wireless charger for it, the Iniu SnapGo Air should be in your basket.

- Great for… huge capacity and fast charging speeds
- Not so great for… wireless charging
As the name suggests, the Anker Laptop Power Bank packs enough of a punch to keep your PC juiced up when on the go, and we found that its combination of powerful charging and high battery capacity makes it the perfect companion for long-haul flights.
Whether you’re getting work done, watching movies on your phone, gaming on a handheld, or all of the above, the Anker Laptop Power Bank has the capacity to keep your devices juiced up. At the same time, even – the power bank can output 165W with two USB-C devices connected or 133W with one USB-C and one USB-A.
In our testing, the Anker Laptop Power Bank brought our sample MacBook from empty to 30% in just 21 minutes – we were even able to plug in a second laptop without affecting the charging speeds of the first. Impressive stuff.
It would have been nice to see wireless charging included, and it’s quite chunky, so one for your carry-on rather than your pocket, but anyone staring down a long flight will find the Anker Laptop Power Bank to be the ideal travel companion.

How to choose the best power bank or charger for you
What kind of power bank should I buy?
Basically, you’re trying to balance four factors: size, speed, capacity and price. The rules are simple enough: the less you spend, the lower the capacity and the slower the power bank will charge.
Cheap power banks
The cheapest and smallest power banks will have a capacity of between 2,500mAh and 10,000mAh. These days we’d avoid anything below 5,000mAh, as it won’t have enough charge to refuel most recent smartphones. At the upper end of this range, though, you’ll have sufficient capacity to recharge your phone or give a tablet a decent boost – and you can find one the size of a smartphone or a Mars Bar for around £12 to £18.
Mid-range power banks
Spend £18 to £30 and you’re looking at power banks with a 10,000-20,000mAh capacity and better connectivity, with USB-C connections now pretty much standard. You may get an increase in size and weight to match; 20,000mAh batteries can be roughly the size of a big-screen smartphone, but they’re also a good 50% heavier. However, you’ll also have much faster charging, with Quick Charge 4 and USB PD.
Expensive power banks
Splash out more than £30 and you can bag an even bigger power bank, with capacities starting out at 20,000mAh and going all the way up to 26,800mAh or more. USB-C with Quick Charge 4 and USB-PD will be a given, making up for the fact that you’re carrying a heavier brick of a charger. The advantage is that you’ll be able to top up multiple devices, often simultaneously, and you’ll have enough charge to keep them going for a whole weekend or even longer.
What else should I look out for?
Most power banks now use a USB-C port to recharge, although some models will have a micro-USB port as well to ensure compatibility with older chargers. Don’t worry if you don’t have the required cable, as one will usually be provided in the box.
One advantage of this shift to USB-C is that power banks now support USB PD for faster charging. This means your power bank will often recharge faster when connected to a suitable fast charger, at anywhere from 20W to 60W. At those speeds, even a high-capacity charger can recharge fully in three to four hours.
As for charging your devices, you’ll usually have a choice of USB-A and USB-C ports, with the latter supporting the fastest USB PD charging standards. All power banks and smartphones support the USB BC 1.2 standard, which can deliver up to 7.5W over USB-A or 15W over USB-C. Most also support the USB Power Delivery (PD) 3 standard, which increases the maximum voltage and current to deliver up to 100W of power – enough to charge a lightweight laptop at a decent speed. Not all USB PD power banks can push out that much juice; you’ll often find them limited to 15W, 27W, 45W or the maximum 100W, but even 27W will cover you for fast charging on a wide range of smartphones and tablets.
We’re now also seeing the first power banks supporting the USB PD 3.1 spec, meaning they can deliver over 100W with compatible devices and cables. Right now, these don’t go over 28V at 5A for a maximum of 140W, but we may see power banks with 180W or 240W outputs in the future. That’s overkill for smartphones, but a potential game-changer for power-hungry laptops and tablets.
Beyond that, there are Qualcomm’s Quick Charge standards. The most common is Quick Charge 4, which pushes out a maximum 21V and 4.6A for 100W of output. It’s also compatible with USB PD, which is lucky, as Quick Charge 4 hasn’t had as much love from power bank manufacturers as the old Quick Charge 3 standard, with most standardising around USB PD. The same applies to the new Quick Charge 5, even though the latter can charge compatible phones to 50% within five minutes when using the right charger. It’s not hard to see why: USB PD is supported by Apple and Google’s recent devices and still delivers fast charging on Quick Charge 4 and Quick Charge 5 phones. More importantly, it’s an open standard without any licensing costs.
Is it worth paying extra for a fast-charging power bank?
Yes. There’s very little difference in terms of price these days, and even if your existing phone doesn’t support Quick Charge 4 or USB PD, there’s a good chance that your next one will. In fact, there’s an argument that the smartest thing to do is standardise around USB PD and ensure that your power banks, chargers, smartphones and tablets can all run under the same charging ecosystem, giving you fast charging whenever you need it.
What about charging wireless earbuds, Bluetooth headphones and other accessories?
Smaller accessories such as wireless earbuds, Bluetooth headphones, fitness trackers and smartwatches can cause problems for power banks because they’re designed to charge using a low-wattage trickle-charge, rather than the 10W to 25W used to fast-charge your typical smartphone. Either there’s a risk of damaging the accessory or its charging case, or the smarter power banks can even shut down due to the low demand. However, some power banks now include a trickle charge mode designed specifically to charge these devices safely. If you’re planning a long weekend (or longer) away where you’ll need a recharge, this is one feature worth looking out for.
What about wireless charging?
If you care more about convenience than speed, wireless charging is very much the way to go – and a growing number of power banks support it. Just place your smartphone on the integrated wireless pad, and you can recharge without connecting any cables. There will be a hit on charging speeds, so you’ll be limited to 7.5W or 10W, but that’s not a big issue if you don’t need to recharge in a flash. As a bonus, we’re now seeing Magsafe-friendly chargers that will clamp onto an iPhone or a ring inside an iPhone case, meaning you can recharge your iPhone even while you’re using it.
