We use our smartphones a lot and sometimes find ourselves a little lower on battery than we’d like. That’s why getting a decent power bank to let you top up while you’re away from a plug socket is a sensible investment.
Buying just one power bank covers potential battery emergencies for phones, tablets, smartwatches and even the Nintendo Switch. Some mammoth power banks can even charge laptops. If your gadget is powered up over a USB cable then a power bank will save the day.
Power banks are one of those tech accessories that you know you need, but there are too many of them to choose from. It’s hard to pick which one is best for you and your gadgets. It’s also not that exciting a tech purchase, making the range of choices overwhelming.
We’ve picked out fifteen of the best power banks based on battery capacity, safety and design.

Best power banks for capacity
iMuto 20,000mAh power bank
Two ports, 20,000mAh and affordable
Has a screen
If you're looking for a high capacity charger that's portable, the iMuto 20,000mAh portable charger may be for you. It offers a 20,000mAh capacity that will be able to charge your average smartphone over four times and still have some charge left.
What makes the iMuto a little more useful than the other charging banks on this list is the fact you can see its exact remaining charge, not a rough estimate like in some of the competitors, so you know how much more you can charge your devices for. Sure, the body of the power bank is a little large and ungainly, but the screen more than makes up for it
RAVPower 20,000mAh power bank
Two ports, and slimmer than the iMuto
The RAVPower 20,000mAh doesn't look much different to a lot of the options above and below, but it offers a lot of capacity and can be cheaper than the other devices surrounding it.
You have two ports here so you can charge two gadgets at the same time and it'll have enough capacity to be able to charge both a mobile and an iPad or tablet from 0% too. It's lighter and more streamlined than other banks on this list, so unlike the competition it can actually fit in pockets (well, unless you've got a small pocket).
Anker PowerCore 20,100 power bank
A whole 20,100mAh to play with
Big battery size
High speed charging
Doesn't support Qualcomm Quick Charge
You've likely heard of Anker, and this is one of the company's best portable chargers. It comes with a huge 20,100mAh battery inside, meaning this will be able to charge up your phone or tablet multiple times before it needs a recharge.
We found it pretty snappy to use, in that it charges up quickly, and can also power up your devices speedily. Sure, it did heat up a bit when we were charging it, more so than other devices, but not to worrying degrees. This high-speed charging isn't available for all devices, only for if they use PowerIQ or VoltageBoost. It won't be able to use Qualcomm's QuickCharge technology, but it'll still boost your device when you're on the go.
Aukey power bank 20,000mAh
Charge two at a time
Large battery capacity
Two USB ports
No quick charging
This power bank features two ports so you can charge both your phone and your tablet at the same time and also has a light to show you how much battery charge is leftover. That's quite a standard feature on a larger power bank, but still useful for many people.
The blocky design may not be for everyone, and it's the prime reason this piece of tech isn't higher in this list, but this portable charger should be able to charge your phone and other gadgets a few times over with such a high capacity cell inside.
RAVPower Universal Power Bank Travel Charger
One for your laptop
RAVPower's portable charger is a great choice if you need a device that can charge both your laptop and your phone. It features USB-C and normal USB outputs as well as an AC output, so you can plug your laptop charger directly in.
There's also a 20,100mAh capacity battery inside, so this will be able to juice up your phone or tablet multiple times before you need to put it back on charge.
NOVOO Power Bank 22500mAh
For when USB-C or Lightning isn't enough
Has a mains port
Variety of connections
Sometimes you don't want to charge a USB-C, microUSB or Lightning device up, and that's why you'll want something like this power bank. It has a socket like you'd find it a wall, letting you plug anything in there.
Sure, it's quite a big device, and most devices you'd plug into the wall might want a little more juice than 22,500mAh. But with a connection of plugs and ports, this is a very malleable piece of tech.
Mophie Powerstation Plus XL
The best portable charger designed for iPhones
Integrated Lightning cable
Great fabric design
Ideal mostly for the iPhone and iPad
Not the cheapest
The Mophie Powerstation Plus XL is one of the best power banks designed for the iPhone and iPad (aside from the new iPad Pro 2018 range with its USB-C port), and we say that for several reasons.
It contains an embedded Lightning cable you can’t lose, it charges via a Lightning cable and you can charge it wirelessly with any Qi charger, so you may already have everything you need.
This 10,000mAh power bank has a soft fabric finish and can charge two devices at once, one via the 10W USB-A port and another with the integrated Lightning charger. You won't find as much use from this portable charger if you're on Android, though it's still possible to use that USB-A port so you can help a friend charge.
Best slim power banks
Xiaomi 10,000mAh Power Bank Pro
A slim, well-crafted portable charger
Portable, metal-clad design
Works for micro USB and USB-C devices
A bit thick
Xiaomi has a hand in some unexpected and disparate sectors of technology, including phones, scooters, kettles, audio and portable chargers. But don't sleep on either, as it's onto something worth checking out.
During our testing, its 10,000mAh Power Bank provided good results, both in terms of its portability and charging potential. While not the fastest charger out there, it was able to charge our Google Pixel 2 in a little over two hours. Thankfully, it's discreet enough that you can bring it with you just about everywhere to plug in when necessary.
It's not rare for a power bank to come with a charging cable, but we appreciate that this one has been built with care to suit both micro USB and USB-C users with the same cable, as seen in the above gallery.
Veho Pebble P1 Pro
Fast charging with a great design
Two USB ports
Charge via microUSB and USB-C
Not a design for everyone
With 10,400mAh inside, two USB outputs and fast charging technology the Pebble P1 Pro may be one of the best all-round power banks you can buy right now. This doesn't have anything to do with the defunct watch brand, but instead it's called the Pebble for its curved edges design.
This should be able to recharge most phones at least two and a half times from a single charge, plus this power bank can be charged up by either microUSB or USB-C so you won't need to have a specific cable with you to pump it up again when it's out of juice.
Poweradd Pilot 2GS 10,000mAh
Metal and sleek
Still quite heavy
Poweradd also offers a great slim portable charger, and it's one of the cheapest options on this list yet boasts a substantial 10,000mAh cell inside.
It may be quite heavy, but this is only 1.3cm thick, making it a great device to slip into your back pocket when you're out and about. You'll want to grab a cable to go with it though as unlike the Iceworks choice above it doesn't come with one built in.
