The best power bank deals available now
Our best power bank overall comes in a long, slim design that makes it easy to carry. The Anker PowerCore 20100 power bank boasts a generous 20,100mAh battery capacity, which is enough to charge multiple devices several times on a single trip. In fact, it will charge an iPhone 8 about six times and a Samsung Galaxy S9 about four times.
It has two 2.4 Amp USB ports so you can charge two devices at once, and it charges fast if your devices use PowerIQ or VoltageBoost (there's a separate version available to buy if you have a device that uses Qualcomm QuickCharge). It all comes in at a very reasonable price. As long as your device is compatible and lightness is not your main concern (it weighs about the same as a can of soup), this portable charger ticks all the boxes.

If you'll need to charge more than two devices at once, the MAXOAK 50,000mAh Power Bank could be the option you're looking for. It boasts an impressive six ports and an astounding 50,000mAh power capacity to feed them.
Unfortunately, it's not compatible with MacBooks, but it can be used to charge laptops from Fujitsu, Sony, Acer, Asus, IBM, Dell, HP, NEC, Samsung and Lenovo. The enormous battery capacity and multiple ports make this an ideal power bank for a trip with colleagues who'll need to charge their devices at the same time, or if you simply have a lot of devices yourself.
The RAVPower 20,000mAh is another slim and stylish power bank that offers a good amount of battery life and multiple charging options despite its svelte design. It's easy to slip into a pocket and has three ports (usb c, usb 3.0 and usb 2.0) that allow multiple devices to be charged at the same time.
This power bank also comes in at a very reasonable price considering its capacity, making it a good choice if you want a dependable power bank that offers multiple charges without breaking the bank.
If you're mainly after a power bank to keep your iPhone and/or iPad in juice, then the Mophie Powerstation Plus XL is a smart choice. It has a built-in dual-purpose charging cable with a Lightning adapter for charging Apple devices. The adapter can be easily removed if you want to switch it to micro USB, for example, to charge an Android phone.
Models range from a 6,000mAh capacity at the most economic end up to a more generous 12,000mAh, which is enough for more than four additional charges on your iPhone or one extra charge for a tablet. A second USB port means you can charge two devices at the same time.
The Anker PowerCore II power bank has a lower battery capacity than most options on our list, but it's also one of the most compact. Smaller than a pack of playing cards, it only has one port but still has enough capacity to charge an iPhone around three times. If you need a power bank that you can comfortably slip into a pocket and use to quickly charge your smartphone a couple of times while you're out on the move, this could strike the right balance between size and capacity.
The AUKEY Power Bank 20,000mAh offers dual USB ports to charge two devices at once and a decent battery capacity to support them. On top of that, it's cleverly optimised to promote healthy battery life. However, perhaps the most interesting part of the package is the 24-month warranty, which is much more generous than other devices on our list. It might not be relevant if you like to upgrade your devices regularly, but if you want to get at least a couple of years' use out of your power bank, it might be a deciding factor.
If money is no object, then the Omni 20 USB-C Portable Power Bank is perhaps the best power bank out there. It's not the most compact, but this high-powered device offers four ports (two USB and two USC) and serves as both a laptop charger and a USB hub, allowing you to potentially charge two laptops and two smart devices at the same time.
It charges fast – in under three hours when plugged in by itself. You can also charge the power bank itself while your devices are charging. It’s a lot more expensive than most of the other power banks on our list, but if you need to use your devices a lot, the investment could pay off by allowing you to work for longer.
The iMuto Ultra High Capacity portable charger is another compact power bank that offers high battery capacity at an affordable price. Storing 20,000mAh, it can charge an average smartphone over four times on a single full charge. It's not the smallest power bank in terms of size, but at such an attractive price it's a good option for creatives that need to have a decent amount of power to fall back on.
The RAVPower 6700mAh charger is incredibly cheap but still offers enough power to charge an empty smartphone at least once, and probably twice. It weighs about the same as the average phone, and it's compact enough to easily carry in most pockets. It's compatible with a wide range of devices, making it a great budget choice for a convenient power bank with moderate power for casual use on a night out or weekend away.
RAVPower covers the entire spectrum, from some of the best affordable compact power banks to high-end options. This RAVPower Power Bank with AC Outlet is the ideal choice if you have more cash to splash and want to be able to charge multiple devices, such as a MacBook or Surface Pro as well as your smartphone. With both a Type-C (5V/3A) port and iSmart USB (5V/2.4A) port, you’ll be able to charge both at the same time, as there’s plenty of battery capacity (20,000mAh).
If you only need to charge one device you can do so over and over again: an iPhone 7 around five times, a Galaxy S7 four times, or the 12-in MacBook once, for example.
How to choose the best power bank
When choosing the best power bank for your needs, the first consideration should be battery capacity. Consider how long you’ll be on the move and how many devices you'll be using. You'll also need to bear in mind how much energy those devices consume as a laptop or camera will need more power to recharge than a phone or tablet.
Once you've decided what battery capacity you need, the next factor is weight. Usually weight increases in line with capacity, so you might want to strike a balance and sacrifice some battery capacity for the extra portability that comes with a lighter power bank.
Of course, you need to make sure that the power bank you choose is compatible with the devices that you want to charge. If you're likely to need to charge several devices at the same time, you'll want to check how many charging points the power bank has. Many power banks come with two or three, but some power banks offer up to six.
