Having tried out the Anker PowerCore 20100 power bank extensively over a period of a few months, we reckon it's the best power bank you can buy right now. In terms of charge speed, connectivity and price, it's absolutely top-notch – with a hefty battery capacity of 20,100mAh, you'll get a good few charges out of it before needing to top it up.
Slimline and sleek, the Anker PowerCore 20100 power bank can charge two devices simultaneously via its pair of 2.4 Amp USB ports, and if those devices use PowerIQ or VoltageBoost, it'll charge them all the faster.
The best compliment we can pay this power bank is that after trying it out for a little while, our writer immediately went out and bought one of their own. For juicing up smartphones and tablets, it's a top-tier choice. Think you might need something more heavy-duty? In that case, you may want to stroll along to our second choice of charger...
Sometimes, we all just need a little more oomph. The Anker PowerCore III Elite 25600 is so named for its 25,600mAh of battery capacity, meaning that it'll be able to power up even the fattest, most resource-hungry phones without a problem. That's even enough power to fully gas up a MacBook, if you're so inclined, making this an ideal power bank for those who prefer to work on the go.
Able to charge up to three devices at once, the Anker PowerCore III Elite 25600 has a 60W USB-C port and a pair of USB-A ports capable of delivering a total output of 18W between them. There's also a trickle-charging function that's useful for low-power devices.
This is a pretty hefty power bank, weighing in at more than half a kilo. Its price tag is quite hefty too, but if you need the kind of power it's offering, we reckon it does represent good value.
If you want something a bit more lightweight than our first two options, the INIU 10000mAh Portable Charger is a good option. With half the capacity of the Anker PowerCore, it won't give your phone a huge number of charges, but it's a handy slim device to keep handy when out and about.
It's got both USB-A and USB-C outputs, and is capable of charging up to three devices simultaneously. For low-power devices like Bluetooth headphones, Fitbits, smartwatches and the like, it's perfect, and it does it all at an impressively reasonable price tag.
Ideal for a quick end-of-the-day power boost, the INIU 10000mAh Portable Charger is great if you're using an older phone that's starting to hold its charge a little less.
Choosing the best power bank often means having to decide between battery capacity and portability. For our money the best compromise between the two is the Anker PowerCore II. It's ever so slightly smaller than a pack of cards, which means it should fit into any pocket (including women's criminally undersized pockets), but with 10,000mAh on offer it should charge most phones two or three times.
You wouldn't want to depend on it over a few days, but if you need something to quickly charge your smartphone a couple of times while you're out on the move, this offers a great balance between size and capacity.
Here's a contender for the best portable charger for iPhones specifically. The Mophie Powerstation Plus is the perfect choice for anyone with an iPhone or older iPad that needs the occasional boost, as it has a built-in Lightning cable so you don't need to remember to bring one with you (we've all done it, right?).
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.

Feeling the need for maximum power? The appropriately-named MAXOAK 50,000mAh Power Bank should be just what you need if you're lugging a stack of devices around with you and can't afford to let them run low. With 50,000mAh on tap it's the most powerful option listed here, and seriously versatile with six ports that should enable you to charge almost everything at once.
Sadly the big exception to the charging party is a MacBook, which could rule out this power bank for many creatives. However if you have a laptop from Fujitsu, Sony, Acer, Asus, IBM, Dell, HP, NEC, Samsung or Lenovo then you're good to go.
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. Be aware, though, that this is the heaviest model on our list, and one of the most expensive.
Let's be clear, the Omni 20 is going to overkill for most people looking for the best power bank. It's heavy and gives you a lot less power than you'd expect for its considerable price. That said, if you feel the need for a good-looking premium power bank that can charge loads of things at the same time, this could well be the option for you. It has a two each of USB-C and USB-A ports as well as offering wireless charging, and it also features an OLED display to let you know how much power's available and how fully charged your devices are.
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. And while it's a lot more expensive than most of the other power banks on our list, if you need to use your devices a lot the investment could pay off, by allowing you to keep going for longer.
For a basic budget alternative to the Omni 20 above, try the iMuto Ultra High Capacity portable charger. It weighs about the same and has just as much power on offer, but comes in at a fraction of the price.
Obviously it's not as slick as the Omni 20 and doesn't offer as many charging options, but it'll charge most phones about four times, so it's just the thing if you need to stay connected over a long weekend.
A solar power bank can be a good idea if you're going to be outdoors a lot, and, if you're not going completely off grid, it's great to be able to rely on being able to recharge your phone when you're away from civilisation. The kilponen Solar Power Bank 26800mAh offers an impressive capacity and will fit in a pocket easily. There's only two ports – both USB-A – but as long as that's not a problem, it's a competent device. The LED indicator system shows how much power you have left.
The best power banks: FAQ
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. And it's worth checking what sort of ports are on offer; USB-A ports will do the job but not every quickly, while if you can find a power bank with a USB-C PD port then you'll find your devices charge nice and quickly.
What's the best power bank brand?
We feel that Anker is often the best power bank brand, which is why the Anker PowerCore 20100 power bank tops our list above. With its big capacity, fast charging and excellent value, it's a no-brainer, unless you're looking for really high capacity or specific compatibility. There are a few devices the PowerCore 20100 won’t work with.
Mophie and Belkin are also great power bank brands, but you should be wary of brands that you've never heard of, particularly if the brand name reads like someone grabbed a handful of tiles out of a Scrabble bag and chucked them on a table. You'll find thousands of them on Amazon offering loads of power at a knockdown price, but while some of them might be genuine bargains, you're running a real risk of buying something that'll seriously under-deliver then fail on you in short order.
