Best power banks 2021: portable chargers to keep your gadgets going

All your portable gadgets have the same problem - limited battery life - so you could almost certainly do with one of the best power banks to help keep your devices going when you're away from a fixed power source. 

Whether you're looking to charge your phone, tablet, laptop, smartwatch, or other devices, there's a lot to consider before buying a power bank though. That includes how much capacity you need, how much you're willing to spend, and how slim or portable you'd like the device to be. You might even be tempted by a solar power bank if you're planning on being off the grid for a while. 

If you're just planning to use it to charge your phone every now and then, a super high capacity power bank won't be essential but if you want to charge your laptop or Nintendo Switch, you'll need a lot more juice.  More power typically ups the price and size so it's a balancing act to find the right power bank for you, even more so if you need to charge multiple devices at once. 

So, where do you begin? Luckily, we're here to help. We've arranged the best power banks according to the key things you might be looking for. That means everyday power banks, lightweight ones, slim ones, high capacity power banks, along with wireless devices and ones that can use solar power to recharge. It's possible to spend a little and a lot on these so we've also looked at different budgets. 

As a final note, what you won't find are any power banks from RavPower, Aukey or Mpow. These have all been removed from Amazon, seemingly due to the companies incentivizing people to write reviews by offering gift cards and the like. While these reviews might still be honest, the promise of money could spur people into writing overly positive and unrepresentative ones. 

So while you can still find power banks from these companies elsewhere, we can't recommend them on the basis of this business practice.

Best everyday power banks

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.

1. iMuto 20,000mah power bank

Affordable with most of what you need

Large capacity for price
Has a screen
Chunky design
Very heavy

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.

Big battery size
Fast charging for some
No Qualcomm Quick Charge

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. Look out for the fact it can get a touch hot during use.

3. Mophie Powerstation Wireless XL 10,000mAh power bank

Plenty of options with style too

Extensive port options
Wireless charging

Not the best of wireless charging options, the Mophie Powerstation Wireless XL 10,000mAh power bank is still worth considering as an everyday solution. It can charge two devices at once using both wired and wireless methods, with Lighting and USB-C ports an option too. Capable of dealing with almost anything you throw at it, it's a bit chunky and heavy but it does the job.

Ideally suited for iPhone users and smart too

Integrated Lightning cable
Great fabric design
Expensive for what it offers

The Mophie Powerstation Plus XL 10,000mAh power bank is ideally designed for iPhones and iPads thanks to its embedded Lightning cable. That means you can't lose it and you can't forget it either, saving you some time and effort. 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 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.

Best lightweight power banks

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.

1. Anker Astro E1 5,200mAh power bank

Incredibly small yet quite potent for the size

Very small design
Limited capacity
No Qualcomm Quick Charge support

The Anker Astro E1 5,200mAh power bank isn't going to be a long term solution but if your smartphone simply needs an electronic pep talk of sorts, this will do the job. It has a low capacity of 5,200mAh but that's enough to charge your smartphone almost twice or a tablet to about 70%. During a busy day at work, it can make all the difference but don't count on it long-term.

Sleek and lightweight with quick charging support

Quick Charge support
Thin as well as lightweight
Quick Charge only for one device

The OKZU 10,000mAh Battery Pack looks pretty sleek as well as lightweight. It has dual USB QC 3.0 ports which both support quick charging although you can only do so with one device at a time. Still, it's certainly useful and the 10,000mAh capacity means you won't run out of juice too soon either. Smaller than many phones, it's quite potent.

Best high capacity power banks

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.

It's a fairly bulky and heavy unit because of all those ports but that's a small price to pay for so much juice.

Stylish design
Good capacity

(Image credit: PowerOak)

6. PowerOak 50,000 mAh Power Bank

A powerhouse of a power bank

High capacity
Six output ports
Incredibly bulky

The PowerOak 50,000 mAh Power Bank isn't designed for tossing in your bag without thinking about it because it's huge. However, it packs in a huge 50,000mAh capacity so we'll forgive it. It also crams in six output ports with one aimed at laptops, one for digital cameras, two for smartphones and tablets, and another couple too for good measure. This is the power bank to take camping or off the grid, but you'll need to plan accordingly weight wise.

Best slim power banks

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.

It's very much a 'what you see is what you get' device that's ideal if you don't want to steal focus.

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.
