Festival season is hereand we know you’ve already packed your sun screen, tent and water bottle. But there’s one more essential piece of kit you can’t do without: a portable power bank to keep your phone topped up. If you’ve ever had yours run out of juice right before that crucial Insta-worthy moment or while searching for your friends, you’ll know how important it is to keep the battery full. The best portable chargers can refuel your phone at least one or two times over, and will be small and lightweight enough to carry around all day.
Here’s our pick of the best portable chargers in 2022:
There are loads of power banks on the market, and we just don’t think it’s worth going with a no-name brand when there may be a risk of overheating or charging failure involved. For our list of the best portable chargers, we focused on trusted brands and reliability. We tried out the best models by powering up a range of different phones (including Apple’s iPhone SEXRand 13 min, and the Google Pixel 6) and timing how long they took to get the handsets back to half full. The picks in our list are a mix of our hands-on tests and expert recommendations.
What does the mAh mean on a power bank?
You’ve probably seen this alongside any portable charger online. We’ll keep the techy jargon to a minimum and just explain that the number of mAh or “milliamp-hours” refers to the capacity of the battery. Larger numbers mean more power, and that means more recharges for your phone.
What is the best capacity for a power bank?
We’d steer clear of anything under 5,000mAh (or 5K) as these smaller batteries won’t even recharge your phone once. 5K is good for about one full charge for most smartphones, 10K or 10,000mAh can recharge most newer phones about two times, while a chunkier 20K power bank can deliver four or five recharges, depending on which phone you have.
