Power Banks & Portable Chargers That Keep Up

A power bank is the sort of thing you ignore until your phone dies at 4pm, and then it's the most important object you own. The good news is this is a competitive, cheap category where £17 buys something genuinely useful. Two questions sort out most people. How much charge do you want (a 10000mAh pack tops up a phone once or twice; a 27000mAh brick does a weekend or a whole family day out), and how fast (look for 20W or higher, and USB-C, if you hate waiting). INIU and Charmast keep showing up here, and the built-in-cable models save you the eternal hunt for a spare lead.

Common questions

What size power bank should I get?

For daily top-ups, a 10000mAh pack is small, light and enough for a full recharge or two. For travel, festivals or charging a couple of phones, step up to 20000mAh or more. Bigger isn't automatically better, since capacity means weight.

Can I take a power bank on a plane?

In hand luggage, yes, and most of these sit under the usual 100Wh airline limit. Never pack one in checked baggage. Rules vary by airline, so a quick check before you fly is worth it.
