This 10,000mAh Slim Power Bank is the kind of everyday essential you end up carrying everywhere once you’ve got one. It’s compact enough to chuck in a backpack, handbag, or glovebox, but still has enough juice to save your phone when it’s dying at the worst possible time. The digital display is handy because you can actually see how much charge is left, instead of guessing from little dots. Great for commutes, festivals, camping trips, long days out, or anyone who lives on their phone. It’s also a super practical gift because everyone needs it, and no one thinks to buy it for themselves. If you want a gift that’s useful from day one, this is a winner.
