There really is nothing worse than being out-and-about and watching the remaining battery from your phone, Switch or other device disappear completely. But you'll never have to experience this problem now that you can get an Anker power bank for less than £20.
For today only, Amazon UK is running a deal on a range of Anker chargers and more. The best of the lot, though, is the Anker PowerCore 15000 Redux for £18.99.
It has enough capacity to recharge an iPhone X or Galaxy S9 almost four times. Or you can use it to refill your Nintendo Switch at least twice off a single charge. Not bad for something that'll very easily slip into your bag or back pocket! Plus, there are two ports to charge two devices at once, while you can also activate the trickle-charge mode for smaller devices such as earphones and earbuds.
