The Anker PowerCore Slim 10000 is a medium-sized power bank with 10,000mAh capacity, so should be able to charge your phone twice. But does it live up to its claimed capacity? And does it do this easily, quickly and efficiently? We sent it to our test lab to put this power bank through its paces. Read our full review to find out whether it delivered the goods.
