Our verdict

Wall socket or no wall socket, that is the whole decision. Anker's 20W PowerPort III cube costs £10.99 at the time of writing, takes an iPhone to 50% in under half an hour, and holds a superb 4.7 from 15,000 reviews in a genuinely tiny package. INIU's 20,000mAh power bank is £22.41, rated 4.6 by 31,000 buyers, and carries several full charges with 22.5W output, working where sockets do not, on trains, festivals and long-haul flights. At home the Anker is the better tool and half the price. Away from home it can do precisely nothing, which is where the INIU earns its keep.
