The number of sockets and the length of the cable usually decide it, but these days it is also worth looking at whether the strip has USB-A and USB-C ports for charging a phone. On the basic extension cords from Hama and Brennenstuhl the lengths run from one and a half metres to five, and LINDY's 1.4-metre strips come with three or six sockets. Hoco's and BlitzWolf's models add fast-charging ports alongside the AC sockets, and if a computer or a television will share the same cord, choose a version with surge protection.
