»What I think is a design genius is the retractable cable on the Sandberg Charger PD65W. The display is clear and has a nice enough contrast to be easy to read. The numbers are not that big so not everyone can see them from a distance, but at the same time there are indicators of how much you are using the full bandwidth of the charging socket, so you can get an impression even if the charger is far away from the socket. Charger PD65W Display + Cable is definitely worth considering as a travel adapter for those of you who would rather charge multiple devices from the same charger without having to lug around more.«
