Unfortunately, there is still equipment that can be loaded only by mini-USB. Battery packs and shutter glasses, for example. Therefore, I still had to keep the appropriate chargers, or at least the cable. Especially traveling very annoying. With this adapter, the problem is solved. Micro-USB chargers are standard today, even the latest version of the 8-inch Galaxy Tablet from Samsung is loaded. With this adapter, I can the Chargers from mobile phones and tablets at home and in the car for charging of said equipment, such as battery packs use. A real gain in comfort. The Eingnung for data connections I can not test, because I do not have appropriate hardware more.
