I bought one of these a few weeks ago as I was tired of having multiple transformers for each device. It does a competent job of charging my iPad Air, Verizon wifi hotspot, iPhone, Seagate wireless drive and other devices in various combinations. I use it instead of multiple power bricks at home and on trips.
