Perfect travel gadget. Each USB port delivers full power and is compatible with smart chargers. My Galaxy Pad fully charges in a few hours compared to an overnight charge when connected to my Macbook. Especially for international travel; You only need a plug adapter, and you don't have to worry about USB plug adapters because they are not needed. You may think that not all USB ports are necessary. I regularly use three to four: iPhone, Galaxy Pad, headphones and USB battery. Additional ports come in handy when traveling with children. And I connect my Macbook to the 110V plug at the top. The only improvement I would recommend the manufacturer is to redesign the case so that the power cord can be wrapped around the outside of the case.
