The big advantage with this Apple iPhone 5 Samsung Galaxy iPad power charger is two USB ports so you can charge both phone and pad at the same time. Ok so as a charger goes it does its job however, a MTO-2 USB cable would be given freely with this battery. The large capacity of Li-ion battery is 10000mAh, as it can recycle charge over 1000 times. Easy to take traveling and no problems with the current cords I own. Recommend this smartphone power charger battery for business man.
