Charge plugged and unplugged! During use as a wall charger, the internal battery recharges and is ready to provide power to your gadgets when away from outlets. Charge on the go, at the beach, on a boat, in the air - charge anywhere!
We bought this for a 2 week European vacation with a couple 8 hour flights. I plugged it in overnight and let my iPhone 4 discharge to 5%. I unplugged it from the wall and plugged it into my iPhone. It died with the iPhone at 70% charged. So you only get a 65% charge out of this $40 device. What exactly is the point of having 2 USB ports? So you can give a 32% charge to 2 devices? Worthless and a waste of money. We also bought a Yoobao that at least gave 1 full charge.
