I bought this charger several months ago and thought it was another rubbish I had ever got as it could not charge my Galaxy Tab nor my Blackberry 9700. It can charge my other phone and a bluetooth earphone though.

However yesterday I found it could charge an Ipad2. Also I found that many other chargers and computer USB could not charge the Galaxy Tab when it was turned on but could be charged when off. So I guess it was not the problem of the charger, it might be some interal setting inside the Galaxy Tab.

The device claims to have a 2A out on both USB ports, but either Duragadget failed to set the proper resistances to ID the outputs to the Tab as a 2A max draw or it simply isn't putting out 2A, as the Galaxy Tab will only recognize it as a USB trickle-charge (charging icon will have a red X, and it thinks it's been connected to a USB port and will offer to turn on mass storage mode). Technically, the Galaxy Tab will still gain charge in this mode, at least if it's powered off, but not quickly, as a 2A charger should. In that half-charging mode, it may even slightly drain even when plugged in, depending on CPU and screen draw.
