Curious that the product description does not tell you the power output specification for this charger. The reason is that the printing on the device says 750mA, presumably split between the 2 USB ports. Compare that to a modern smartphone charger that is at least 1000mA for only one port. This Motorola charger will charge your phone eventually, but really really slowly. That maybe OK if you can let it charge all night (at least 8 hours). Don't bother if you need a fast charge at an airport or coffee shop. And don't even think of using this with a tablet. Tablet chargers are usually 2000mA or more and those still take a while to charge up.
