Charge your tablet efficiently or two devices simultaneously with the Cellet TabletSmart Dual USB Home Charger. Featuring innovative TabletSmart chip technology, it detects most tablets for optimum charging; unlike some aftermarket chargers, they do not have the “wake up” to charge when the tablet battery is fully drained. With two USB ports, you use existing USB cables to charge two devices at the same time; if one device is connected it will receive 12W (2.4 amps) of power and if two devices are connected, each port will provide 6W (1.2 amps) of power. The built-in smart IC technology prevents your devices from overcurrent, overcharging and overheating and the compact size and folding prongs offers easy storage.
