Official Adaptive Fast Charger Kit for Samsung Galaxy Tab E 8.0 Tablet with Micro USB 2.0 Cable. The Dual Voltage 9V and 5V 2.1A Fast Charging works best on supported models (your model may not support it, verify first) from 0 to 50% in about 30 minutes! If your version/model does not full support Adaptive Fast Charging, this will still charge at 5Volts using 2.1A and 15W, usually it stilll charges faster!
