Official Quick Charge Kit for Huawei Ascend Mate7/7i/P8* with Micro USB 2.0 Cable! The Dual Voltage 9V and 5V 2.0A Quick charge 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 2.0A , usually it still charges faster! This Kit includes a full power USB to Micro USB 2.0 cable that allows you to charge via any or other USB power source if you aren't near a wall outlet. Quick Charge is new and if your model does not support it, results are NOT 100% guaranteed for this feature. This will charge, and in most cases, will charge faster than the original.
