The product received is not the same as the photo. This is a battery of 1000 mAh. Unwrapped produced and supported by a USB socket after charging the battery, the power will therefore cut the risk of overheating or otherwise. Installation in the board without difficulty. The board works perfectly. Battery quickly loses a load bar but after more than 4 hours of operation, it still lacks that a bar. So proper autonomy, to see to wear when the battery will be several charges and discharges to his credit. The cable is long enough to play while charging. Finally, satisfied with my purchase.
