My review is from an external battery with 10000mAh capacity in the color combination white / neon green. The device serves as a handy cordless Reserve. I use it on the go to recharge my iPhone and can this so for a week full charge once a day. To keep the battery fully served its purpose throughout. What bothers me a little, are the weight (250 g) and the extent (13,5x7,5x1cm).
Caution: A power adapter or charger to charge the battery not included.
