I bought this battery after being enchanted by a first battery purchased from the same manufacturer Anker. The device is very nice and perfectly functional. Why a flat? Because, little add-on a priori interesting, the battery is equipped with a high power diode which allows it to also serve the flashlight. This lighting is activated by pressing a large button front of the unit. Now this large button is easily accessible if it happens that the lamp is activated when the battery is in my pocket or my backpack. It then discharges unexpectedly. Here, the best was the enemy of good. Superb camera though. Thank you.
