Many cameras are now supplied without charger. Especially with video cameras, which have a comparatively high power consumption, a second battery is almost unverzichbar. To turn the camera does not always have to use a charger or an external charger is very useful. This can be operated at the outlet, as well as to 12V here. The battery charge is technically a bit smaller than the original (660mAh to 800mAh), but this is OK for the price. The charger is a rather cheap plastic case with a fairly difficult to identify LED, which indicates whether the battery is being charged or not. That's also the only way to detect whether the battery is inserted correctly or not. Mechanical snap he does namely. Overall, the package is worth its price, at the cheap build quality are 5 star yet not in it!
