Usually I carry always 2 fully charged batteries with me around ... an in camera and one in a pocket. Once a battery is empty, it is replaced and reloaded at home. If you want now, however, invite these 2 battery, one would have - without an extra charger as Baxxtar - remove the battery from the device and change to the empty and recharge.
You can tell already ... very umpraktisch.
Original charger?
Genuine accessories was a little "overpriced" me 50Euro at a price of ca.400Euro camera.
So I picked up the Baxxtar because it promised me the best price performance.
Delivery was fast and dependable.
The original battery fitted well into the charging shell which has to be supplied separately to Baxxtar PSU and there plugged easily.
A red LED indicates when the battery is dead ... and changes to green when the battery is charged.
Have been two Baxxtar chargers (for my Canon 70D I needed even a) and have done so far with two very good similar experiences.
Charging Time: The charger has an output of 600 mA and the battery has a capacity of 1250mAh, so that the charging time is about 2 hours with a completely discharged battery.. Now I have no comparison to the charging time in the camera, as I had informed me in advance and immediately the charger was ordered.
From me a strong buy recommendation.
