Since I've had good experiences when it comes to battery batteries Ansmann, I use the version with Ansmann 2850mAh for Bike Lights and my Nikon Speedlight, I wanted to have in the house even when Ansmann charger again.
Purchase incentives were for me the brand, the single channel control, the design, the color, the direct plug into the socket (no cables and no bulky AC adapter) and of course the 0-Watt power consumption (from 1 hour after the last battery is full) , This only applies to operation on normal sockets. In the car (with the car charger cable) there is no such Zero-Watt function. The printer does then as long as power from the electrical system until the plug is pulled out of the cigarette lighter.
Once you have plugged the device into the socket, press the "Start" button in the top left for 2 seconds: The charging starts. Device and battery batteries are naturally warm, but definitely not hot.
It is especially nice that the black part of the device is made of aluminum. Looks nice and feels nice to.
The meaning of the control lights is explained in both the enclosed booklet, as well as on the rear panel. One does not necessarily cancel the manual so.
