This is my 2.Battery of Patona and it works just like the other fine at the Panasonic SD99. The charger is in my view perfectly acceptable, loading it is only slightly warm. Of course it takes some time until the battery is charged, but the battery can only too good kommen.Eine LED illuminates during charging red and then switches to green when the battery is fully charged. If you want to download faster, you should just do in the camera itself. I also like that you have near the power cord and the ability to load via USB cable (included adapter for the car). The instructions are kept short in German and English, the unit makes me not cheap impression. I hope in any case that I long may thus charge the batteries for my camera. For those who are interested in it, here briefly the technical data which are on the rear panel:
Input: AC 100V - 240V 50/60 Hz 150mA Max DC 12V 500mA Max DC 5V 1000mA Max Output: 350mA DC4,2V
