Was almost despair, if I really have to buy the expensive Sony battery charger (BC-TRN) for battery Sony NP-FG1 / NP-BG1 Sony HX9V my. But then I found this great part. Without the images on the back I would have understood but not so fast, how to use the battery pack correctly. The plastic pin located on the side but I have immediately used intuitively. It may in some batteries (particularly in the thin mobile phone batteries) have been coming to a little fumbling, but that is not worth mentioning.
The NP-BG1 Sony battery pack and the BP-4L battery of Nokia, I have so far charged 1x. Was very smooth. The time I have not stopped. In any case, you have saved real with this device. 1 charger for nearly all battery types. And when Ansmann certainly not at the wrong end. Ansmann are 3 year warranty on this device.
