I bought the charger because the original unit of Sony offers no way to charge the battery in the car. This charger mr! Trade can be connected both to the household power supply as well as an automotive wiring (12V). After the order on Friday afternoon, I held it on Monday morning in his hands! But be careful! First came the disappointment that the battery obviously did not fit on the charger. However, that was my own fault, because I had overlooked the charger in the box. This is adapted to the battery and only needs to be pushed onto the lower part of the device before the battery then continues on. The manufacturer wants to avoid further questions, when the two parts would be assembled prior to delivery, but I also see one that I would have the complete package contents only need to look at before I try out the part.
