However, a weak point of the two retaining lugs made of plastic, which are to hold the battery. (Are on the product photo can not be seen, because the photo shows the charger with any other charger.) They are both canceled at the first flight and light load. While this affects the charging function per se is not, but the battery is no longer held in the charging cradle. As long as the charger is still on the table, that's not so bad, because then the battery will be saying it. When you load in the car while driving, but I had the batteries dannn mooring with a rubber band, so that they remain in the charger. Not so great, fiddly and bad when you just ready no fitting rubber band, adhesive tape or the like.
Apart from that, the charger is very good and works just as opposed to the Nikon-original even at 12 volts and can also load the mobile phone or other devices.
