Universal charger

After I finally had the camera Lumix DMC-FZ200 in hands, I noticed very quickly that the battery can only be charged in the external charger. This funktionier but only with Netztstrom (110-220V) and has no connection to other power sources. Since cameras are still used preferably on vacation and there from and is in no network available, the lack of low-voltage input is very short-sighted of Panasonic. Fortunately, creates Bundle Star with the here discussed charger remedy. It can handle all power sources used for this purpose in question: 5V (USB), 12V (car) and mains voltage. In particular, over the 5V input, I was very surprised, because the battery needs> 7.2 V for charging and a Erhöhuing the voltage is quite rare to find because electronically more complicated. The more astonished I was that loaded fast with USB cable, the battery. In summary, I am thrilled by the vision of designers and together with two batteries is really worth the money this charger.
A word about the battery: As far as I can tell so far is the remaining time display in the FZ200 (I was after reading the product description is not sure).
