50 Hz 220V charger and 12V DC, very useful if you are a fada photo, and you have a power hungry device like in my case. I needed two good batteries and frequently do not melt a day of traveling! The battery supplied with the charger is frankly better than it original, it goes without bp (which is normal). Small BMOL all if it is not too heavy, a bit bulky. for my part, I leave it in the glove box of my car.
