Where I can buy battery charger Nikon d3100 in charlottenborg, Berlin?

I forgot my battery charger and I need buy one here in as fast as I can but I don't know where find a place to buy a battery charger of Nikon d3100 here in berlin. Could you help me?

Take the subway to "Wilmersdorfer Str", there's a pedestrian shopping area in that street. They have one of these large electronics shops, I can't remember which one, though - Media Markt or Saturn Hansa. Anyway, they are all the same. Ask for your charger there, and if they don't have it - you can either try to find a specialized photo shop, or simply buy a cheap digital camera that you sell when you get back, keep as a spare or give as a present to any children in your family.

By the way - there are cameras that don't use special batteries that you have to charge with the right kind of charger, but some use normal AA batteries. Of course you can use rechargeable AA batteries, but if your battery goes flat in the middle of an interesting day trip, all you need is some standard AA batteries from the next supermarket and you can go on taking photos. My camera is like that, it's a Canon Power Shot A590 and I'm very satisfied with it, but I've had it for two years or so now, so I'm not sure if you can still find it.
