My nikon d80 Camera Charger got lost in a mixup. Both of my batteries are dead, and my local camera shop wants 80$ For one! ( NO THANKS ) I have this cell phone charger, and you can attach a USB cord and plug the end that goes into the computer into the charger, and the end that goes into the product into the product. You plug it in and it charges it.. This works on cell phones but should I try it on my nikon d80? I want to take pictures tomorrow, but I dont want to ruin the camera.. Any advice?
