I have a usb car-adapter and the output is 5v/ 850mah. Just wondering if it's safe for my new 3G Ipod touch? Thanks a ton- I've searched all over but can't find it. I think some that are sold are 5v/1amp which leads me to believe that mine would be safe. I actually plugged it in this morning on the way to work and it didn't smoke or anything, and the battery stayed full for the 1 hour car ride, but I just want to make sure before I risk my new little baby!
