The quality is pretty good, however the screen is quite small, but once you hook it up to your PC the videos and still life are great. Do keep in mind though that the is no flashlight on here so filming in dark places is not an option.
If you're looking for a cord for this camera, it doesn't need one as the USB is built in.
If you're asking about a more general use AC-USB plug, you can find them just about anywhere. Try searching "usb charger" in Electronics department here at Amazon. Also, I thought "Belkin Mini Surge Protector Dual USB Charger" looked like a good buy.
