Is there a way to charge a sony handycam dcr-dvd108 with usb cord plugged into a wall or computer?
I don't know how you would plug a USB cable into a wall outlet. I wouldn't recommend trying. If your device is meant to be charged by way of a USB cable then that should work although I doubt a camera is such a device. Normal USB outlets will only pass 1/2 AMP of current and I doubt that's enough to charge a camera battery. I suggest contacting SONY.
I think your model can only charge the battery using a battery charger. Not quite sure if it'll allow the battery to charge while connected to the body like that, let alone through the USB port. I would contact Sony just to make sure.
