k4 rear contact pins charging?
Hi, does anyone know if the two rear contact pins on a k4 can be used to charge the device?
I have picture frames using kindles, but the usb socket is in an awkward place for using in frames. I note that there are 2 contact pins on the back - has anyone used these to charge a kindle?
My understanding is that these are used for supplying power to lights etc
Thanks
