I want to get a new cable used to charge my ASUS TF301 tablet. One end has a usb connector that goes into the part that plug into an electrical outlet, and the other end plugs into the tablet itself. Can someone direct me please to a website to order this from? I have looked on ebay but had more questions arise and wasn't sure it was even there. Went to the ASUS website and it was no help, either. Thank you!
