Those chinese cables are to be avoided at all costs. Nasty things can happen with them and they can damage your tablet, or your PC. Normally I'm all for 3rd party parts, as they save you money, but not in this case.

If you want a nokia usb charger cheap, go to overstock.com. That's where I find all my extra stuff cheap. If it ain't there, it's either too new, or selling too well.
