I am ordering a few of the banggood mag chargers. Hoping they work better than my experiments with first Touchstone and then Qi inductive charging. Both pad chargers require not only good contact but also either soldering in with a charge manager board or very careful shorting of the USB data pins and having a wonky ribbon cable to the USB port
Simple is best, a mag cable seems smarter than inductive receiver pads if I it lasts and makes contact.
Only problem I see is not loosing the adapter plug when I use a USB flash drive to transfer files form my N900.
