When shopping for tablets, it seems the specifications rarely if ever state whether they support Qi charging or not. This is a primary requirement as I'm getting it for someone suffering from a movement disorder who therefore cannot plug in the micro-USB. Do specifications overlook Qi charging because it isn't so much a feature of the tablets as a feature of the battery and they expect you to get a Qi capable battery? Is there a site somewhere that specializes in telling which devices support Qi charging? PS: I am having to return a Nexus 7 second generation (2013) I purchased because it apparently was "refurbished" with a battery without a Qi coil.
