Thanks for that.
I found a few people who had tried these high-cap batteries. They were doing comparative tests, so what impressed them, impressed me.
Also the qi pad was new to me, this is a possibility for a design, but there are some outstanding problems that, IMO, mean that the absolute performance will not equal that of designs with an offboard transformer.
I think it'd be noisey, if powered by that, I was thinking purely for charging, it might allow for a smaller case.
