Tesla's wireless pad is basically the same price as the Nomad pad (one wonders if they might even be buying them from Nomad or some other manufacturer that already makes and sells these)?
I really love my nomad charger. It was worth the price for me, but I have not used the TapTes one. I have not tested charging speed etc, as that really wasnt important to me. What was important, was that my phone not get drained while listening to bluetooth music in the car, and that the phone "fit" and "stay put" in its spot when placed there.
