I can report back that the TEMAI wireless charging pad works great with the mini, both vertically and horizontally, and it’s nice it only takes up one outlet (Jeda took up two, and did not charge the mini vertically without additional items put in to prop it up). I tried to charge some wireless earbuds on the other side of the TEMAI pad at the same time, and realize I’ll have to prop them up with a credit card sized spacer. Not a big deal. More important I can finally charge my phone wirelessly.
I tried finding the sweet spot on the Tesla pad, but never quite found it. Another thing to note is that after over a week, no response from Jeda on my requests to return their wireless pad that misleadingly says in their web site works with the mini. Hope I didn’t throw away $75 for nothing.
Thanks to everyone here for their help!
