re. the grip charging, just press the tiny little button next to the row of leds for about 5 seconds and that toggles the "charging" feature on or off
Thanks!
Confirmed; called home and asked my wife to try it. Now I have an extra choice.
OTOH, the wireless charging combo kept working well this morning. I went to bed and left YouTube videos running while on the charger. The concerns were heat and whether it would keep charging along the way (current). Happily, heat stayed acceptable and the darn thing charged, despite a draw on a card that has a low amp rating. So, Wi-fi + video streaming + charging still left slower but useful charging at about 1% per 5 minutes or so...roughly clocked for now.
Which, taken with your own experience with a similarly-rated card, may mean that 700mA is the sweet spot as far a power and heat. Thanks to your earlier link to the already discontinued Amazon UK version, I had decided to enlarge their photos to see if the power rating could be found. Big pixels and all, it seemed to be lower in amps than anything out there. Since it worked for you, I looked for something along those lines also. Bingo! Tks.
