I got one of the first Chevy Volts in the DC area in 2012 and thanks to the Dept. of Energy got a free Blink 220 volt charger. I tried charging an M3 with an adapter a couple months ago overnight and it worked fine - full charge. Now that I've just taken deliver of my new M3+ I'm charging again (because the dealer didn't have the courtesy to deliver fully charged - it was only 39%). But here's the question. I believe the Blink is a 32amp charger. It is connected to a 220 V outlet with a 40amp breaker. So when I first started charging the display read 32 amps. Then it did a software update and stopped charging. When it finished, and resumed charging it was only at 24amps. What's up? Also, could I be charging at 40 amps if I just plugged into the wall outlet using an appropriate Tesla adapter?
