My charge from last night on a 30A charger (7.2 kW at 240V).
This is why I'm always harping on the "stop installing giant charger circuits" thing! Even this is a luxury - I only charge about weekly or if I make a long trip.
For USians, a 10 gauge run of wiring will deliver 5 kW sustained. You'll only ever think that's slow if you drive a TON and/or have a really big vehicle.
Especially if you're thinking of DIYing an install, 10 gauge is so much easier to deal with.

I wonder what CO sensor manufacturers say? Local fire department told me a decade ago that CO sensors lose sensitivity to the gas by exposure. Putting one by a vehicle exhaust pipe to see if it worked was a bad idea & meant that a replacement was needed.
