I was curious about that to so found this on Bolt forum
"OK, let's do that for 12 amps. 1.440 kW charge. 5.76 miles per hour of charge.
That's why level 2 is so important. 240V * 32A = 7.680 kW, for 30.72 miles per hour of charge."
120V Charging Limitations - Chevy Bolt EV Forum
So if you had a full charge start Monday 250 miles, end of day 140 left. 10+ hours at almost 6, call it 60 miles refueled a night. 210 Tuesday morning, 100 Tuesday night, 160 Wed morning, 50 Wed night, 110 Thur morning and your be sweating it out if you make it home.
Edit: I pulled the 250 miles from memory, not sure that's right. They also said 47 hours at 120/12a from dead to full.
