We live in Austin and decided to drive to Houston. We were at 178 Miles (Houston is 140 Miles) we just made it with 30 Miles to spare. We decided to charge using a EVGo DC Charger. It stopped at 170 Miles and an hour of charging. We would like to get back to Austin with 220 Miles starting off. Can we just charge at my sisters house using my Bolt charging cord to fill it up? It’s not on hilltop option and it was at 12 instead of 4. At the house I’m assuming we can just use 4 amps?
