At the moment, I'm WFH -- charging at 32A lets me utilize my solar panels instead of selling the energy to the power company at a discount and then buying it back at full price. It's also a bit more efficient, since the car's electronics consume 300W continuous during the charging process, which means shorter charging times use less total power.

But as I mentioned in my comment way above, 120V12A works, but 240V32A is notably more convenient.
