6 amps? Would that even be worth it?
When my bolt trickle charger drops to 8 amps I get quite annoyed!
I just plugged some numbers into this website. Assuming a Bolt at 20% to 80%, it would take 3 days to charge. As opposed to about 2 with 8 amps.
But if you’re charging exclusively with solar, and assuming 12 hours of sunlight, it would take 6 days.
I think having a way to charge the car off solar panels is going go become part of everyone's normal emergency kit in the future.
They keep getting cheaper, portable battery generators are getting cheaper and people are buying them to take camping or keep a fridge going for a short period. It's like the step between now, and everyone having a grid connected solar/home battery.
But with a couple portable solar panels and a portable battery, you'll be able to slowly power your car in an emergency. Might be slow, but it's better than no gas at all.
I didn't want to go into too much detail since it's tangential to EVs, but I have an off-the-grid solar system and have found in the spring and fall, with no A/C on, it would be nice to dump some excess into the car, but at 240V.
This was all before I signed up for a "free weekend" plan, so the EV charges for <5¢/kWh. I'm still learning how to balance all the variables.
So there are dual-voltage EV chargers, notably the Chevy bolt charger and Tesla charger (I think). You need adapters for them though.
I think Clipper Creek might make one as well, but not sure.
Edit - found this, would work. https://store.evsolutions.com/mobile/webasto-go---dual-voltage-portable-cordset-p124.aspx
Or an Amazing-E lower amp 240v L2 charger: https://enphase.com/store/ev-chargers/clippercreek-ev-chargers/amazinge-ev-charger-nema-14-30-plug-16
