I have a portable 40 AMP 220v EVSE charger from EVSEAdapters.com. It comes with a wall bracket for mounting on the wall, and has a NEMA 14-50 plug. The benefit of this charger is that you can set a timer and select an amperage rate between 12, 16, 24, 32, or 40A. This charger will also work at 120v. See the link above for details. It served me very well while I owned my Bolt. $250 shipped.

TESLA TAP IS SOLD. I also have an unused Tesla Tap Mini 40 amp. I purchased it for a long road trip but never used it.

I recently sold my 2021 Bolt, so I no longer have use for these. I'm happy to answer any questions you may have. My buying/selling feedback on eBay can be seen here.
