You can install a 240 volt 20A outlet. Then use an adapter to convert to a standard 120 outlet and plug the level 1 plug on the OEM EVSE into that. You will get level 1 charging at 12 amps/240 volts instead of 120 volts, so twice as fast as level 1 but about 65% slower than level 2 32 amps. That will replace about 10 miles per hour or about100 miles overnight (10 hours) so if you drive less than 700 miles per week that should be adequate.

It is important to note that many NEMA 14-50 to NEMA 5-15 adapters will only provide 120V. You need one that connects both hot wires to the hot and neutral pins of the 5-15 outlet in order to get 240V charging. But DON’T plug an any 120V appliances into this adapter!

The adapters you typically find for campgrounds will just pass 120V to the outlet.
Good point.

I purchased a 2022 Chevrolet Bolt the first of July, 2022. It took until the end of October, 2023 to finally get my 240 Volt receptacle installed. The receptacle was tested by the electrician who installed it and it tested out correctly. When I tried to charge my battery, it would only charge at the lower rate. I have tried to get the Watson Dealership, Tucson, Arizona to return my calls and e-mails, to no avail. I have lodged a complaint with the GMC customer service, but have received no reply. What should I do?
I am pretty sure that there is only one charge rate for the level 2 side of the OEM charger and that is 32 amps.
What is the circuit breaker amps for the 240 outlet?
Which EVSE are you using?
