Yes, I knew that I could adapt the oem charger when I ordered the full-up level 2 evse. It has 3 different amperage settings; I’ll use the lower one now, but can switch to higher level for next car in 3 years 
If you are near Lawrenceville, there’s a very good Chevy dealer there - Ciocca Motors at QuakerBridge Mall - where I leased mine.Welcome! I'm a little South of you, but if you have a good dealer in your area let me know. I'll take a short drive for a dealership that has good Volt support.
