Need Adapter for 240V Outlet
I just purchased a 2017 Chevy Volt LT and I am trying to learn about charging in my garage. The outlet in my garage is a standard 110 volt, but I have a 240 volt outlet (10-30R, 3-prongs) for my dryer that is just inside the house right next to the garage, so a 20-foot cable will reach it easily. I have attached a picture of my dryer outlet here.
I've been reading the forums about using the EVSE that comes standard with the car and plugging it into a 240-volt (dryer) outlet using an adapter for faster charging.
My question is about the adapter. I read some postings from three years ago that said you cannot simply buy this adapter. Some people in the Volt forums were apparently making their own adapters. Is it still the case that I cannot simply buy an adapter at Home Depot or somewhere like that? I found one adapter at Home Depot that seems to "almost" suit my purpose, but it has 4-prongs rather than the 3-prong plug I need. Even if I can find a 3-prong adapter, I don't know if this will serve my purpose. It looks like it might "downgrade" the 240-volt outlet to 110-volt power, and that's not what I'm trying to do. Please excuse my terminology. I am a novice at electrical issues, obviously.
I would like to get an adapter rather than pay $395 at Clipper Creek for their 240V EVSE. Please let me know if I can purchase an adapter at any retail outlet or perhaps through someone on this forum.
Thank you, in advance, for your help.
