So my OEM EVSE has been collecting dust for my 2018 Volt because I purchased the dedicated L2 from day one and only used that. What has been annoying about it was that every day I went to work I had to open the garage door (Volt Sleeps Outside) unplug the L2, roll it up and take it to work. Setup at work and then take down and setup at home again. Not the end of the world but is annoying at 4am leaving to work, lol. After reading all the info from this forum about doing it I did and it was 100% successful. So now I keep the OEM at work with the adapter and leave my dedicated L2 at home since I need faster charging at home. Bought an RV 30amp cord that had the nema 5-15 receptacle already part of it and just hacked off the RV end and added a Nema L6-20 plug (that's what my home and work outlets are). Came out to just over 18 bucks and only took me 10 minutes to make. So glad you guys share so much info on here for others to do things like this.
