Many people, including me, have them in their garages. They were used for table saws, compressors, welders or small air conditioners/heaters like you find in many hotel rooms.
Where would a 6-15 (or 6-20) outlet be found out in the wild?
Well, I'm thrilled that Tesla is bringing out new charging adapters. But the 6-15 is a very odd choice. I've seen 6-20 and 6-30 in the wild (air conditioners in motels, for instance), but a 6-15?? I mean, it doesn't even show up on the list of plugs people charge from when I do my surveys every 6 months or so.

Actually, it's an L6-20, a locking 6-20 receptacle.
Oh yeah, I did misread that. That does kind of illustrate the point, too. L6-20 and L6-30 are actually fairly common. There is an L6-30 in the wall of the cafeteria where I work. I think some of the industrial vacuums or something plug into them.
It's safer to use their 5-20R to 6-20P adapter. Use the UMC 5-20 adapter with it, and you don't have to manually turn done the amps as you would with the 14-50 adapter on the UMC. That's why I suggested evseadapters.com make this one.
See my post 17 above. The UMC might not reach the car if plugged into the hotel room outlet, but it will with this 5-20R to 6-20P extension cord.I think I just wet myself
I have been waiting forever for something like this to plug into the side of my quick220 box
Not to mention damn near every single motel in the country uses this for their HVAC units. Back the car up to the door, run the cord to the car and you are all set for a decent overnight charge.
