Review on Parkworld 885378 EV Adapter Cord | TT-30P to 14-50R (1.5FT) | EV/Tesla Use Only (NOT for RV) by Wesley Carreras

I just want to confirm to all Model 3 users that this will work perfectly for Tesla. This allowed me to connect to the RV outlet in the cabin we rented. Just make sure you set your charge boosters to 24A otherwise Tesla/UMC will still think it's a 50A socket. If you want to know why it's only for Tesla/EV, it works by typing Omit 120v and neutral to both -120 and +120 by 14-50. This adapter fools the UMC into thinking it only gets a 14-50 low voltage connection. If you connect this to something else it won't work as the voltage is half that.
