It is an excellent solution. I went a different way and bought a ClipperCreek 40 Amps, Level 2, 240 Volts, HCS-D50P Dual EV Charger NEMA 6-50 Plug, Up to 38 Miles per Hour of Charge, 2x25 Ft Cables, Indoor/Outdoor Use, from Amazon. It is still using your original single outlet, but will charge 2 cars at once. It is much more expense at about $1,700, but doesn't require adding an outlet. It works flawlessly also, and has choices as to the plug type.
