Since we’re on the topic of charging solutions, if you go the NEMA 14-50 route, please get a QUALITY 14-50 receptacle. This is critically important if you’ll be using the included mobile charger and plan on carrying the charger and the 14-50 adapter with you.
All NEMA 14-50 receptacles you find at your local home improvement stores for $10 are not intended for continuous plugging and unplugging. Many receptacles are made for household appliances where you plug them in, and that’s it until the unit dies in 10 years. Most will use a single screw-down design, which places pressure on one side of the wiring instead of the more expensive clamp-down design, which applies equal pressure on all sides of the wiring.
Over time, and I’m talking months, the cheaper receptacle's contacts loosen, which leads to a poor connection with the plug and a rapid increase in heat and can cause a fire. If you’re installing new work, you’ll likely see and smell the components and catch them in time to replace them. If you’re installing in old work (e.g., existing drywall), it’s much more likely that you won’t catch it until you see damage to the front of the receptacle, which means the back of the receptacle is already trashed.
Spend the time, and money, to get a higher quality receptacle that is intended for repeated use. I personally like the
Hubbell and it supports copper wiring only.
That particular Hubbell 14-50R is rated for 50 amps, so your chosen charger will draw a maximum of 40A, which will net you somewhere in the neighborhood of 33-36 mph.
