Do you literally carry a circuit breaker with a NEMA 14-50 attached?
Yup, it was the original NEMA 14 plug I used until I received the HPWC, then I made it into a portable outlet that i can tap into a 30 or 50 amp circuit breaker in a panel.
I do carry a GE and a SquareD 50 amp breaker, which fits most newer panels, but if not compatible just use an existing breaker not being used, like a stove or HVAC unit.
When visiting family not living near a Supercharger, or in a state where none exists, it really helps to keep charged while visiting, plus allows for a full charge prior to leaving.
Admittedly, you have to be comfortable with working with a live and open breaker panel, breakers, 220v, etc
Plus, your family has to trust that you know what your doing, and you will not cause any damage, fires, etc. So far my Hot Springs family trust me..
Alternatives include finding a fee-based charging station, preferably with a Chademo adapter (nowhere in Ar I found), "stealing" electrons from a hotel with a Tesla charger you are not staying at (H.Inn Airport L.R. - actually offered $$, but was gifted time), or go to the Burger 21 under construction owned by very cool Tesla owner.
Alas, in a month or so it's a moot point, once the most-waited-for SC opens in L.R.
Easy steps
1) Remove Panel Cover (4-6 screws)
2) Turn off individual breaker, remove from panel
3) Loosen existing load wires with screwdriver, remove
4) Insert NEMA plug load wires, tighten, replace fuse in box (keep breaker turned off)
5) Attach Common to proper connection (actually may not be required)
6) Attach ground to proper connection
7) Turn on breaker
8) Plug in Tesla charging cable, look for green light (if red, something ain't right, possibly house not grounded properly - actually happened)
9) Insert not charging port, charge away.
