Adding to others: RV hookups. There are tons of these around, some further away from civilization than you’d think. They provide 220 hookups, which is plenty to get you charged up overnight.
- LeifCarrotson 6y agoMost RV campsites are set up for 30A at 120V over a NEMA TT-30R receptacle. Three pins, looks like a typical cord but the blades are rotated outwards by degrees: https://en.wikipedia.org/wiki/NEMA_connector#NEMA_TT-30 https://en.wikipedia.org/wiki/NEMA_connector#NEMA_TT-30 Only the really, really big ones are 240V split-phase with a NEMA 14-50R receptacle. It's a 4-pin connector, with an additional neutral blade, but it's not a twist-lock: https://en.wikipedia.org/wiki/NEMA_connector#NEMA_14 https://en.wikipedia.org/wiki/NEMA_connector#NEMA_14 It's not likely to break anything or hurt anyone if you know what you're doing, but with the ridiculous number of variations and non-standard wiring you'll find out there, be sure you do know what you're doing!
- cptskippy 6y agoI haven't seen this with any other EV maker's chargers but Tesla sells an adapter kit for it's 2nd Gen Chargers. They have a 14-50 but there isn't a TT-30R however they have a 5-20 which can be mated to 5-30 with a passive adapter. Not ideal but better than nothing.
- Kirby64 5y agoProper way to use a TT-30R is to use a 14-30 or 6-30 and then adapt to the TT-30R. The Tesla adapters do not care what the voltage applied is. You can happily use a NEMA 14-50 adapter at 120V-50A, but it's kind of a stupid idea since power is so much lower.
- cptskippy 5y agoThat's cool, I didn't know that. I assumed the dongle somehow indicated to the charger what to expect.
