We explore the world of TT-30P aka 30amp RV plugs as there are many remote RV sites that only have this 30amp – 120V style outlet and most Tesla owners are NOT prepared to charge in them! While I was planning out a future trip from Prince George, BC to Whitehorse, Yukon, it became clear that the only way to get around the far north is to charge using RV campsites and many of those only provide 30amp service. Follow me through this video to find out what this style of plug looks like, what NOT to get, and what type of adapter would be required for this to work.
Part 2 showing a working solution can be found below. In part 2 of this series where we discuss the TT-30P outlet and charging with your EV, I had 2 options to pick from:
- TT-30 Adapter for Tesla Model S/X/3/Y Gen 2 – https://www.amazon.ca/gp/product/B07VB1JGQQ/
- AC WORKS EV Charging Adapter for Tesla Use (TT-30 RV 30A to Tesla) – https://www.amazon.ca/AC-WORKS-Charging-Adapter-Tesla/dp/B06XHDRBBT
I chose the first adapter because it automatically sets the max charge rate to 24 amps, which you would have to MAKE SURE you do manually if you get the second adapter. We can see that I got 3kw @ 24 amps or 12 km/hr charge rate and is a rough estimate of what you could expect at these 30 amp RV sites.
Using the Tesla Portable Wall Charger’s household 110V adapter you could expect 1kW @ 12 amps or 6km/hr (see example in this video: https://www.youtube.com/watch?v=3xBVQ4brwLI)
Another possible solution to improve your speed would be to use a TT-30P splitter to Nema 14-50 (if the campsite has dual plugs or if you have a long extension cord to pull a second line from another plug) which would allow for the faster 50 amp charging rates:
