Charging a Tesla at RV Parks with a NEMA TT-30 Adapter

When traveling across the U.S., Tesla owners often find themselves at RV parks or campgrounds where NEMA TT-30 outlets are the standard power source. These outlets are 120V, 30A connections designed for RVs, and with a Tesla NEMA TT-30 adapter, they can become a reliable charging solution for your EV.

A TT-30 outlet supplies 30 amps at 120 volts, but electrical code requires continuous loads like EV charging to be capped at 80%. That means a Tesla using a TT-30 adapter will charge at 24 amps maximum. In practical terms, this provides around 10–12 miles of range per hour. While slower than a 240V outlet such as a NEMA 14-50 or 6-50, it’s still perfectly adequate for overnight charging during road trips.

The main advantage of TT-30 charging is accessibility. RV parks are widespread and often allow EV drivers to plug in for a fee. For Tesla owners planning long-distance travel through rural areas, having a Tesla TT-30 adapter in your trunk ensures you can always find power—even when Superchargers are miles away.

It’s important, however, to use a UL-certified TT-30 adapter designed specifically for Tesla charging. Cheap or makeshift adapters may overheat or deliver the wrong signal to your Mobile Connector, creating safety risks. A proper adapter communicates the outlet type to your Tesla so it automatically limits current to safe levels.
