Fayette, Michigan
40 public stations listing NEMA TT-30 across 11 states. 12 are open around the clock.

NEMA TT-30 is a 120-volt, 30-amp outlet used by older travel trailers. It is the slowest outlet type in the directory, and it needs a compatible portable EVSE.
The TT-30 shape is not the same as a household 5-15 outlet and it is not a 240-volt RV outlet. A standard EV charging cable will not fit without an adapter, and adapters must be rated for continuous EV use.
Expect a slow top-up rather than a full charge: this is a listing for an overnight stop where the car can stay parked. The directory includes it because some RV parks and campgrounds offer it to EV drivers.
What the label means
TT-30 is AC Level 1 charging. It is not a fast charger and is not the same as a NEMA 14-50 outlet.
The states with the most stations listing NEMA TT-30. Each link opens that state's page; the directory keeps the connector filter for a narrower view.
The cities where these stations cluster. A link opens the city's own guide where one exists, otherwise the directory around that city.
NEMA TT-30 stations by place type
Counts are stations that list NEMA TT-30, not plugs. One station can carry several connector types, so a station can appear here and in another connector's count. Prices are the networks' own per-kWh tariffs and can change by time of day. An outlet count is the site's, not a count of charging stalls, so this page quotes stations rather than stalls. Counts from the directory data of October 2026.

EVDIR lists 40 public stations with NEMA TT-30 across 11 states and 37 cities. The NEMA TT-30 connection is AC, not DC fast. A station can still list another connector for faster charging.

EVs with a TT-30-compatible portable EVSE. Slow charging at an RV site. The connector a car accepts is fixed by its inlet; an adapter may be needed for a different standard, and support varies by vehicle and station.
The networks at these stations do not publish a per-kWh tariff in this directory; some bill per minute or per session instead.
No label guarantees a rate. 120 V, 30 A; the station and the vehicle negotiate the actual charge. Check the station's peak power in the directory before relying on it for a quick stop.
