What Adapters Do You Need to Charge Your EV at a Campground?
The outlets at a campground are not the same as the ones in your garage. Different plugs, different voltages, different connectors. Sorting out which adapters you actually need is not complicated, but buying the wrong one can leave you stranded or, worse, damage your charging equipment.
Two Sides of the Adapter Equation
When you charge at a campground, there are two connections to think about. One is between the wall outlet and your EVSE (the portable charger). The other is between the EVSE and your car. These are separate problems with separate adapters.
The wall side is about outlet types: NEMA 14-50, TT-30, and standard household plugs. The car side is about connector standards: NACS (Tesla and newer EVs) and J1772 (most non-Tesla EVs made before 2025). Getting both sides right is the whole game.
Campground Outlet Types
RV park power pedestals typically offer three outlet types. Here is what you are looking at and what each one means for your EV.
| Outlet | Voltage | Max Amps | Plug Shape | EV Charging Speed |
|---|---|---|---|---|
| NEMA 14-50 | 240V | 50A | 4-prong (two angled, one L, one round) | 25 to 35 miles/hour |
| NEMA TT-30 | 120V | 30A | 3-prong (one angled, one straight, one round) | 8 to 11 miles/hour |
| NEMA 5-15 / 5-20 | 120V | 15 or 20A | Standard household | 3 to 5 miles/hour |
EV Connector Standards
On the car side, North America is in the middle of a transition. For years, there were two standards. Now they are converging, but the installed base is still split.
- NACS (North American Charging Standard, also called J3400): Tesla's connector, now adopted by most major automakers. All Teslas use it. Starting with 2025 and 2026 models, Rivian, Ford, GM, Hyundai, Kia, and others are shipping with NACS ports.
- J1772 (SAE J1772): The original Level 1/Level 2 connector for non-Tesla EVs. If you have a Chevy Bolt, a pre-2025 Hyundai Ioniq 5, a pre-2025 Ford Mustang Mach-E, or similar, your car has a J1772 port.
- CCS1 (Combined Charging System): The DC fast charging connector for J1772 vehicles. Not relevant for campground charging since campground outlets only provide AC power.
Not sure what connector your car uses? Check the charging port. NACS is a smaller, oval-shaped port. J1772 is larger and round with a wider plug. Your owner's manual will also list it.
Wall-Side Adapters: Outlet to EVSE
Your portable EVSE plugs into the wall. Most come with a NEMA 14-50 plug (the 240V, 50-amp one) because that is the standard for home EV installations. To use other outlet types, you need wall-side adapters.
| Adapter | Converts | What It Does | Price Range | Important Notes |
|---|---|---|---|---|
| TT-30 to NEMA 14-50 | TT-30 outlet to 14-50 plug | Lets you plug your EVSE into a 30-amp RV outlet | $20 to $40 | NOT RECOMMENDED. Auto-reset risk can overload the circuit. See TT-30 section below. |
The TT-30 Adapter: Why We Do Not Recommend It
TT-30 to NEMA 14-50 adapters are sold everywhere online, marketed as the key to charging your EV at older campgrounds. We do not recommend them.
The first problem is wiring. There are two kinds of TT-30 to 14-50 adapters: ones made for RVs and ones made for EVs. They look similar but are wired differently. An RV adapter connects the neutral wire in a way that confuses an EVSE. If you buy the wrong one, your charger might not work, might throw error codes, or might work intermittently.
The second, more dangerous problem is the auto-reset risk. A TT-30 adapter presents your EVSE with a 14-50 receptacle. Your car thinks it is on a 240V, 50A circuit when it is actually on 120V, 30A. You can manually set your charge rate to 24 amps, but many EVs reset to their default (32A or higher) after any power interruption. Campground power interruptions are common. At 32 amps on a 30-amp circuit, you are overloading the wiring, the adapter, and the outlet. Cables melt. This is especially dangerous overnight while you are asleep.
If a park only has 30-amp service, use your Level 1 charger on the standard 120V household outlet instead. It is slower but safe. Or find a nearby public charger. See our outlet guide for the full breakdown.
We recommend skipping TT-30 adapters entirely. The auto-reset risk, combined with the RV-vs-EV wiring confusion, makes them the most dangerous piece of gear in the campground charging ecosystem. A Level 1 charger on a standard outlet is slower but will not melt anything.
Car-Side Adapters: EVSE to Vehicle
If your EVSE has one connector type and your car has another, you need a car-side adapter. This is mainly a concern during the NACS transition, where many public chargers and portable EVSEs still use J1772.
| Adapter | From | To | Who Needs It | Price Range |
|---|---|---|---|---|
| J1772 to NACS | J1772 EVSE plug | NACS vehicle port | Tesla owners using a J1772 EVSE, or NACS vehicles at J1772 public chargers | $50 to $120 |
| NACS to J1772 | NACS EVSE plug | J1772 vehicle port | J1772 vehicle owners using a Tesla Mobile Connector or NACS EVSE | $50 to $120 |
What to Pack by Vehicle Type
Here is the specific adapter kit for the most common EVs you will find at campgrounds.
| Vehicle | Port Type | Portable EVSE | Must-Have Adapters | Nice to Have |
|---|---|---|---|---|
| Tesla (any model) | NACS | Tesla Mobile Connector (NACS plug, 14-50 wall plug) | Level 1 (120V) charger as backup | NEMA 5-15 wall plug for Mobile Connector (trickle charging from standard outlets) |
| Rivian R1T/R1S (pre-2026) | J1772 | Rivian Portable Charger or aftermarket J1772 EVSE with 14-50 plug | Level 1 (120V) charger as backup | NACS to J1772 adapter for Tesla destination chargers |
| Rivian R2/R3 (2026+) | NACS | NACS EVSE with 14-50 plug | Level 1 (120V) charger as backup | J1772 to NACS adapter for older public chargers |
| Ford F-150 Lightning | J1772 / NACS (2025+) | Ford Mobile Charger or aftermarket EVSE | Level 1 (120V) charger as backup | NACS to J1772 or J1772 to NACS depending on model year |
| Chevy Bolt/Equinox EV | J1772 / NACS (2025+) | Included portable EVSE or aftermarket | Level 1 (120V) charger as backup | Connector adapter matching your model year |
| Hyundai Ioniq 5/6, Kia EV6/9 | J1772 / NACS (2025+) | Included portable EVSE or aftermarket | Level 1 (120V) charger as backup | Connector adapter matching your model year |
The one thing everyone should pack regardless of vehicle: your Level 1 (120V) charger as a backup. If a park only has 30-amp TT-30 outlets and no 50-amp service, the standard household outlet on the pedestal is your safest option. Slower, yes. But it will not overheat or melt anything.
The Complete Campground Charging Kit
Pack all of this in a bag that lives in your car. Campground charging is not a daily activity, and you will forget something if it is not pre-packed.
- Portable EVSE with a NEMA 14-50 plug (your car's included charger, or an aftermarket unit)
- Your Level 1 (120V) charger as a backup for parks without 50-amp service. We do not recommend TT-30 adapters due to the auto-reset overload risk.
- Connector adapter if your car and EVSE have different standards (J1772 to NACS or NACS to J1772)
- A short length of paracord or a carabiner to hang your EVSE off the pedestal so the plug does not rest on the ground
- Optional: a kill-a-watt meter or similar to verify outlet voltage before plugging in. Paranoid? Maybe. But a $20 meter can tell you if the campground wiring is sketchy before your $500 EVSE finds out the hard way.
A Note on DC Fast Charging Adapters
DC fast charging adapters (CCS to NACS, or NACS to CCS) are not relevant at campgrounds since RV park outlets only provide AC power. But they are relevant for the road trip to and from the campground.
If you have a CCS vehicle and want access to the Tesla Supercharger network, you will need a CCS to NACS adapter. If you have a Tesla or NACS vehicle, the Supercharger network is native to you. These adapters are separate from the campground kit discussed above, but worth having in the car for the trip.

Yes, you can charge an EV from an RV park power pedestal. But the details matter more than you think, and getting them wrong can trip a breaker, fry an adapter, or get you kicked out of the park.
How Fast Will My EV Charge at a Campground?
Campground charging is not DC fast charging, and that is fine. You are sleeping anyway. The real question is whether you will wake up with enough range to get where you are going, and the answer depends entirely on which outlet you plug into.
RV Park EV Charging Etiquette
RV parks were built for RVs. You are a guest in their world. The parks that welcome EV charging are doing you a favor, and the fastest way to lose that privilege is to act like the outlet belongs to you.
