Charging an EV at an RV park

An RV site has the outlet your apartment does not: a NEMA 14-50, outdoors, on its own circuit, next to a parking space. For a renter with no reachable 240V at home, a campground is one of the few places that combination exists and is legitimately rentable by the night.

This is a fallback rather than a plan. It costs the price of a site, it takes a trip, and it depends entirely on the park saying yes. But for somebody who occasionally needs a full battery and cannot get one at home, it is a real option — and it uses equipment this site already recommends.

RV pedestals typically carry more than one receptacle, and they are not interchangeable. The one that matters is the 50 amp: a NEMA 14-50, the same four-prong receptacle covered in detail on the 14-50 page. If the site you are offered has one, a plug-in 40 amp charger works exactly as it would at home.

Park policies on EV charging vary and some prohibit it outright, usually because a car drawing 40 amps all night is not what the site's electrical budget was planned around. Call ahead, say plainly that you want to charge an electric car from the 50 amp receptacle, and ask whether that is permitted and what a night costs.

Two reasons to do this rather than turn up and plug in. The first is that being told no on arrival wastes the trip. The second is that charging without asking is exactly the behavior that gets a park to ban it for everyone, and the same courtesy logic applies here as in a shared laundry room.

The kit is the same one this site recommends for a dryer outlet or a range outlet at home, which is the point — nothing here is RV-specific. A plug-in Level 2 charger with a NEMA 14-50 plug covers the 50 amp pedestal. An adjustable unit covers a site that turns out to have something smaller. A Level 1 unit covers the case where all you can reach is a household socket by the bathhouse.

Lectron Portable Level 2 J1772 Charger (40A, NEMA 14-50)

The plainest answer to a NEMA 14-50 outlet you can reach: 40 amps, a plug on the end, and nothing screwed to a wall you do not own.

Published specifications for the Lectron Portable Level 2 J1772 Charger (40A, NEMA 14-50), each linked to its source

Input	240V, 40A maximumsource
Output power	Up to 9.6 kWsource
Cable length	16 ftsource
Plug / connector	NEMA 14-50 plug, J1772 connectorsource
Certification	UL 2594 / UL 2231 certifiedsource
Manufacturer charge-rate claim	Roughly 30 miles of range per hour of chargingsource

What those numbers mean

9.6 kW is the ceiling this unit can deliver, not what your car will take. A vehicle with a 7.2 kW onboard charger draws 7.2 kW from it and no more, and that is a car limitation no charger fixes.

The 16 ft cable is the number to check before anything else. Measure from the outlet to where your charge port sits when the car is parked as it will actually be parked, not as you would like to park it. Sixteen feet disappears faster than people expect once it has to route around a wall.

A 40 amp unit needs a 50 amp circuit behind the outlet to run at 40 amps continuously. If the outlet is on a smaller breaker, the answer is a lower-amperage charger, not this one turned down.

What it does well

• Plugs in and unplugs — it leaves with you at the end of the lease
• UL 2594 and UL 2231 certified, the two standards that matter for EVSE
• 40 amps covers the fastest charging any renter-reachable outlet realistically supports

What it does not

• 16 ft of cable is short for a parking space that is not directly beside the outlet
• No amperage adjustment, so it is the wrong unit for a 30 amp circuit

Skip this one if: Your only 240V outlet is a 30 amp dryer receptacle. This unit expects a 50 amp circuit behind a NEMA 14-50, and derating it is not an option it offers.

#2 · Not knowing your outlet yet

Grizzl-E Mini Connect Portable Charger

Adjustable from 7 to 40 amps and shipped with four plug adapters, which is the closest thing to a unit that fits whatever outlet you turn out to have.

Published specifications for the Grizzl-E Mini Connect Portable Charger, each linked to its source

Adjustable current	7A to 40A (9.6 kW maximum)source
Voltage	Automatically detects 120V (Level 1) or 240V (Level 2)source
Cable length	25 ft (7.6 m)source
Plug and adapters	NEMA 14-50 plug plus four included electrical adapterssource
Connector	J1772 or Tesla (NACS) versionssource
Enclosure	UL Type 4 / IP67 ratedsource
Certification	UL tested and certified, Energy Star certifiedsource

What those numbers mean

The adjustable current is the feature that matters to a renter, and it is not a convenience. A 30 amp dryer circuit legally supports 24 amps of continuous EV load; a unit that can be set to 24 amps can use that circuit, and a fixed 40 amp unit cannot.

25 ft of cable is nine feet more than the common 16 ft, and nine feet is frequently the difference between reaching the car and not.

IP67 and a UL Type 4 enclosure describe the unit's own weather tolerance. They say nothing about the outlet it plugs into, which is usually the part that is not weather-rated.

What it does well

• 7-40A adjustment means one unit fits a 15, 20, 30 or 50 amp circuit
• 25 ft cable is among the longest on a portable unit
• Four plug adapters included, so an outlet change does not mean a new charger
• Available with either a J1772 or a NACS connector

What it does not

• Costs meaningfully more than a fixed-amperage unit that does one job
• The bundled adapters make it easy to plug into a circuit you have not actually checked

Skip this one if: You know exactly which outlet you have, it is not changing, and you would rather put the money into a longer cable than into adjustability you will set once and never touch.

#3 · An ordinary wall socket

Lectron Portable Level 1 J1772 Charger (15A, NEMA 5-15)

The unglamorous answer that covers most commutes: an ordinary 120V socket, overnight, and no conversation with anybody about electrical work.

Published specifications for the Lectron Portable Level 1 J1772 Charger (15A, NEMA 5-15), each linked to its source

Input	120V, 15A maximumsource
Output power	1.8 kWsource
Cable length	16 ftsource
Plug / connector	NEMA 5-15 plug, J1772 connectorsource
Certification	UL 2594 / UL 2231 certifiedsource
Manufacturer charge-rate claim	45+ miles of range overnightsource

What those numbers mean

1.8 kW sounds trivial next to 9.6 kW, and for a road trip it is. For a commute it usually is not: the average US driver covers well under 45 miles a day, and this replaces that overnight while the car sits anyway.

The honest ceiling is the circuit behind the socket, not the cable. This unit draws 15 amps for hours, which a 20 amp circuit supports continuously and a 15 amp circuit does not — so check the breaker before the first overnight session, and on a 15 amp circuit choose a 12 amp unit instead.

This is the only category of EV charging that is genuinely invisible to a landlord. It draws less than a hair dryer and plugs into a receptacle that already exists.

What it does well

• Works with a socket that already exists, everywhere, with no permission needed
• UL 2594 and UL 2231 certified rather than a generic cordset
• Cheapest possible entry into home charging, by a wide margin

What it does not

• 1.8 kW will not recover a long driving day overnight
• 16 ft cable, and the nearest 120V socket is often not the nearest thing to the car
• Its 15 amp draw needs a 20 amp circuit behind the socket; an ordinary 15 amp circuit supports 12 amps continuously

Skip this one if: You regularly drive more than about 45 miles a day. Level 1 will fall a little further behind every night and you will spend the difference at public chargers.

Run that comparison honestly before making a habit of it. A campground site fee is not cheap electricity; it is a night's rent that happens to include an outlet. It wins against DC fast charging on price surprisingly often, and loses badly against a home outlet you could have negotiated for — which is why the landlord request letter is still the higher-value move.

• Look at the receptacle before you plug in. Scorching, a loose fit or a cracked face means find another site. Pedestals live outdoors and take abuse.
• Set the current deliberately if your charger allows it. The pedestal's breaker is the limit, and running below it is the cheapest insurance available.
• Use a drip loop and keep the charger off the ground. Charging outdoors safely covers the rest.
• Check the plug after an hour. Warm is normal, hot is not — a hot outlet or melted plug is the page to read if it is.
• Do not leave the cable across a road or a footpath. It is a trip hazard and it is the fastest way to have the park change its mind.

A short, specific call saves a wasted drive, and being straightforward about what you want makes a yes considerably more likely than turning up and improvising. Five questions cover it.

1. 1Do you allow electric cars to charge from the site pedestal? Ask first and ask plainly. Some parks say yes without hesitation, some have a flat policy against it, and a few charge a supplement.
2. 2Does the site have a 50 amp hookup? This is the NEMA 14-50. Without it you are looking at Level 1 speeds and the trip may not be worth making.
3. 3What does a night cost, and is there a day-use rate? Some parks will sell a few hours rather than a full night, which changes the arithmetic completely.
4. 4Can I park a car rather than an RV on the site? Worth asking explicitly — a few parks are set up only for rigs and will say so.
5. 5Is the pedestal metered? Where it is, you may be charged for what you use on top of the site fee, which is fairer for everybody and worth knowing in advance.

Being upfront also protects the option for the next person. Parks that discover cars charging unannounced tend to write a rule; parks that are asked tend to quote a price.

An RV site is one of four fallbacks available to somebody with no home charging, and it is worth knowing where it sits before making a habit of it.

The point of the table is that a campground night is rarely the cheapest option and almost never the most convenient — it is the one that reliably produces a full battery on your own schedule when nothing else will. Home vs public charging prices the second row properly, which is the comparison that usually decides it.

It happens, and it is worth having a second option rather than arguing. Some parks have been burned by somebody drawing 40 amps all night on a site rented at a tent rate; others simply have not thought about it and default to no.

Two things sometimes change the answer. Offering to pay the 50 amp site rate rather than the cheapest rate addresses the actual objection, which is almost always about electricity cost rather than about cars. And asking whether they meter the pedestal gives them a way to say yes that protects them — if you pay for what you use, their risk disappears.

If the answer is still no, take it gracefully and look at the other rows in the table above. A relative's dryer outlet or a workplace socket will usually beat a campground on both cost and convenience anyway, and the pillar page works through the options in order of how much they cost you.

Two practical constraints that catch people out. Parks fill up in summer and around holidays, so the availability of a 50 amp site is worst exactly when travel demand is highest — book rather than assume. And a pedestal outdoors in winter is a cold, wet receptacle: the charger's own weather rating matters less than whether the outlet has an intact while-in-use cover, which is the part nobody maintains.

If the cover is missing or broken, that is a reason to ask for a different site rather than to improvise. Charging outdoors safely covers what weather does and does not affect, and the drip loop that costs nothing.

For a renter with no home charging at all, an occasional campground night is a way to get a full battery without paying fast-charging rates for every kilowatt-hour. It also works as a road-trip tactic in areas with thin DC coverage, where a site with a 14-50 may be easier to find than a working fast charger.

It is not a substitute for solving the problem at home. If there is any 240V outlet within reach of where you park — a dryer circuit, a range outlet, a laundry room — that is cheaper, closer and repeatable. Start at the pillar if you have not worked through those options yet.

Individual parks. Policies, pricing and pedestal condition vary site by site and change without notice, so everything here is written as questions to ask rather than answers we can give for a place we have not visited. The charger specifications come from each manufacturer's published documentation, cited on every pick. The method sets out the limits.
