Camping With an EV or Hybrid in Australia 2026: Can You Run a 12V Fridge?

Quick answer by vehicle type

Why your mate’s dual-battery setup does not transfer

Walk through any bush camp and you will find the same system in half the 4WDs: a second battery under the bonnet or in the canopy, charged off the alternator through a DC-DC charger, feeding an Anderson plug that runs the fridge. It works, it is well understood, and every 4WD shop in the country will fit one.

None of it applies to an EV.

There is no alternator. In an electric car the 12V battery exists to wake the car up and run its computers, lights and locks. It gets topped up by a DC-DC converter from the high-voltage drive battery, but only when the car is awake. It is small, it is not designed for house loads, and there is no charging circuit for you to tap the way you would tap an alternator.

The failure mode is worse than a flat battery in a petrol car, too. A dead 12V battery in an EV means the car cannot power up its own contactors, so it cannot connect the big battery to anything. You have a full drive battery and a car that will not turn on. Jumper leads and a mate’s Hilux do not fix this the way they fix a flat starter battery.

Dad’s call: do not let anyone talk you into wiring an aux battery into an EV’s 12V system. If someone offers, ask them how many they have done. The answer will tell you what you need to know.

Conventional hybrids have the same no-alternator problem, and the 12V battery is often even smaller.

V2L is the bit that changes everything

Vehicle-to-load does the opposite of charging. Instead of pushing power into the car, the car pushes power out through a normal Australian powerpoint, either from a socket inside the cabin or through an adapter that plugs into the charge port.

The output is the headline number. Most V2L-equipped EVs sold here deliver up to 3.6kW. MG’s adapter and some BYD setups are rated at 2.2kW. Either figure comfortably runs a fridge, lights, a kettle and a laptop.

Which cars have it in Australia

Two things worth knowing before you buy an adapter off eBay. First, V2L has to be built into the car. If the vehicle does not support it, no adapter unlocks it. Second, adapters run roughly $70 to $200 and some models do not include one in the box, so check before you assume you have it.

Checking your own car: Hyundai Australia lists the Ioniq 5’s V2L output at 250V / 15A, or 3.6kW, through both the interior outlet and the charge-port adapter. Kia Australia confirms the EV6 runs a standard Australian outlet inside the car with no adapter needed, plus the exterior adapter for bigger loads. For a cross-brand comparison, EV Roadside’s V2L guide tracks which models have it and at what output.

The maths: what a fridge actually costs you

This is the part that surprises people.

A 40 to 50L compressor fridge in Australian conditions averages somewhere around 30 to 60W across a full day, because the compressor cycles rather than running flat out. Call it 1kWh over 24 hours for an easy number.

Now put that against the car:

Three nights of cold beer costs you less range than the drive to the shops and back. Compare that to a 1,000Wh power station, which is fully flat after one day of fridge duty and nothing else.

Your EV is not competing with a power station. It is roughly seventy of them.

The setup I would actually run

Here is where most people get it slightly wrong. The instinct is to plug the fridge straight into the V2L socket and leave it running overnight. It works, but it wastes power and keeps the car awake.

The inverter that makes V2L possible has its own idle draw, usually somewhere in the 50 to 100W range just to be switched on. Run that for 24 hours and the inverter costs you more than the fridge does. You have effectively tripled your consumption to run one appliance.

Better approach: use the car as the generator, not the extension cord.

1. Run the fridge off a power station’s 12V DC output. No inversion losses, no idle penalty. This is the most efficient way to run a 12V appliance, full stop.
2. Top the power station up once a day from V2L. Thirty minutes at 2kW puts about 1kWh back in, which is your fridge covered. Do it while you are cooking dinner and the car is awake anyway.
3. Set a discharge floor. Most V2L cars let you set a minimum state of charge, below which V2L shuts off. Set it around 30% so you physically cannot strand yourself.
4. Add a solar blanket if you are staying put. On a clear Australian day a 200W blanket largely covers the fridge on its own, and the car becomes the backup rather than the daily source.

This gets you the best of both. The power station does the quiet, efficient overnight work. The car carries the reserve.

Conventional hybrids are the awkward middle

A RAV4 Hybrid, Kluger Hybrid or Camry Hybrid gets you neither option. There is no alternator to run a dual-battery system from, and there is no V2L socket to plug into. The traction battery is small and the car will not let you touch it.

So if you are camping out of a conventional hybrid, your setup is identical to what you would run out of a petrol hatchback: a power station and a solar blanket. Size it as though the car is not there, because as far as your fridge is concerned, it is not.

PHEV utes are the other end of the scale. The Ford Ranger PHEV and BYD Shark 6 carry serious onboard power output plus a petrol tank for when the pack runs down, which makes them the most capable camping power setups on sale right now. If you are shopping for a tow vehicle and a campsite generator at the same time, that is the category to look at.

Five things to watch

1. Inverter idle draw. Covered above. The single most common mistake.
2. Auto shutdown. Some cars power down V2L after a set period of inactivity or low draw. A fridge that cycles off can be read as “nothing plugged in.”
3. Charging access. Running the fridge is trivial. Getting the car home from a remote camp is the real planning problem. Check charger coverage on your route before the trip, not during it.
4. Towing range. A camper trailer or van can cut EV range close to half. That is a route-planning issue, not a fridge issue, but it hits the same trip.
5. Rain and extension leads. A charge-port V2L adapter sits outside the car. Keep the connection dry and off the ground, and use an outdoor-rated lead.

Honest disclosure

I do not own an EV. This came out of a weekend at Glenworth Valley where the carpark had more EVs and hybrids in it than I expected, which made me go and work out how the power side actually functions.

Everything above is based on published manufacturer V2L specifications, real fridge consumption figures, and the physics of what an inverter costs you to run. I have not personally run a three-night V2L setup. When I do, this post gets updated with what the numbers actually looked like rather than what they should look like.

If you have run a fridge off V2L in Australian conditions, tell me what you found. That is the sort of thing that makes this post worth reading in twelve months.
