Best power station for van life and car camping with a 12V fridge

The fridge decides this. It’s the one thing in a van or a car that runs all day and all night, so the question is how many days of fridge you want in the box before you have to put power back. That’s a very different number for a night at a trailhead than for a long weekend parked in the shade with a dual-zone freezer, which is why we’ve picked per trip.

How we picked

From the stations in our data, we ranked on:

1. Days of fridge per charge. Calculated runtime on the 12V car port, from Dometic’s daily energy figures at its hot-day test conditions. Divide the hours by 24 for days.
2. Whether the 12V port carries the fridge. We check each fridge’s rated input current against the car port. All the stations we have share one rating, 10 A, so a bigger station doesn’t get you a bigger port. It rules out one fridge, not any station.
3. Solar input, for when you’re parked for days and topping up from panels.

Every one of them is LiFePO4. Weight, dimensions, vehicle charging rates and expansion batteries aren’t in our data, and in a van they can all matter, so look them up in the manuals before you buy. These hours are calculated, not measured, and a van sitting in full sun will likely use more than Dometic’s figure.

The single-zone fridge, station by station

This is the Dometic CFX3 45, a mid-size single-zone fridge, on the stations we pick from below:

Use the 12V DC rows. They beat AC on every station because the car port skips the inverter. If you want the same numbers for other CFX3 sizes, they’re in the 12V fridge runtime table.

The picks

Overnights and day trips, recharging daily: EcoFlow RIVER 3 Plus

If you drive every day and the station gets charged most days, a small one can work with a small fridge. The Dometic CFX3 25 on the RIVER 3 Plus works out to 23.5 hours, which is about a day. Of the three small stations we have, it has the most capacity and the most solar input (220 W). The Bluetti EB3A is close.

A day is all it gets you, though. Miss one charge and the station runs flat about a day in. We don’t carry vehicle charging rates, so check how fast your station refills from the car before you rely on the drive to do it.

A weekend with no charging: Bluetti AC180

For two or three nights off the grid with a single-zone fridge, you want the kilowatt-hour class. From the table above, the AC180 runs the CFX3 45 for 84.0 hours, which is about three and a half days, and it’s the biggest of the kilowatt-hour stations. The EcoFlow DELTA 2 is a little behind and fine if your trips are shorter.

Parked for days with roof or folding solar: Bluetti Elite 100 V2

It holds the same as the DELTA 2, but its solar input is rated at 1,000 W, double the DELTA 2’s 500 W. That’s what you want if you’ll sit somewhere sunny and let panels carry the fridge.

You only see that difference with a decent amount of panel. One folding panel from our data (220 W or less) fits under every kilowatt-hour station’s limit, so with a single panel the panel is the bottleneck, not the station. Put your roof array through the solar recharge calculator and see whether you’d ever reach the Elite’s higher limit.

One more caveat. Bluetti’s manual gives no surge rating for the Elite 100 V2, so our checks use its continuous rating for startup loads. That doesn’t matter for the fridge on the 12V port. It might if you plan to start something with a motor off the AC outlet.

Dual-zone fridge with the freezer on, or a fridge plus a CPAP: Bluetti AC200PL

Set the small zone of a dual-zone fridge to freeze and it uses about twice as much. That’s where the kilowatt-hour stations stop being enough for a weekend:

The AC200PL has more battery than the Bluetti Elite 200 V2, and more solar input too (1,200 W against 1,000 W). With the freezer on, it runs the Dometic CFX3 75DZ for 57.0 hours. That’s a bit over two days, not a week.

A fridge and a CPAP on one battery works the same way. A ResMed AirSense 11 on its own gets 37.0 hours from the AC200PL on its DC adapter, and every night of CPAP comes out of the fridge’s days. Our van and RV sizing guide shows how to add loads together.

We passed on the Jackery Explorer 2000 v2 here because we haven’t confirmed its solar input limit from the manual, and for a van that sits for days, solar is how you put power back.

A week or more without charging: EcoFlow DELTA Pro

The DELTA Pro is the biggest station in our data. On the single-zone CFX3 45 it’s 262.0 hours, more than ten days, and it also has the highest solar input we have (1,600 W). For weekend car camping that’s far more than you need. It earns its place in a van where you stay put a long time, or where you also run big AC appliances. We go through it against the Elite 200 V2 in DELTA Pro vs Elite 200 V2 for a van or RV.

The fridge none of these can run from the car port

Dometic rates the Dometic CFX3 95DZ above the car port limit on every station we have. Our check says it runs, but only from the AC outlet:

We go by Dometic’s rated current, and on that the car port is out. If you want the 95DZ, size the station on its AC rows and expect fewer hours than the same station gives a smaller fridge. CFX3 75DZ vs CFX3 95DZ has the details.

What we’d skip

The EcoFlow RIVER 3. Even the smallest CFX3 gets 20.0 hours out of it, short of a day, and a single folding panel gives it more than its solar input (110 W) can take.
