Shaded rows are our picks. Assumed load: A 45-litre 12V compressor fridge pulling 45W when running, about 35% of the time in mild weather, plugged into the 12V socket.
Why the 12V socket beats the AC outlet
A 12V compressor fridge is built to run on DC, the kind of power a battery stores. Plug it into the power station’s car-style 12V socket and the power goes almost straight through. In our math, 90% of the battery reaches the fridge that way.
Use the fridge’s AC adapter in the household outlet and the power station has to turn DC into AC, then the adapter turns it back. It is like changing money into another currency and back: you pay a fee each way. Our math gives 85% for AC. The inverter (the part that makes AC) also uses some power just by being switched on. On the 12V socket you can leave it off.
Every model in the table has a 12V socket rated for 120W or more. The fridge needs about 60W to start and 45W to run, so all of them work.
What the fridge uses in a day
Our numbers assume a 45-litre fridge pulling 45W while its compressor runs. The compressor is the pump that moves heat out of the box, and in mild weather it runs about 35% of the time. That share is called the duty cycle.
Averaged out, that is about 16W, or about 380 watt-hours a day. A watt-hour is one watt used for one hour. After the 10% loss, a day costs about 420Wh of battery. Divide any battery’s capacity by 420 and you get days. Bigger fridges and dual-zone models draw more, and small ones draw less. Check the rated watts on yours and scale the numbers.
Heat is the big variable
The 35% figure is for mild weather. A fridge in a closed car in summer sun can run most of the time, which can cut these runtimes by half or more. Things that help:
- Park in shade and crack the windows. Keep the fridge itself out of direct sun, even inside the car.
- Leave space around the fridge’s vents.
- Chill the fridge and its contents on wall power before you leave.
- Open the lid less, and keep it full.
Setting it as a freezer also raises the draw a lot. Nights are easier, since cooler air lets the compressor rest more.
Set the low-voltage cutoff to low
Many 12V fridges have a battery protection setting, often marked high, medium and low. It is there to stop the fridge from draining a car’s starter battery. It works by switching the fridge off when the voltage at the plug dips.
On a power station you do not need that protection, and the high setting can shut the fridge off early while the station still has plenty left. Set it to low. The fridge’s manual shows how.
Use the fridge’s own 12V cord and push the plug in firmly. A loose plug in a car-style socket is a common reason a fridge cuts out.
Solar decides whether the trip has an end
Solar input is the most panel power a station can accept. Because the fridge needs only about 420Wh a day, even small inputs can keep up. A 100W input at full output covers the day in a little over four hours of strong sun. Panels rarely reach their rating, so a 200W panel is a safer match. The larger inputs in the table matter when you also run other things, or get only an hour or two of sun.
The picks in detail
Bluetti AC70
- 1.8 days
- 12V compressor fridge
- $359
- $0.47 per Wh
- 22.5 lb
- Weight
1.8 days on a charge covers Friday evening to Sunday afternoon in mild weather. It accepts up to 500W of solar, more than any other unit under 1,000Wh, so a panel can turn a weekend into a longer stay. At $0.47 per watt-hour it costs about half as much per day of cooling as the 300Wh units. In hot weather, expect noticeably less than 1.8 days and plan a recharge.
What fits
- 1.8 days per charge in mild weather
- 500W solar input
What does not
- 22.5 lb
- Falls short of a three-day weekend without a recharge

EcoFlow River 3
- 0.6 days
- 12V compressor fridge
- $239
- $0.98 per Wh
- 7.8 lb
- Weight
At 7.8 lb and $239, this is the lightest and cheapest unit in the table, and the one to grab for a beach day or a long drive. It runs the fridge for 14.0 hours, which is 0.6 days, so it will not get through a night and the next day. Its car socket is rated for 126W, well over the fridge's 60W startup need. EcoFlow's own US store was not listing it at our last check, so confirm you can still buy it.
What fits
- 7.8 lb
- $239
What does not
- 14.0 hours, not a full day
- $0.98 per watt-hour, about twice the AC70's rate
- Stock may be limited
EcoFlow's own US store was not listing this model when we checked, so stock may be limited. Confirm you can still buy it before you plan around it.
Bluetti Elite 100 V2
- 2.4 days
- 12V compressor fridge
- $489
- $0.48 per Wh
- 25 lb
- Weight
2.4 days per charge on its own, and a 1,000W solar input that matches the highest in the 1,000Wh class. The fridge takes about 420Wh of battery a day. With even a modest set of panels, this unit can put back more than that in a few hours of sun, so the trip has no fixed end date. At $489 it is the cheapest 1,000Wh unit in the table, at $0.48 per watt-hour.
What fits
- 2.4 days per charge
- 1,000W solar input
What does not
- 25 lb, 1.2 lb more than the Jackery Explorer 1000 v2
- Runs about 2.6 hours less than the Jackery

Anker Solix C2000 Gen 2
- 4.9 days
- 12V compressor fridge
- $899.99
- $0.44 per Wh
- 41.7 lb
- Weight
4.9 days per charge, with no panel and no driving. That suits a week at a shaded forest site where solar will not help much. Anker lists a 9W idle draw, which is low for this size and matters when the unit sits switched on for days. It takes up to 800W of solar when there is sun. At $899.99 it costs $0.44 per watt-hour, and at 41.7 lb it stays in the vehicle.
What fits
- 4.9 days per charge
- 9W idle draw listed by Anker
What does not
- 41.7 lb
- $899.99 is more battery than a weekend needs
Anker's list price is $1,499.99. Anker lists a 9W idle draw, which is low for this size.
Verdict
For weekend trips, buy the Bluetti AC70. It runs a 12V fridge for 1.8 days and takes enough solar to stretch that. For day trips, the EcoFlow River 3 is lighter and cheaper, if you can find it in stock, but will not last overnight and through the next day. If you camp with panels, the Bluetti Elite 100 V2 has the solar input to run without an end date. If you camp in shade for a week, the Anker Solix C2000 Gen 2 carries nearly five days with it.
How these numbers were worked out. Runtime = battery capacity × efficiency ÷ average watts. We use 85% efficiency for AC outlets and 90% for DC and USB ports, because some energy is lost as heat on the way out. A model is marked "can't run it" when the device needs more watts than the outlet gives, or a bigger startup surge than the unit is rated for. Your own device may draw more or less than our assumed load, so treat these as estimates. Prices were checked on 2026-10-04 and change often. Full method
