Capacity, per the listing

Roughly a long weekend for two. The listing also states a range down to 32 °F. Baskets and dividers eat some of it, so think in lunch boxes and milk cartons, not just in cans.

What it has going for it

What changes on your trips

21 qt, per the listing. A long weekend for two, or the drinks and lunches of a family day out, without an ice bag in sight. Our capacity guide turns that number into meals.

32 °F, stated. A fridge range for drinks and fresh food. A compressor holds that setting whatever the cabin heat, within the limits in the manual. Put a thermometer in anyway; our camping food guide says why.

App control. Check and change the temperature from the front seat or the tent, without unpacking the trunk to reach the panel.

Weekend trips or a week off-grid?

For weekend trips, 21 qt holds drinks and food until the next grocery stop. It pre-chills from the wall socket at home the night before. At 22.1 lb empty, per the listing, one person can lift it into the car.

On balance it shines on short trips; a week off-grid takes more power planning.

Great for you if…

You want a fridge that fits behind the seats
You like checking the temperature from the front seat
You want to pre-chill it at home before you leave

Skip it if…

You want a battery cut-off named: the listing we read names no battery protection
Star ratings come first for you: 4.2/5 is below the 4.5 average of our ranked picks

What Setpower promises

The seller states, word for word, in the Setpower RF20 21 Qt (50H Keep Cool) listing:

The SetPower 12V refrigerator provide ONE-ON-ONE friendly 3 years tech support on the compressor and 1 year maintenance on all other parts.
With Smartele refrigeration technology, this 12v fridge could achieve 15 min fast cooling from 77°F to 32°F and 45 min from 77°F to -4°F, keeping your food fresh.
You can switch between modes of the 12 volt refrigerator with the control panel or remotely via your phone app.

Their words and their figures, not our measurements.

Price and cost per quart of stated capacity

$169.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated quart of capacity costs about $8.09. That puts it in the pricier third of the 65 12V fridges we have a price for.

Only a rough yardstick: zones, battery, app and warranty count as much as the size.

A better fit for your trips?

Need room for longer trips? The ICECO VL60 Dual-Zone (9.3/10) states 60 L (63.4 qt).

Want fresh and frozen at once? The ICECO GO20 Dual-Zone (7.8/10) has two independent zones, per its listing.

Worried about the starter battery? The BougeRV CR22 23 Qt (9.2/10) names battery protection in its listing.

Our take

The verdict

We like the Setpower RF20 21 Qt (50H Keep Cool) for 21 qt of stated capacity and a range down to 32 °F. 237 buyers have had their say, which is plenty to go on. The catch with this Setpower 12V fridge: its 4.2/5 buyer average sits under the 4.5 of our ranked picks. We'd pick the Setpower if you want a fridge that fits behind the seats; otherwise, put it next to the Alpicool 28 Qt Car Fridge first.

Living with it

The night before

Plug it into the wall at home and let it pull down overnight, then load cold food, not warm. The seller quotes 45 minutes from 77 °F to 32 °F, so an hour gives you margin.

On the road

Plug it into a 12V or 24V socket and keep an eye on the temperature from your phone, and open the lid as little as you can stand on a hot day.

At camp

Keep it in the shade, leave the vents breathing and keep a thermometer inside. Our cleaning guide covers the wipe-down after the trip.

What buyers say

Buyers give it 4.2/5, a solid record, below our ranked picks' 4.5 average. 237 reviews is a fair sample, enough for the average to mean something.

The numbers

Buyer rating: 4.2/5
Reviews: 237
Ranked picks' average: 4.5/5

The one thing we'd check first

One thing to settle before the Setpower RF20 21 Qt (50H Keep Cool) ships: check the socket, because a 21 qt fridge on a car socket needs that socket to stay live with the ignition off.

Before you buy

The space

Measure the spot with the luggage in and the lid fully open, and leave room around the vents. Our fridge fit planner runs the numbers.

The socket

Switch the ignition off, plug a phone charger into the socket and see whether it still charges. Then decide on a battery cut-off. Our power connections guide has the checklist.

The food

A display shows a setting, not the temperature of every container, so keep a cheap fridge thermometer inside. Our camping food guide explains why.

The paperwork

The listing states a 3-year warranty. Look up who handles the warranty, and keep the receipt with the manual.
