What it's made for: the car, the boat and the campsite.
The two portable 12v fridges closest to it on our rating, with a dated price.
Roughly a long weekend for two. The listing also states a range down to -4 °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
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.
-4 °F to 68 °F, stated. Cold enough to run it as a freezer, so ice packs and frozen meals are on the menu. 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.
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.
On balance it shines on short trips; a week off-grid takes more power planning.

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

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 Setpower RF20 21 Qt earns its place with 21 qt of stated capacity and a range down to -4 °F. 463 buyers back that up with 4.5/5, about as reassuring as a review record gets. The catch with this Setpower 12V fridge: no battery protection in the listing, while most picks here name one. We'd pick it if you want a fridge that fits behind the seats; otherwise, put it next to the Alpicool 43 Qt Dual-Zone first.
Plug it into the wall at home and let it pull down overnight, then load cold food, not warm. The seller quotes 15 minutes from 68 °F to 32 °F, so an hour gives you margin.
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.
Keep it in the shade, leave the vents breathing and keep a thermometer inside. Our cleaning guide covers the wipe-down after the trip.
Buyers give it 4.5/5, a strong record, right on our ranked picks' 4.5 average. And with 463 reviews behind it, that number is hard to argue with.
Before you order the Setpower RF20 21 Qt: check the socket, because a 21 qt fridge on a car socket needs that socket to stay live with the ignition off.
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.
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.
A display shows a setting, not the temperature of every container, so keep a cheap fridge thermometer inside. Our camping food guide explains why.
Look up who handles the warranty, and keep the receipt with the manual.

We rate it 7.1/10 (good). It is based on 463 buyer reviews averaging 4.5/5 and the specifications stated in the listing.
Its listing states 21 qt of capacity. Those are the seller's figures, not our measurements: how fast it cools, how much it draws and how loud it hums depend on the heat outside, the load and the setting.
Measure the space with the lid fully open and leave room around the vents. Then check the outside dimensions in the manual, the 12/24V DC and AC cords in the box, the battery protection settings and whether your car's socket stays live with the ignition off. Our fridge fit planner runs the space check for you.
