If ice-a-plenty and fast cooling are your primary goals, EcoFlow’s Glacier is a good bet. Once powered up, its powerful compressor can freeze the compartments in 15 minutes and churn out a tray of cubes about every 12 minutes (the first batch takes a bit longer).
It’s also a dual-zone unit, which means you can stash plenty of those cubes in the freezer while maintaining a refrigerated section for drinks and food. That makes this cooler ideal for soccer games, family reunions and company parties in the park. Like BougeRV’s Rocky, the divider between the compartments is removable, which is handy when you need the extra length to stash a salmon or a baking dish.

The Glacier can be powered through an AC outlet, a 12V car outlet or an optional 298 Wh battery, which neatly stows inside the cooler’s housing. EcoFlow claims its battery will power the cooler for 40 hours, but don’t bet on that under real-world conditions, especially if you open it to retrieve items, if it’s warm outside or if you intend on making ice. During our tests, in the shade, with ambient air temperatures in the 80s, and grabbing an occasional beverage from it, it lasted more like nine hours — so if you need to use it for any length of time off-grid, plan on buying extra batteries or a larger portable power station.
On the bright side, the battery also accepts 240 watts of solar input, which is the highest of any built-in battery in this lineup. It can also be charged via USB-C and charge other electronics.
As for the ice maker, it draws water from a 1.4-liter tank, which can make about five batches of ice But, one of our biggest complaints about this model is that the ice maker won’t run on 12V power, so you either need to be plugged into AC power or buy the battery.
Personally, we don’t long for ice makers in a portable cooler. They take up storage capacity and add weight. With a dual-zone cooler like this, we prefer to make ice the old-fashioned way, with a couple of trays. But if you’re having friends over for cocktails, the novelty is pretty nifty, plus the quick freezing speed of the ice maker will keep the party going more reliably.
On the downside, this cooler is expensive if you don’t find it on sale. Plus, you still have to buy the battery, wheels and tow handle separately.

We adore this dual-zone Dometic, partly because it was our first electric cooler but also because after three years of heavy use and flat-out abuse—including exposure to dust storms, extreme heat and thousands of rocky off-road and washboard miles—it’s still going strong. It even saved us hundreds of dollars in food when our house fridge broke down.

With a 79-quart capacity, it’s among the largest electric coolers on the market, comparable to the Newair model in this write-up. Dometic is known for making particularly good yet expensive RV appliances, and this model is no exception. It’s more than twice the price of the Newair (but still the same price as the EcoFlow Glacier), which is the main reason why we awarded the Newair the best dual-zone electric cooler instead of this one.
The Dometic cooler is also a lunker. Empty, it weighs 61 pounds. Full, it takes two people to carry it (I finally wised up and now take the baskets of food out first before lugging it long distances, duh). It doesn’t come with wheels or a pull handle, either, but you can buy a slide and tie-down kit for it, which is nice if you’re planning on installing it in your van or camper.

But this cooler does hold a lot of food, and it’s very sturdy. Dometic doesn’t list any internal component specs, but after the thousands of hours we’ve run it, it’s safe to say they are of high quality. Cosmetically, however, we have managed to chip the decorative plastic on the outside, but that’s been easily fixable with a bit of J-B Weld. Oh, and the compressor is also very quiet.
Despite its size, it’s great at power conservation, drawing only 60 watts when the compressor is running (25% less power draw than the Newair). Dometic also sells 200 Wh and 960 Wh batteries, which attach to the outside and have solar ports. We never opted for that option, though, since we have a portable power station to run it from when we’re off-grid. Dometic makes a range of other electric coolers, too, all the way up to a 104-quart beast.

Pros:
-
Uses Ryobi tool batteries
-
Can be a freezer or fridge
-
Good warranty
-
Lightweight
Cons:
-
Single zone
-
No solar option
If you already use Ryobi tools, then adding this electric cooler to your job site or tailgating kit is an obvious choice. It can run off of one or two Ryobi 1 batteries, plus it comes with cords for an AC wall outlet or a car 12V electric socket.
For an electric cooler, it is lightweight enough to solo lift in and out of the truck. It’s also refreshingly straightforward: there’s just one compartment, which can be set as a fridge or freezer. It holds up to 40 12-ounce cans and comes with an impressive 3-year warranty. There are also tie-down loops, an integrated bottle opener and a USB-A port for charging your phone.

The LCD screen is easy to use and displays both the temperature and battery level. It’s also easy to clean, thanks to the single compartment with a drain. We accidentally put that to the test when we used it to temporarily store a bag of fresh-roasted green chiles, which had a leak in it. The ensuing layer of gooey, dark liquid wiped right up and didn’t leave a trace.
The biggest downside to the Ryobi One+ cooler is that it doesn’t come with any batteries, and those are pretty pricey. So if you don’t already use Ryobi battery-powered products, there are far better deals out there on other electric cooler brands. For its size, this cooler is also on the expensive end, even if you’re already in the Ryobi family. Plus, the battery configuration is a little clunky, with the battery compartment taking up more room than it needs to. On the upside, the color scheme means you’ll never lose it, even in the dark.
This cooler is a little small for most camping needs, but it is perfect for keeping a stock of refreshingly cool drinks and unspoiled burritos and sandwiches. Because it’s so lightweight and portable, we’ve been using it both on the job site, where we’re building a workshop, on day trips to go leaf peeping, and on runs to the big city to pick up materials and supplies. It would also be a great choice for long- and short-haul truck drivers.
Specs
- 24-quart capacity

What to Look for When Buying an Electric Cooler
Cooling Technology
There are two main categories of cooling technology being used in electric coolers: compressor and thermoelectric. Thermoelectrics generally use less power, are lighter, and don’t contain potentially environmentally harmful refrigerants. On the downside, they don’t get nearly as cold, especially when it’s hot outside. If a cooler doesn’t advertise zero or sub-zero cooling, it’s probably thermoelectric.
If you live in a cool place or just need to keep some veggies from spoiling, a thermoelectric might do the trick.
"If your trip is long or you work under hot conditions, the compressor model will provide far more dependable performance."

Compressor Technology
Most people opt for a cooler with a compressor, but not all compressors are equal. Recent compressor technology developments, such as variable-speed and inverter compressors, are more energy-efficient compared to traditional or single-speed compressors, says Mosaferi. To ensure that you get the latest compressor technology, look for the term “inverter technology” in product descriptions, he says. (Note: We have yet to see an electric cooler brand touting what compressor tech they’re using.)
Size and Weight
KARUNA EBERL FOR FAMILY HANDYMAN
With an electric cooler, you’ll save internal space that would be filled with ice. But, because of the compressor size, electric coolers are larger overall than regular coolers. So when deciding what size to get, consider both the inner capacity and the outer dimensions, as well as the weight — because these guys can get pretty hefty.
Power Options
Most models can be powered through a wall or generator outlet (AC), 12V car outlet (DC) or built-in/detachable lithium batteries. A few come with the batteries, but most are an additional purchase. Many have built-in solar inputs as well. Otherwise, if you want to power your cooler via the sun, you could bring along a portable power station with solar panels.
Energy Use (Watt-hours)
The energy efficiency of electric coolers depends on their compressor technology and the quality of insulation. If you’re just plugging your electric cooler into the wall, then how many watts it uses isn’t much of a factor. But if you’re running it off of a battery, a battery being recharged by solar, or your car/RV battery, then more efficient models make life a lot easier.
When calculating how many watt-hours it will take to run a portable cooler, keep in mind that the compressor won’t be running once the cooler is down to temperature. Of course, the more you open the lid or the hotter it is outside, the more the compressor will run and the more watt-hours it will consume.
Cooling Zones
Some larger-capacity electric coolers offer dual-zone cooling, which means one side can be a refrigerator and one a freezer. Often with these, you can also set both sides as a fridge or both as a freezer. The better ones have independent lids for each side. Note: A few models have two sides but can’t be set at independent temperatures, so check that before you buy if that’s an important feature for your needs.
Other Features
KARUNA EBERL FOR FAMILY HANDYMAN
Other features that can add to your portable cooler bliss include:
- Adjustable temperature controls,
- Durable construction for outdoor use,
- Wheels and a pull handle, especially for larger models,
- USB charging outlets for phones and other devices, and
- Bluetooth or Wi-Fi app controls.
Note: None of the models we tested have warming options, but some thermoelectric models, like the 4Patriots Freedom Fridge, can actually heat compartments up to 149 degrees F.
Why You Should Trust Us
My partner and I have been testing and writing about outdoor, camping and workshop products for nearly 30 years. For the last three years, we’ve been putting electric coolers and portable power stations through the wringer, from high-elevation mountains to vast deserts and even tropical islands. We’ve been using them for car and van camping, including weeks-long remote overland expeditions, where solar was the only power source. Back at home, we’ve also been testing electric coolers on our job site and building a new workshop.
Other Electric Coolers We Tested
This electric cooler is affordable and easy to carry, being less than 19 pounds. It also draws very little power since it uses thermoelectric technology, compared to the compressors used in the rest of the coolers we tested. If you live in a cool climate and don’t need freezer temperatures, this could be a realistic choice. Also, if you start with frozen food and don’t open the lid, this cooler could keep it from spoiling for a couple of days, so long as it’s not parked in the sun. But otherwise, the technology can only effectively make it 38 degrees cooler than the ambient air temperatures, which means it’s really only practical if it’s less than 60 degrees outside.
Part cooler, part air conditioner, the IcyBreeze is a novel concept that we thought might be a bit kitschy, but which actually works really well. The only reason we’re putting it down in this section instead of featuring it up top is an annoying technicality — it’s not actually an electric cooler. Instead, it’s a high-quality rotomolded traditional cooler with a three-speed fan (similar in concept to an evaporative cooler). Put water or ice inside, and it’ll blow cool air or even mist your way. The air that comes out is 35 degrees F or so below ambient air temperatures, and the cooling lasts for two or three hours. The IcyBreeze is perfect for cooling off at the pool, a soccer match or anywhere else where you’re feeling overheated. We particularly like it for dogs, to give them a break in cars with poorly functioning AC or at the end of a hot hike. It holds 38 quarts, and there’s an optional battery. It also has tie-down points, all-terrain wheels and a USB charging port.
How We Found the Best Electric Coolers
After analyzing 15 electric cooler manufacturers, we settled on 10 we wanted to try. We opted for models with various sizes and features to ensure we included ones for an array of uses, from job sites and picnics to extended car and RV camping.
From there, we evaluated each on its power efficiency (watt-hour use), size and weight, price, power options, cooling zones, pull handles and wheels and other user interfaces. We also tested how well they performed in various scenarios over the course of the summer, including:
- How long it took to freeze trays of ice
- How fast they were able to get down to temperature
- How well they held their temperature in the heat
- How easy it was to clean up spills
- How practical they were for packing food and
- How easy they were to transport.
After adding all of that up, we picked our favorites for various uses, whether that meant going to the beach, living on the road or storing drinks for the crew.
FAQ
How long do electric coolers stay cold?
It depends on the power source you’re using. If it’s plugged into a wall outlet, it will stay cold indefinitely. If it’s running off of a battery, it depends on how many watts the battery holds versus how many watts the cooler is drawing. Most coolers that come with batteries advertise between 4 and 40 hours of runtime, though that will be largely affected by the outside air temperature and how often you open the cooler (which will make the compressor have to run more often). If the electricity gets cut off, as long as you don’t open the lid, most electric coolers will still keep your food from spoiling for several hours or even days, similar to a regular cooler.
Can you leave an electric cooler plugged in all the time?
Yes. Electric coolers can stay plugged in indefinitely, though as with any appliance, eventually, the compressor or other parts may wear out.
Can you put ice in an electric cooler?
Yes. In fact, if you don’t have a way to power your electric cooler, you can just put ice in and use it as a regular cooler. But if you do have power, it’s better to avoid using ice since, as it melts, the excess moisture can reduce the efficiency of the insulation, thereby increasing the workload on the compressor or thermoelectric cooling system, plus making your food soggy and leak out of drains that might not be fully sealed. Ice trays for drinks are an exception since the ice is neatly contained. Some electric coolers even include ice makers.
