Quick Tips
Pre-freeze the box on shore power or your tow vehicle's 12V before you leave, so the compressor isn't fighting a warm cabinet on day one.
Ice making and cooling can't run at once on these units — make ice overnight, then switch back to cooling in the morning.
Use filtered or bottled water in the ice reservoir; campground tap water scales the maker fast and slows production.
Add a 100Ah LiFePO4 or plug-in battery if you boondock — ice cycles pull hard and will flatten a starter battery overnight.
EcoFlow GLACIER Portable Car Refrigerator (40 Qt, with Ice Maker)
Best for serious, frequent overlanders
EcoFlow GLACIER Portable Car Refrigerator (40 Qt, with Ice Maker)
Best for serious, frequent overlanders
What we like
- The 120W compressor drops 18 solid cubes in about 12 minutes, faster than anything else here.
- Dual zones run independently, so one side freezes while the other holds drinks at fridge temp.
- Vacuum insulation panels keep it cold longer and cut power draw versus standard foam.
- Build quality and quietness edge out comparable Dometic units, per owner reviews.
What we don't
- Ice making and cooling can't run at once, so batches have to be planned overnight.
- The plug-in battery and detachable wheels are sold separately and add up fast.
- It's the priciest unit here before you've added a single accessory.
This is the unit to buy if you want the decision made for you and never want to think about ice again. It does everything the others do, but faster and colder, and it's the one most full-timers end up keeping.
Pick this if you camp often enough that a premium fridge earns its keep over years. If you only get out a few weekends a season, the value picks below do the same job for less.
EcoFlow GLACIER with 298Wh Plug-in Battery (40 Qt, with Ice Maker)
Best for off-grid and boondocking
EcoFlow GLACIER with 298Wh Plug-in Battery (40 Qt, with Ice Maker)
Best for off-grid and boondocking
What we like
- The included 298Wh battery runs the fridge up to 40 hours of cooling with no shore power.
- It accepts up to 240W of solar, topping the battery in roughly two hours of sun.
- Same 18-cubes-in-12-minutes maker and dual-zone box as the base GLACIER.
- The battery doubles as a 100W USB-C bank for phones and laptops at camp.
What we don't
- You pay a steep premium over the base unit for the bundled battery.
- At 19 hours, hard-freeze runtime is far shorter than the 40-hour cooling figure.
- Total weight with the battery makes solo lifting into a tall rig awkward.
If your camping happens where there are no hookups, this is the version that actually works for you. The bundled battery keeps ice and cold food coming for over a day with the engine off and the sun doing the rest.
Choose this if you boondock, dry-camp, or want backup cold storage during outages. If you mostly park where there's shore power, save the money and get the base GLACIER instead.
EUHOMY 12 Volt Refrigerator with Ice Maker (48 Qt)
Best for families on a budget
EUHOMY 12 Volt Refrigerator with Ice Maker (48 Qt)
Best for families on a budget
What we like
- A 35QT fridge plus a 13QT ice maker gives you the most usable space per dollar here.
- App control sets temperature and ice speed from your phone over Bluetooth.
- Three-level battery protection cuts off before it drains your vehicle's starter battery.
- Wheels and a pull handle make it manageable to move when loaded.
What we don't
- Ice output of 6 cubes per 8-minute batch trails the EcoFlow's pace.
- The optional battery is frequently out of stock, limiting true off-grid use.
- It's a tall unit, so check your cargo height before buying.
If you want the most fridge and ice for your money, this is where the math lands. You get nearly the capacity of two coolers plus a built-in ice maker for a fraction of the premium units' price.
Best for families and longer trips where space matters more than the last word in ice speed. If you need true off-grid runtime, look at the battery-equipped picks instead, since EUHOMY's battery is hard to get.
STMHOM 40QT Car Refrigerator with Ice Maker
Best for tailgates and group camp
STMHOM 40QT Car Refrigerator with Ice Maker
Best for tailgates and group camp
What we like
- Four power modes — AC, DC, removable battery, and solar — cover almost any camp setup.
- The fold-up side handle doubles as a small prep table at the tailgate.
- A 120-cube basket and two cube sizes keep a group iced through the day.
- Rubber wheels and a low center of gravity make it easy to roll when full.
What we don't
- It's a lesser-known white-label brand, so long-term support is unproven.
- Ice making pauses cooling, like the others here.
- The removable battery is an extra purchase for off-grid runtime.
If your weekends are tailgates, river days, and group cookouts, the fold-out table and four power options earn their place. You can roll it up, flip the handle into a prep surface, and keep a crowd in cold drinks and fresh ice.
Pick this for social, stationary camp setups where flexibility beats brand prestige. If you want a proven name and the fastest cooling, the EcoFlow picks are the safer long-term buy.
VEVOR 12 Volt Car Refrigerator with Ice Maker (37 Qt)
Best for solo weekend trips
VEVOR 12 Volt Car Refrigerator with Ice Maker (37 Qt)
Best for solo weekend trips
What we like
- It's the lowest entry price here for a real compressor fridge that also makes ice.
- It still puts out about 13 pounds of ice a day in two cube sizes.
- A single 37QT compartment swallows 60 cans without wasted divider space.
- Casters and a folding handle keep a full box easy to move.
What we don't
- The single zone can't hold freezer and fridge temps at the same time.
- The door isn't reversible and there are no dedicated tie-down points.
- Temperature can wander and cycle more than premium units, per owners.
If you just want out of the ice-run cycle without spending premium money, this is the cheapest honest way to do it. It makes real ice and keeps food frozen off 12V, which is all most weekenders actually need.
Best for solo trips and short weekends where one compartment is plenty. If you need to freeze and refrigerate at the same time, step up to one of the dual-zone units above.
What to Look For
Compressor beats absorption for ice, every time. A 12V compressor fridge actually freezes, while the old absorption units in many RVs barely make cubes.
Read the ice spec in real units. Cubes-per-batch tells you more than vague daily-pound claims you'll never hit in summer heat.
Match power to where you camp. Shore-power campers can skip the battery; boondockers should budget for one from the start.
Who Should Skip This
Skip these if your RV already has a working residential fridge with an automatic ice maker plumbed in, since a portable unit just duplicates it. They're also overkill if you camp twice a year and a cooler with a bag of ice genuinely doesn't bother you.
And if every trip has full hookups, a cheaper standard 12V fridge plus a countertop ice maker can cost less.
What the Community Actually Uses
On r/overlanding the recurring advice is to treat the ice maker as a bonus, not the main job: buy for cooling performance and battery draw first, because a fridge that can't hold temp off 12V overnight makes its ice feature meaningless. The EcoFlow GLACIER comes up most often as the unit people keep, while the white-label 40QT makers get praised on price and side-eyed on long-term reliability.

EcoFlow GLACIER Portable Car Refrigerator (40 Qt, with Ice Maker)
Check Price on AmazonFrequently Asked Questions
Can these run off my RV battery without draining it?
On cooling, yes — most pull well under 1 kWh a day and include low-voltage cutoffs to protect your starter battery. Ice making spikes the draw far higher, so do it on shore power or a house battery. Making ice overnight off a single starter battery is a bad idea.
Why can't it make ice and stay cold at the same time?
On these units the compressor serves either the ice maker or the cooling box, not both at once. You run a batch of ice, then switch back to cooling. Plan ice in the evening so the fridge holds temp overnight.
How is this different from my RV's built-in fridge?
Most factory RV fridges are absorption units that cool slowly and rarely make usable ice. These are 12V compressor fridges that freeze hard and produce ice on demand. They're portable, so they move between rig, truck bed, and campsite.
Do I need the optional battery?
Only if you camp without shore power. On hookups, the AC or DC cord runs everything fine. For boondocking, a plug-in or house battery is what keeps ice and cold food going overnight.
Is the ice good enough for drinks, or just for cooling?
It's solid bullet or cube ice, fine for cocktails and coolers, not soft nugget ice. Most units offer two cube sizes. The EcoFlow's cubes come out the most consistent of the group.
Buying Guide
Decide first whether you run on shore power or off-grid, since that sets your battery needs. Match capacity to trip length, and read the ice spec in real terms: cubes per batch, not pounds per day.
Skip old absorption units; a 12V compressor freezes hard and makes ice almost anywhere.
