Ten portable machines later, my short answer is that the best ice makers for RVs fall into two groups: fast nugget ice for anyone who drinks a lot of water and soda, and simple bullet cube makers for everyone else. The Silonn nugget machine at number one on this list makes up to 36 lbs of chewable ice in 24 hours from a body that measures 11.3 inches wide, which is the rare combination of output and footprint that makes sense in a galley. Below it you will find nine more options covering small kitchens, narrow counters, quiet operation and low power draw.
Are portable ice makers any good? Yes, with one condition you need to understand before buying. They are excellent at producing ice on demand for drinks and they cost a fraction of what a built-in RV refrigerator ice maker takes to service. They do not store ice. The basket is insulated rather than refrigerated, so anything sitting in it for more than an hour or two turns back into water that drains into the reservoir for another run. Owners on The RV Forum describe the same routine they settled on: plug the unit into shore power, set it on an outside table, and dump each harvest into a bag in your fridge freezer.
That last point matters because it also means a portable unit reclaims freezer space rather than taking it, which is why several owners moved away from a failed Dometic ice maker and never went back. If you want a broader look at the category, our roundup of the best portable ice makers for RVs tested and reviewed covers the trade-off between an ice maker and a powered cooler in more detail.
I spent a six-week window working through the specs, owner reviews and power draw of every unit below while planning how ice would actually be used on a two-week desert trip with four people. Everything in this guide comes from published specifications and what owners report after living with the machines.

1. Silonn Nugget Ice Maker SLIM17T-PRO – Best Overall Ice Maker for an RV
Silonn Nugget Ice Maker Countertop, Pellet Ice Machine with Self-Cleaning Function, Sonic Ice Maker Produces 36lbs of Chewable Ice in 24 Hours, Ideal for Home Kitchen and Office (Stainless Steel)
36 lbs per 24 hours
Nugget ice in about 6 minutes
160W at 120V
11.3 in wide
Pros
- Highest output in this group at 36 lbs per 24 hours
- Compact 11.3 in wide footprint suits RV cabinets
- Removable top cover exposes corners for manual cleaning
- Self-cleaning cycle
- Quiet running for a sonic machine
Cons
- Indicator lights are the only status feedback with no display
- Water must be added by hand with no plumbed line option
Most ice makers in this category make bullet cubes, and bullet cubes are hollow with a hole down the middle. That hole is why they disappear in twenty minutes in a July campground. This Silonn model makes nugget ice instead, compacted from layered flakes, and the difference is immediately obvious the moment it hits a glass of water.
The spec that convinced me is the combination of 36 lbs of daily output with a body that measures 11.3 inches wide by 8.66 inches deep by 12.68 inches tall. That footprint fits alongside a sink in a galley where many 26 lb machines will not, and the machine is built to sit planted on a counter while a coach is moving.
Owners consistently report a first batch in about six minutes and running quietly enough to sit in a living space overnight, which matters in a small motorhome where the galley adjoins the bedroom. The removable top cover is the feature I would not trade. You can lift it off and wipe every corner of the freezing chamber, which is the difference between clean-tasting ice after a month on the road and ice that tastes of whatever was in the reservoir three harvests ago.
The catch is feedback. This unit gives you multi-color indicator lights and nothing else, so there is no display telling you how many pounds are in the basket or how full the reservoir is. You learn the machine’s rhythm after a few days and it stops mattering, but if you like knowing numbers, that is an adjustment.
Why this one works in an RV galley
It draws 160W on standard 120V power, which is a modest load next to a portable air conditioner for RVs running at the same time. On a 30 amp shore power connection you can run the ice maker, the coffee maker and a laptop without thinking about it.
Even at half its rated 36 lbs per day, four people drinking two cold drinks an hour would empty the basket several times over. Plan on a freezer bag within arm’s reach of the unit rather than an ice bin.
Where it falls short
The water reservoir is filled by hand every cycle or two on a hot day, and there is no plumbed line option, so nobody has rigged this unit to a fresh tank. Budget for the labour of topping up, especially with a group.
Water-level sensing is the most common complaint in reviews, so check the reservoir before a long afternoon rather than after. Everything in the box is ice maker, scoop, basket and manual, so keep the scoop somewhere it will not disappear into a cabinet.
2. Frigidaire EFIC128AMZBLK – Most Versatile Pick With the Clearest View of the Ice
FRIGIDAIRE EFIC128AMZBLK Compact Countertop Ice Maker, 26 lb per Day, Black
26 lbs per 24 hours
9 cubes per 5-6 minute cycle
105W at 120V
Large viewing window
Pros
- Large transparent window shows ice level at a glance
- Only 105W so it sips power
- Recycles melted ice back into the reservoir
- Alerts for full basket and low water
- Recognizable brand with a broad service footprint
Cons
- 14.5 in tall and bulkier than most portable units
- Built to make ice rather than store it
A 4.4 average across more than 16,000 ratings puts this Frigidaire among the most proven machines in the category, and the reason is that it does one simple thing without fuss. It makes nine bullet cubes every five to six minutes and totals 26 lbs per 24 hours.
The viewing window is the feature I would underline for RV use. On a unit with no display, being able to glance across the counter and see how full the basket is removes the single most common point of frustration in an appliance this size.
At 105W it draws less than half what the COWSAR on this list pulls, and the machine is made by CURTIS for Frigidaire, so parts and service questions have an obvious place to go. Melt water in the basket drains back to the reservoir and gets re-frozen, so nothing is wasted between batches.
The measurement that gives me pause is height. At 14.5 inches tall and 12 inches deep, this is one of the larger bodies here, and it needs clear space above it for the lid. Plan the cabinet before you plan the color.
Best for travel trailers with a tall cabinet
If your galley has a tall upper cabinet and you want ice visible at all times, this shape works better than a short wide unit. The dark black body also suits an RV interior better than the white plastic most competitors use.
Bullet cubes crush easily, which is genuinely useful for blended drinks and cocktails, and reviewers note that melt-back into the reservoir keeps waste near zero.
Where it falls short
Same warning as every other portable machine here: ice is made, not stored. Get each harvest into a freezer bag or a cooler promptly or you will be drinking room-temperature cubes by evening.
There is no ice size selector listed for this variant, so you get one cube size. If texture variety matters to you, look at a two-size model instead.
3. EUHOMY IM001-B – Best Value Bullet Ice Maker
EUHOMY Countertop Ice Maker Machine with Handle, 26lbs in 24Hrs, 9 Ice Cubes Ready in 6 Mins, Auto-Cleaning Portable Ice Maker with Basket and Scoop, for Home/Kitchen/Camping/RV. (Black)
26 lbs per 24 hours
9 cubes in 6 minutes
Under 45 dB
12.9 lb with handle
Pros
- Category best seller with more than 16000 ratings
- Under 45 dB is quiet enough for a sleeping RV
- 12.9 lb with a sturdy carry handle
- One-touch 30-minute self-cleaning cycle
- 12-month warranty with lifetime technical support
Cons
- 1.2 L tank means manual refilling rather than a plumbed line
- Hollow bullet cubes melt faster than nugget ice
This is the machine that shows up most often in RV owner threads, and one r/RVLiving owner reports running the EUHOMY 26 lb unit in their motorhome for about a year with good results. It ranks first in its appliance category on Amazon, so the volume of long-term feedback behind it is genuinely unusual for a product at this level.
It weighs 12.9 lb and has a real carry handle, which sounds minor until you are moving a full water tank across a wet floor in a travel trailer. The infrared sensor and the ICE FULL and ADD WATER indicators let it run hands-free, which is how you get ice while you are doing something else.
Noise is the underrated spec here. Under 45 dB means the compressor cycle is quieter than a small freezer, so running it overnight while you sleep does not require planning around it. Owners who measure their own setups tend to find this one among the more discreet.
The 170W compressor uses about 4kWh per 24 hours at full tilt, so a power station in the 1000Wh class covers a full day of production without a fuss. More on power sizing below.
What owners like most
The 30-minute self-cleaning cycle takes one button hold, and dishwasher-friendly pieces mean a full sanitation pass takes minutes rather than an evening. That matters more on a two-week trip than it does at home.
Multiple owners independently report roughly seven minutes to first cubes and a realistic 26 lbs per day, which matches the number on the box. That agreement across reviews is worth more to me than any single dramatic claim.
Where it falls short
The basket holds about 1.3 lb at a time, so on a hot afternoon you are emptying it repeatedly. Water-level sensor misreads show up in reviews often enough to keep an eye on the reservoir window.
Bullet cubes are hollow and melt quicker than solid nugget ice. If your group works outdoors in direct sun, expect more trips to the cooler.
4. EUHOMY Nugget Ice Maker IM002-12SXX – Best Nugget Ice on a Smaller Ice Basket
EUHOMY Nugget Ice Maker Countertop with Handle, Ready in 6 Mins, 34lbs Per Day, Removable Top Cover, Auto-Cleaning, Portable Sonic Ice Maker with Basket and Scoop, for Home/Party/RV/Camping (Black)
34 lbs per 24 hours
Nugget ice in 6 minutes
144W at 115V
1.2 Qt water tank
Pros
- Nugget ice ready in as little as 6 minutes
- Compact 9.45 in wide body with a built-in handle
- 1.8 lb removable basket with a viewing window
- Under 45 dB
- One-touch operation with clear water and full alerts
Cons
- 1.8 lb basket needs frequent emptying on heavy use
- Only 111 ratings so long-term durability feedback is limited
At 4.6 across its ratings this machine holds the highest average in this group, but the sample is small at 111 ratings, so treat the number with the caution it deserves. What the early owners do describe is a well-built machine that puts out 34 lbs of small pellet ice per day and does it in about six minutes.
The 1.8 lb basket is larger than the 1.3 lb baskets on several bullet machines here, which reduces the number of times you walk over to it. That single change matters more during a busy afternoon than the difference between 34 and 36 lbs of theoretical daily output.
Unlike the Silonn at number one, this unit has no customer images in the review data, so I cannot point you to owner photos of the interior. Early reviewers do highlight the lift-up top that makes manual cleaning straightforward.
Why nugget ice suits an RV
Nugget ice is denser and slower melting than hollow bullet cubes, so it holds together in a glass on a hot deck. It also drinks better, which matters on a long travel day.
At 144W it draws less than several of the bullet machines here, including the 170W and 160W models. A mid-size portable power station will run it comfortably for a full day of production.
Where it falls short
With 111 ratings, there is very little evidence about how this machine behaves after two seasons of hard use. Read recent reviews rather than settling in early, because that is exactly where quality drift shows up.
Nuggets are small and airy, which means a 1.8 lb basket disappears quickly with a family. And there is no plumbing option, so the tank gets filled by hand.
5. Silonn SLIM21 – Best for Small RV Kitchens
Silonn Ice Maker Countertop, Portable Ice Machine with Carry Handle, Self-Cleaning Ice Makers with Basket and Scoop, 9 Cubes in 6 Mins, 26 lbs per Day, Ideal for Home, Kitchen, Camping, RV
26 lbs per 24 hours
9 cubes in 6 minutes
160W at 120V
8.7 in deep
Pros
- Compact 8.7 x 11.4 x 11.6 in body fits small counters
- 13.7 lb with a sturdy carry handle
- Scoop and basket included in the box
- Choice of small or large cubes
- 30-minute self-cleaning cycle
Cons
- Only 1.3 lb of ice storage at a time
- Reservoir must be refilled by hand with no plumbing option
The Silonn SLIM21 is the pick for the RV with a counter that simply runs out of room. At 8.7 by 11.4 by 11.6 inches it fits small counters and kitchen islands easily, and it still delivers the full 26 lbs per day that most buyers expect.
A simple three-step control panel gives you small or large cubes, which covers a whiskey night and a fast-drinking iced coffee with the same machine. It comes with a one-year manufacturer warranty, and the handle is properly attached rather than a plastic tab.
At 160W this shares the electrical profile of the Silonn nugget machine at number one, which simplifies power planning if you own both. The polypropylene shell keeps the weight manageable and the footprint small.
The limitation everyone mentions is basket capacity. At 1.3 lb, the machine stops and waits for you well before the daily output figure suggests it should. On a mild morning that is a non-issue; on a hot afternoon with four people it becomes a job.
Good fit for a weekend rig
If you camp weekends and mostly want ice for canned drinks and coolers, this does the job without taking a real estate fight with your sink. It is also easy to stow between trips, so it does not live on the counter permanently.
Reviewers highlight the carry handle, the size and the ease of the cleaning cycle as the three things that made it stick. Those are the qualities that matter when the machine lives in a small space.
Where it falls short
Hand refilling only, so if you plan to run it all afternoon with a group, the reservoir top-ups are part of your routine. No plumbing hookup is available.
Small basket plus hollow bullet cubes means the most frequent harvesting of any machine here. Check the freezer bag before you leave it running.
6. Igloo IGLICEB26HNBK – Best Stainless Steel Body for an RV Galley
Igloo Premium Self-Cleaning Countertop Ice Maker Machine, Handled Portable Ice Maker, Produces 26 lbs. in 24 hrs. with Ice Cubes Ready in 6-8 Minutes, Comes with Ice Scoop and Basket
26 lbs per 24 hours
2-quart water tank
105W at 120V
Stainless steel body
Pros
- Stainless steel exterior suits an RV galley better than plastic
- 2-quart tank runs longer between refills than most
- Attached carry handle
- Automatic five-cycle cleaning
- 105W low draw
Cons
- First cycle takes 6-8 minutes rather than 6
- No ice cube size selection listed for this variant
Several machines in this category have a plastic shell, which is why the Igloo stands out in a galley. Stainless steel wipes clean without staining, survives a knock from a stowed duffel, and looks like an appliance rather than a novelty.
The 2-quart water tank is the second reason to look here. Most of the compact units here hold around 1.2 L, so the Igloo roughly adds 60 percent more run time between refills, which is a real advantage on a long desert afternoon.
Owners rate the automatic five-cycle cleaning function highly because it does the tedious part without you. At 105W, this machine pulls about half of what several plastic units here use, so it is easy on a small power station or a campsite pedestal.
First cubes arrive in 6 to 8 minutes. That two-minute gap against the fastest machines here is real but modest, and it only matters if you are waiting on a single drink.
Why the finish matters in an RV
A galley is a small, wet, high-traffic space. Stainless tolerates the splash, the vibration and the cleaning far better than painted plastic, which yellows and cracks after a season of sun through the window.
Reviewers note that cubes can melt in the basket if left more than an hour or two, which is the standard behavior for insulated storage. Plan the transfer to your freezer bag as part of the harvest.
Where it falls short
No ice size selection is listed for this variant, so you get one cube size. If you want small and large options, the two models on this list that offer both do it better.
The 12.8-inch height and 12.2-inch depth need measuring. It is not the smallest body here, though the stainless finish offsets the bulk visually.
7. COWSAR HZB-12U – Best for Narrow Countertops
COWSAR Ice Maker Countertop, Portable Ice Machine with Self-Cleaning, 26 lbs/24Hrs, 8 Cubes in 6 Mins, Quiet Compact Commercial Ice Maker for Kitchen, RV, Camping
26 lbs per 24 hours
8 cubes in 6 minutes
230W at 115V
6.69 in deep
Pros
- Only 6.69 in deep
- the shallowest body in this group
- Two cube sizes
- Quiet at roughly 40 dB
- Touch controls with an automatic cleaning function
- ETL certified for home and light commercial use
Cons
- Highest power draw here at 230W
- Only 1.1 lb of visible storage
- Small 0.8 L tank means frequent refills
- Ice can pile in front of the full sensor and stop it early
Depth is the dimension that kills most RV installs, and the COWSAR is built around solving it. At 6.69 inches deep and 12.2 inches long, it slides into a shallow counter run or a cabinet slot where a 12-inch-deep machine simply will not fit.
The manufacturer rates it for home and light commercial use, which tells you something about the compressor and the cycle time. Eight cubes land in the basket in six minutes, with two sizes available through the touch panel.
The 230W draw is the highest in this group by a wide margin, roughly double the Frigidaire or the Igloo. On shore power that is irrelevant. Off grid, budget for it or size your power station accordingly.
The narrow body is also why the internal tank is only 0.8 L. The design takes the depth out of the machine and puts it into height, which is the trade every shallow-cabinet owner makes knowingly.
Where the shallow cabinet makes it worthwhile
Travel trailers and Class B vans frequently have a counter that is 8 to 10 inches deep with a lip against a wall. This is the machine for that layout, and it is tall and narrow rather than short and wide.
Roughly 40 dB keeps it in the range you can run while sleeping, and the automatic cleaning function is a single touch.
Where it falls short
The short sensor arm lets ice stack in front of the full sensor, and the machine stops producing while the basket still looks partly empty. Rotate the basket or pull a handful out when you see a pile forming.
Durability complaints after several months of use appear in reviews, so treat this as a lighter-duty option if you run it hard every day. The 1.1 lb bin needs frequent attention for the same reason.
8. EUHOMY IM013-NSI Pebble Maker – Best Crunchy Nugget Texture
EUHOMY Nugget Ice Maker Countertop, Ready in 7 Mins, 35Lbs/24H Pebble Ice Maker Machine, Self-Cleaning Countertop Sonic Ice Makers with Ice Scoop&Basket, Pellet Ice Maker for Home, Stainless Steel
35 lbs per 24 hours
Nugget ice in 7 minutes
130W at 115V
11 x 9.1 x 12.6 in
Pros
- Soft crunchy slow-melting nugget ice reviewers compare to restaurant quality
- Stainless steel body at 11 x 9.1 x 12.6 in
- Removable parts are dishwasher friendly
- Automatic deep cleaning on a five-second hold
- Low 130W draw
Cons
- Some owners report it is louder than advertised
- Ice can block the inlet without a stirrer
- Basket drains through a few holes so water pools underneath
- Hand filling only with a 1.1 L tank
At 4.0 across more than 5,000 ratings this machine has the lowest average in the group, and I would rather explain why than skip it. The ice quality draws real praise. The complaints cluster around noise and an inlet that blocks.
Output is 35 lbs per 24 hours of crunchy nugget ice in about seven minutes from a stainless steel body measuring 11 by 9.1 by 12.6 inches. That texture is the reason to consider it. Owners compare it to soda fountain ice, and the slow melt is genuine.
The dishwasher-friendly removable parts make this the easiest machine here to sanitize properly on a trip, which is a bigger deal than it sounds when the reservoir is warm and the ice has been sitting for days.
The 130W draw is lower than the sonic machine at number one, so it costs less to run hour for hour even with its higher stated capacity.
Good for iced coffee and slow sipping
Dense nugget ice changes the drink. Water, iced coffee and anything you sip over an hour benefit from a cube that holds together instead of dissolving into the first sip.
The stainless body suits an RV interior and wipes down easily after a dusty campsite. Automatic deep cleaning runs on a five-second button hold.
Where it falls short
Several owners say it runs louder than advertised, in the territory of a mini fridge rather than a small compressor appliance. In a sleeping RV, test it where you plan to run it.
If ice piles up against the inlet, production stops until you stir or lift the basket. The drainage holes also leave a little water pooling underneath.
9. Crzoe HZB-12/Q – Best Basic Model for Beginners
Crzoe Countertop Ice Maker, 26Lbs/24H,2 Sizes of Ice, Self-Cleaning,Black
26 lbs per 24 hours
Two cube sizes
87W at 120V
Under 40 dB
Pros
- 4.5 average with 77 percent five-star ratings
- Quiet at under 40 dB
- 87W is among the lowest draws here
- Compact 11.77 lb body with a built-in handle
- Scoop holder on the basket
Cons
- Some owners report early failures to form cubes before descaling
- Ice must be moved to a freezer because the basket does not hold it frozen
The Crzoe is the one I would hand to a first-time RV ice maker owner. It has a 4.5 average with 77 percent five-star ratings, an 87W draw that is among the lowest here, and a control scheme that does exactly one thing without asking you to learn anything.
Eight bullet cubes land in six to twelve minutes, with two sizes available. The 11.77 lb body with a built-in handle moves easily between the counter and an outside table on a campground pad.
The scoop holder on the basket is a small, sensible detail. In a moving coach, a loose scoop ends up under a cabinet or behind the fridge, and the machine works fine without it.
One piece of advice appears often enough to repeat here: run a descaling cycle before first use. Owners who skip it sometimes report a unit that will not form cubes at all in the first week.
Why it suits new owners
Under 40 dB means it will not disturb a sleeping cabin, and 87W at 120V is a small fraction of what a portable air conditioner for RVs pulls, so you can run both off one shore power connection.
The two cube sizes cover most drink preferences, and the R600a compressor is efficient across the board. Nothing about it is specialized.
Where it falls short
The pre-use descaling step is not optional in practice. Without it, some machines simply do not produce, and the failure looks like a dead machine when it is not.
Ice is not held frozen in the basket. It needs a freezer bag or cooler within a short walk of the unit.
10. Antarctic Star HZB-12/Q – Best Low-Power Pick
Antarctic Star Countertop Ice Maker Machine, 26Lbs/Day Fastest 6‑Min Ice
26 lbs per 24 hours
8 cubes in 6 minutes
88W at 110V
Under 40 dB
Pros
- 88W is among the lowest draws in this group
- Quiet under 40 dB
- Compact 8.66 x 10.39 x 11.22 in footprint marketed for RV use
- One-touch self-cleaning cycle
- Two ice sizes with handle and basket included
Cons
- Plastic construction rather than stainless steel
- Small ice basket means frequent emptying
If your power budget is the deciding factor, the Antarctic Star is the number to work from. At 88W it sits at the bottom of the power range in this group, and the motor is engineered to cut energy use by roughly 30 percent compared with a conventional design.
Everything else about it is competent: 26 lbs per 24 hours, eight bullet cubes in six minutes, under 40 dB, and two sizes selected from the panel. The listing is marketed directly at RV, tailgate and cabana use, and the 8.66 by 10.39 by 11.22 inch footprint supports that.
Running the numbers on a smaller power station is where this machine earns its place. A 500Wh station has far more headroom for ice production at 88W than at 170W, and that headroom is what decides whether you make ice all evening or watch it slow down.
The self-cleaning cycle is recommended weekly, or after two weeks sitting unused, which is a sensible schedule for an intermittent user who does not run the machine every trip.
Best fit for lighter electrical setups
Boondockers running a smaller battery bank should look at draw before anything else. At 88W this machine coexists comfortably with a fan, a laptop and lights, where a 230W machine forces a choice.
The 4.1 average is the second lowest here, and the recurring notes are predictable: plastic build and a basket that needs emptying often.
Where it falls short
Plastic construction is the main compromise, and in a galley that gets splashed and knocked around, that matters more than the spec sheet suggests.
Small basket capacity is the other one. On a hot day with more than two people drinking constantly, you will be standing over it.
Are Portable Ice Makers Worth It in an RV?
Yes, if your goal is a steady stream of ice for drinks, and no, if your goal is to freeze a cooler down for a group of six. Every portable unit in this guide makes ice well and stores ice badly, and understanding that line before you buy prevents most disappointment.
The upside is real. A portable unit frees the freezer instead of using it, so you are not trading precious frozen storage for ice production. It also works without plumbing, without a dedicated drain and without an install. Plug it in, fill the reservoir, and it runs.
The downside is labour. You refill the reservoir, empty the basket, and move ice into a freezer bag or a cooler. Several owners on The RV Forum describe exactly that loop, and they describe it as worthwhile rather than annoying, which tells you something.
Owners also stress that brand matters far less than features and price. Most of these machines share a compressor, an evaporator design and a basket layout, and differ mostly in badge, shell material and indicator lights.
How Portable Ice Makers Work
A portable ice maker is a small compressor refrigeration system, the same principle as your RV refrigerator, running in reverse for one job. Understanding the cycle explains almost every behaviour you will notice as an owner.
Water sits in a reservoir at the top of the machine.
A pump moves water over metal freezing tubes and it begins to freeze around them.
The refrigeration cycle reverses into a cooling phase and the formed ice drops into the basket below.
Melt water drains from the basket back into the reservoir so it can be re-frozen.
Once the basket is full, a sensor stops the cycle until you remove ice.
That fifth step is why every machine here stops after a harvest. The basket is insulated, not refrigerated, so ice left sitting for hours softens and drains back down. This is called melt-back and it is a design choice, not a defect.
Bullet cubes, square cubes and nugget ice
Bullet cubes are hollow and fast-melting, and they crush easily for blended drinks. Square cubes hold a little better. Nugget ice is compacted from layered flakes, chews cleanly and melts slowly, and it takes more energy to make, which is why sonic and pebble machines often pull more watts than the typical bullet model. Our guides to the best nugget ice makers and pellet ice makers go deeper on texture if you want to compare ice styles rather than machines.
Power Draw, Shore Power and Boondocking
Every machine in this roundup runs on 110-120V AC household power, and none of them runs on 12V DC directly. That is the single most important fact for anyone camping away from a pedestal, so plan a power source rather than a battery connection.
Rated draws across this group run from 87W on the Crzoe and Antarctic Star up to 230W on the COWSAR, with most clustering between 105W and 170W. Against a coffee maker, a microwave and a portable air conditioner for RVs, an ice maker in this range is one of the smaller loads in the coach.
On a 30 amp shore power connection there is no issue at all. Off grid, a 1000Wh portable power station covers a full day of ice production for any of the lower-draw machines, and owners running units off shore power report roughly 1.7 amps while making ice and about 2 amps during the harvest phase on smaller models.
Solar generators in the same 1000Wh class work fine for weekend trips. For a full week of production in desert heat, plan for two full battery cycles or bring a second unit.
If you genuinely need 12V-only operation, the honest answer is that none of the machines here delivers it. In that case a powered cooler holding bagged ice is the more practical setup.
The Melt-Back Problem and How to Manage Ice Storage
Melt-back is the single biggest adjustment new owners face. The basket keeps ice cold for a couple of hours, not overnight, and everything that sits in it eventually returns to the reservoir.
The routine that works, taken from owner reports, is simple. Keep a freezer bag open next to the machine, scoop each harvest straight into it, and move the bag to the fridge freezer. On an outside table at a campground, that is the whole system.
A second option is to skip storage and treat the machine as a drink-side appliance. If everyone at your site drinks their ice within a few minutes of it being made, melt-back never becomes a problem, and you have already avoided the freezer space argument entirely.
Several owners also note that a powered cooler does something a portable ice maker cannot: it holds ice cold for hours. For a group that wants cold drinks at any hour, that is a different tool, not a worse one.
How Much Ice Do You Actually Need?
Map output to people rather than trusting the box. Each person drinks roughly one to two iced drinks an hour outdoors in warm weather, and ice counts for about 1.5 pounds per person per day under those conditions.
For two people that is around 3 lbs a day, which every machine here covers many times over. For four people it is closer to 6 lbs a day, still well under the 26 lbs claimed by most of these units.
The gap opens up when you try to fill coolers. A 40-quart cooler packed with drinks runs to roughly 25 to 30 lbs of ice to load solid, which is a full day’s theoretical output from one machine and several hours of harvesting in practice.
So the realistic verdict: a portable unit comfortably covers drinks for a family of four all day, and it is not a substitute for bagged ice when you are loading coolers for eight people.
Seven Features to Check Before You Buy
Check these seven things in this order and you will not regret the purchase. The first three kill more RV installs than anything else.
Footprint. Measure the counter depth and the clearance above it before choosing a model. Depth ranges from 6.69 in to 12 in in this group, and the tall narrow machines solve shallow counters.
Weight and handle. Machines here weigh roughly 11.77 to 13.7 lb when the listed weight is available, and a proper attached handle makes a full tank manageable on a wet floor.
Daily output. Anything from 26 lbs per day suits up to about four people for drinks. Numbers above that mostly describe ideal-condition testing.
Power draw. Match the wattage to your setup. Machines under 100W are the easiest to run off a smaller power station; 230W models need real headroom.
Basket indicator and shut-off. A full-basket sensor plus low-water alerts let the machine run hands-free. Machines that stop early when ice piles in front of the sensor will test your patience.
Ice size and type. Two sizes is genuinely useful. Nugget ice melts slower and costs more watts; hollow bullet cubes are cheap to make and vanish quickly.
Cleanability. Look for a self-cleaning cycle, a removable top and dishwasher-friendly parts. In an RV you will be cleaning it more often than you expect.
Cleaning and Maintenance While You Travel
A dirty ice maker tastes dirty, and on a two-week trip you will not want to deep-clean mid-route. A short weekly routine prevents that entirely.
Empty the basket and dump the old ice rather than topping it up.
Run the self-cleaning cycle, which is a button hold on every machine here.
Wipe the freezing chamber and the reservoir lid with a mild solution.
Check the water sensor float and wipe it if the machine misreads the level.
Run a descaling cycle before the first use of a new unit and roughly every few months.
For storage while driving, drain the reservoir completely. Water left in a machine bouncing down the highway is how lines freeze or crack, and an empty unit is also lighter in a cabinet.
One reliability note worth acting on. Read recent reviews rather than the overall average, because owners on The RV Forum specifically flag quality drift on models they once recommended. A 4.5 average built over years can hide two recent bad seasons.
Frequently Asked Questions
What is the best portable ice maker for a motorhome?
For most Class A and Class C motorhomes the Silonn nugget maker at number one fits the balance of output and footprint, producing up to 36 lbs per 24 hours from a body 11.3 inches wide. Travel trailers with narrow counters should look at the shallow-depth models, and anyone who wants nugget texture without the highest draw should compare the pebble-style units.
What is the best ice machine for an RV?
The best ice maker for an RV is the one whose footprint fits your counter, whose power draw matches your setup and whose basket size suits your group. A 26 lbs per day bullet machine at 105W serves up to four people for drinks all day. A narrow 6.69-inch-deep model solves shallow cabinets, and a low-draw unit under 100W runs comfortably off a smaller power station.
Are portable ice makers any good?
Yes, with one condition: they make ice very well but they do not store it. The basket is insulated rather than refrigerated, so ice softens within a couple of hours and drains back to the reservoir. Owners get good results by scooping each harvest into a freezer bag or cooler. Used that way, a portable unit gives you a steady drink supply and gives your freezer space back.
What is the best portable ice maker for filling coolers?
Honestly, none of these units is the right tool for a group cooler. Loading a 40-quart cooler of drinks takes roughly 25 to 30 lbs of ice, which is a full day of theoretical output from one machine and many hours of harvesting. For coolers, a powered cooler holding bagged ice works far better. Use a portable ice maker for drinks, not for cooler loads.
How much power does a portable ice maker use?
Rated draws in this group range from 87W to 230W, with most between 105W and 170W. On a 30 amp shore power connection any of them is a minor load. Off grid, a 1000Wh portable power station or solar generator covers a full day of production for the lower-draw models. All machines here run on 110-120V AC, so none plugs directly into 12V DC.
Do portable ice makers keep ice frozen?
No. The basket is insulated, not refrigerated, which is the same reason these machines save you freezer space instead of taking it. Ice left in the basket softens within an hour or two and drains back into the water reservoir to be re-frozen. Scoop each harvest into a freezer bag or a cooler within a short walk of the machine.
The Best Ice Maker for RVs in 2026: Final Verdict
If you buy one machine from this roundup, buy the Silonn nugget maker at number one. It produces the most ice in this group, fits a galley that most competitors cannot, cleans properly with the top off, and the nugget texture holds up in hot weather where hollow cubes vanish.
Buy the EUHOMY IM001-B instead if you want the simplest machine with the most long-term owner feedback behind it, and the Crzoe if you want quiet operation under 40 dB and the lowest rated power draw here.
Whatever you choose, measure your counter depth first and plan where the ice goes once it is made. Those two details decide whether you enjoy the machine. If you are still building out the rest of your rig, our picks for composting toilets for RVs cover the other upgrade most full-timers prioritise after cold drinks.
