I Put an I Cube Machine in My RV for a Full Summer

There is a specific kind of misery found at the bottom of a camping cooler. It is the gray, lukewarm slush that happens when a ten-dollar bag of gas station ice gives up the ghost three hours into a heatwave. Last July, after fishing a soggy, water-logged package of expensive bacon out of the 'cooler soup' for the third time, I decided I was done. I bought a dedicated i cube machine and bolted it—figuratively—to my RV countertop for a three-month trial.

Quick Takeaways

  • Produces solid, clear cubes that last twice as long as 'bullet' ice in a drink.
  • Requires about 120W of steady power, but watch out for the 500W compressor surge.
  • The footprint is about the size of a large toaster, but you need 6 inches of clearance for the fan.
  • It eats through your fresh water tank faster than you think—plan for a gallon a day.

The Gas Station Ice Run Was Ruining My Weekends

Buying ice at a campground is a racket. You pay a premium for a bag that has already started melting in the reach-in freezer, and by the time you walk it back to your site, you are carrying a bag of disappointment. In my 22-foot trailer, space is a currency. Using half my cooler capacity just to store ice that was actively destroying my food felt like a losing battle.

I spent years thinking a countertop appliance was too 'glam' for real camping. I was wrong. The constant cycle of driving to the camp store, hauling 20-pound bags, and draining the cooler every morning was a chore that ate my relaxation time. I wanted a way to produce ice on demand without leaving the shade of my awning.

Why I Decided to Try an I Cube Machine on the Road

The transition from a passive cooler to an active appliance is a big jump for any RVer. I was hesitant about the counter space. My dinette table is where I work, eat, and prep dinner, so adding a compact portable ice maker felt like a risky move for my workflow. However, the math started to make sense once I realized I could reclaim nearly four cubic feet of cooler space by switching to a small fridge and an on-demand ice source.

Power Draw vs. Solar Panels

If you are boondocking, the power specs matter more than the ice shape. My unit pulled about 1.2 amps at 120V while the compressor was running. On my 400W solar setup, this was manageable during the day, but you have to be careful with your battery bank at night. The compressor surge is the real killer—it can spike briefly when it starts a cycle, which might trip smaller 500W inverters if you are also running a blender or a vacuum.

Space Limits in a Tiny Kitchen

Ventilation is the one thing the manual warns you about that you actually need to listen to. These machines work by pulling heat out of the water and dumping it into your kitchen. If you tuck it into a tight corner, the ice-making cycle slows down from 15 minutes to 25 minutes because the unit is suffocating. I found that a sleek black ice maker looked great with my interior, but I had to pull it out from the wall every time I hit the 'start' button to keep the airflow moving.

The 30-Day Road Test: Does It Actually Work?

I ran this machine through a humid August in the Carolinas. Here is the reality: the first batch of ice is always a bit pathetic. The evaporator plate needs time to get down to temperature. By the third cycle, however, it was dropping heavy, crystal-clear sheets of ice. This is where the 'i cube' style wins over the cheap bullet-shaped machines. I wrote a whole breakdown on why dense solid cubes melt slower, and in a 90-degree camper, that density is the difference between a cold drink and a watery mess.

The machine produced about 20 pounds of ice in a 24-hour period during my testing. In the real world, that meant I could fill a small insulated bag every morning for the day's drinks. The noise is a steady hum, similar to a modern dishwasher. It is noticeable in a quiet RV at night, so I eventually learned to run it only during the day when the solar panels were soaking up the sun anyway.

The Hidden Costs of Running It Off-Grid

Ice is just frozen water, but when you are relying on a 40-gallon fresh tank, that water has a price. I found myself refilling the machine's reservoir twice a day. If you are not hooked up to city water, you are essentially drinking your shower water in the form of ice cubes. You also have to consider the financial side; I spent some time tracking the true cost of making ice versus buying it, and while the machine pays for itself in two seasons, the convenience is the real ROI.

Final Verdict: Who Actually Needs One of These?

If you only camp at sites with full hookups, this is a no-brainer. It is cheaper and more convenient than the camp store. For the off-grid crowd, it is a luxury that requires a solid battery setup and a healthy water supply. After a full summer, I am not giving mine up. The ability to have a glass of iced coffee at a remote trailhead without worrying about 'cooler soup' is worth every inch of counter space.

FAQ

Does the ice stay frozen in the basket?

No. Most portable units are not freezers. They are insulated, but the ice will slowly melt and the water will drip back into the reservoir to be recycled. You need to move the ice to your actual freezer if you want to keep it long-term.

How do you clean it in an RV?

I run a 50/50 mix of water and white vinegar through a cycle once a month. Since RV water can sometimes have a high mineral content, you have to watch for scale buildup on the sensors, or the machine will think the bin is full when it is empty.

Can I leave it on while driving?

I wouldn't. The water in the reservoir will slosh around and potentially soak the internal electronics. Empty the tank and secure the unit on the floor or in a padded cabinet before you hit the road.
