Propane used to be your only option. But battery tech keeps improving, and solar keeps getting cheaper. That's changing everything. Today, many newer RV models are now available with electric refrigerators, and more RV owners are choosing electric options. Walk into any dealership, and you'll see it. Thousands of older RV owners are switching, too.
How Do Electric RV Refrigerators Work?
Electric fridges work the same way as your home fridge, but they are made to be tougher so they can handle rough roads and parking lots.
The heat is pushed out, and cold is pulled in by a compressor that squeezes the refrigerant gas. These days, units work faster when they need to cool down more and slower when they don't. They use 30 to 50 amp-hours of electricity every day as they turn on and off by themselves.
12V Models Run Off Batteries
These hook up straight to the batteries in your RV. They can support extended off-grid camping with enough lithium batteries (200 amp-hours or more) and solar panels (300 watts or more).
Portable Models Change Everything
Some units, like the EcoFlow GLACIER Classic, have 298Wh batteries built in that can keep food cold for up to 43 hours without a power source. You can put them anywhere in your RV and charge them from the sun, your car, or an AC outlet—you don't have to change the wires.
120V Models Need Hookups
Some big trailers have fridges that look like those in homes. While these have a lot of room, they need to be plugged into the wall or powered by a generator or a big inverter system all the time.
What Are the Benefits of Electric RV Refrigerators?
Electric fridges fix the problems that propane users face every day.
Keeps Exact Temperatures: It stays at 38°F once you set it. High-end types like the EcoFlow GLACIER Classic keep their accuracy to within 1.8°F. Food stays fresh longer, ice cream stays frozen, and you never wonder if something is really cold.
Works Anywhere You Park: Do you park on a hill or rough ground? It doesn't matter. Electric fridges work great from any angle. You no longer have to waste time using bubble levels and leveling blocks to look for flat spots.
Handles Extreme Heat: Propane doesn't work well at 95°F. Even when it's 100°F, 110°F, or even 115°F outside, electric units still work well. The EcoFlow GLACIER Classic can work in temperatures ranging from 14°F to 122°F and keep its internal temperature stable.
Cools Down Fast: Electric fridges take two to four hours to reach the right temperature. You can get food, load the car, and drive off the same day. No more having to wait all night for things to cool down.
Dual-Zone Flexibility: Some more expensive models, like the EcoFlow GLACIER Classic (45L/55L), have different spaces for each item. Keep fresh food at 39°F and frozen food at -4°F at the same time, with a temperature range of up to 39.6°F. This is better than what any propane fridge can do.
What Are the Drawbacks of Electric RV Refrigerators?
Needs Battery Power: Built-in units need 200 amp-hours of lithium and solar panels, which costs between $2,000 and $4,000. This problem can be solved by portable choices like the EcoFlow GLACIER Classic, which has built-in 298Wh batteries that can cool for up to 43 hours.
Higher Upfront Cost: It costs between $900 and $1,500 to add electrical changes to a built-in 12V fridge. Portable units start at about $999 and come with a battery. They don't need to be installed.
Some Noise: Budget models hum and click. At less than 38.5 dB, which is about as loud as a library, high-end units like the EcoFlow GLACIER Classic are quieter.
How Do Propane RV Refrigerators Work?
Through a chemical absorption process, propane fridges cool by using heat. When a flame heats liquid in tubes that are closed off, the liquid turns into a gas, which pulls heat from inside and then turns back into liquid.
There are two kinds: 2-way units, which use propane and AC power, and 3-way units, which add 12V but quickly drain the batteries. Most RVers stay away from the 12V mode because it loses power.
What Are the Benefits of Propane Refrigerators?
Propane is helpful if you camp with few power outlets because:
Low battery draw - The settings only use 1-2 amps of power, so you can camp without solar panels if you want to.
Silent operation - Nothing loud, like a fan or humming, will be heard in your RV.
Long lifespan - Since there are no working parts, the burner will work for 20 years or more if it is cleaned once a year.
What Are the Drawbacks of Propane Refrigerators?
RVers are moving toward electric choices because propane has its limits:
Cools slowly and inconsistently - The temperature drops 30–40% in heat above 95°F and changes 10-15°F depending on the weather. It takes 8–12 hours to hit the right temperature.
Must stay level - If you tilt the $2,000 cooling unit more than 3 degrees, it will break. You have to use leveling tools to find flat spots.
Struggles at altitude - Above 8,000 feet, where the air is thinner, cooling drops by a lot.
Requires perfect airflow - Cooling drops 30–40% when outside vents are blocked, and performance is cut in half when spider webs are in the burner tubes.
Needs annual maintenance - Burners must be cleaned or efficiency drops.
Safety concerns - You must turn off propane appliances at every gas station when there is an open flame near fuel fumes.
How to Choose Between Electric and Propane RV Fridges
Match Your Power Setup: Minimal electrical system? Propane works, but you might want to look into small electric coolers that have batteries built in. Have 200Ah+ batteries and 300W+ solar? If you want better performance, go electric.
Consider Your Climate: Camp when the weather is mild (60 to 80°F)? Both of them work. Camp in 95°F+ heat? Electricity takes care of it, but propane has a hard time.
Think Portable: The EcoFlow GLACIER Classic has electric benefits without having to be rewired. It has two cooling zones, exact temperature control, can be used at any angle, and can handle very high temperatures. With a built-in battery, it costs $999, which is less than full electrical improvements but gives you better performance.

Make the Right Decision
Electric fridges solve the biggest propane problems: they cool faster, work at any angle, and handle extreme heat that makes propane units fail. Built-in models need electrical upgrades, but portable units with built-in batteries deliver the same performance without rewiring.
Propane still makes sense if you camp in mild weather with minimal electrical. But as batteries get cheaper and solar improves, more RVers choose electric for reliability and performance. Portable options like the EcoFlow GLACIER Classic make switching easier than ever—premium cooling without the electrical overhaul.
FAQ
Q1: How long does it take for an electric fridge to get cold compared to propane?
An electric fridge cools down in two to four hours from room temperature. Propane takes 8 to 12 hours. If you're leaving soon, electric will keep food cold fast, but you'll have to plan ahead with propane. In heat above 95°F, propane doesn't work very well, but electricity keeps the cool air going.
Q2: Can I run an electric RV fridge while driving?
Yes. Built-in 12V units can run off the batteries while you drive if your RV has a good alternator or DC-DC charger. Electric coolers that are portable and have batteries built in work great. They can run on their own and be charged from your car's 12V plug without drawing power from your RV's main battery.
Q3: Do I need to turn off my propane fridge when getting gas?
Yes, absolutely. All propane appliances near fuel vapors must be turned off at gas stops. You don't have to remember to turn off an electric fridge. Propane fridges stay cold for 4 to 6 hours with the door closed, so food won't go bad on short trips.
Q4: Which fridge type works better for weekend camping?
For weekends with hookups, electric gives you better temperature control and faster cooling. Off-grid depends on your power. Minimal batteries favor propane, but portable electric coolers with built-in batteries work 40+ hours and recharge from your car or solar without needing a full RV electrical system.
Q5: Will adding solar panels let me run an electric fridge off-grid?
You need both solar (300W minimum) and batteries (200+ amp-hours lithium). Solar only works during daylight, but fridges run 24/7—batteries store energy for nighttime. If you're not ready for full upgrades, portable electric coolers with built-in batteries add solar charging capability without rewiring your RV.
