Alpicool C20 Review
Today we will bring you the authoritative Alpicool C20 portable refrigerator review, and tell you how to use this car refrigerator, the pdf version of the manual introduces, including battery, watts, compressor, charging, solar energy and precautions instructions, so that you can use it quickly Alpicool C20L.
I like gadgets. And I like useful gadgets. Why not a portable refrigerator? Truckers use them. People who own smaller boats use them. People who boondock camp use them. Or how many times have you holiday driven home and thought it would be nice to have some cool drinks or lunch meat for sandwiches available so you aren’t eating expensive, just off the interstate, food. I drive quite a bit for work and live in hotels a bit as well. Now that we’ve identified a need let’s identify a product solution.
Enter the Alpicool C20 portable refrigerator/freezer.
That’s right, it is also a freezer. Cost new was $580, however, I must have caught that just right as it is now $509. I have a three-way (120v, 12vdc, gas) Dometic refrigerator in my camper. It sure is nice but it is NOT a freezer. I think we all know what happens to chicken and pork after 3 or 4 days in the refrigerator. If we go out in the woods for any amount of time we may need some method of freezing food unless we want to eat MRE’s. I do not.
If you have a mini-fridge in your bedroom or den for cold drinks, guess what? The Alpicool C20 draws less than half the electricity a mini-fridge does. That’s a good reason to have one as well.
Also, I spend quite a bit of time working on active military runways at Marine Corps and Naval Air Stations. It sure would be nice to have a tiny fridge full of cold water or Gatorade for those long, hot July afternoons. The Alpicool sits nicely in the back seat of my truck. And there is a 12vdc socket on the back of my armrest/console in my Tacoma. It’s like it was made for it.
The name C20 indicates that it has 20 cubic liters (21 quarts) of storage. That’s not tons of space but plenty of space if you utilize it correctly. After unboxing I took a quick look at the manual and it sure doesn’t say much. In fact, it doesn’t even tell you how to change from Celsius to Fahrenheit on the LED display. Mine did come set to Fahrenheit. A quick google reveals though that there are hidden menus available and the manufacturer will provide them upon request which isn’t really necessary because they are all over the internet now. Here are the hidden menus. Click the link below to download in pdf format:
Those hidden menus are a way to calibrate the temperature display with the actual temperature inside the unit. After doing lots of research and reading lots of reviews it seems like a lot of people note that the display is off a few degrees from reality. Once you plus or minus the temp in the hidden menus then it is dead on.
So that is the first thing I intend to do after I set the display from C to F.. I’m going to use a refrigerator thermometer to properly set the temperature. It’s very difficult to see however the indoor temp is just below 40 F and the outside display temp is 37 F. A couple of factors that play in here is that I just threw some warm cokes in, and I’ve just put the fridge thermometer inside. I’m going to let them stabilize just a while longer before I call it “good” or make an adjustment.
Alpicool C20 Temp inside vs. display
Then I’ll test it on my camper battery. I recently installed a 12vdc cigarette lighter power port in my camper for just this device. Even though the Alpicool C20 works on 120v, I plan on being out in the bush camping off-grid on only solar power and my 12-volt batteries.
Installation of USB sockets and 12 volt power port in my camper
Nice addition to the camper if I do say so myself and I'm not exactly sure why a “Solar Ready” camper wouldn’t have a 12-volt power port to power 12-volt appliances. Things that make you go “Hmmmmmmmm”.
If I were to run this device on my Jackery Explorer 500 Portable Power Station it would last approximately 9-10 hours were it to stay on constantly pulling 45 watts. Since it runs about 3 minutes every 20 mins or so this thing will probably easily last 24 hours or longer.
Power Consumption of Alpicool C20 on Jackery 500 if compressor ran constantly
So far the fridge is QUIET! Although I’d be willing to bet you the sound would be more prominent in the camper or when it is in a vehicle. Still, it is QUIET. Library quiet.
Once I get the cokes cooled down and make sure they don’t freeze or something then I’ll set this to freezer level and put some items in that you’d typically freeze and test that out. Then I’ll put it in the camper and see how the power draw goes. I currently have mine set to Economy (ECO) mode. It comes set to High by default.
Let’s take a look at the power draw while set in ECO. The data was captured from my Sonoff S31 flashed with Tasmota firmware. With the compressor NOT running it pulls about 2 watts when plugged into 120 volt outlet. When the compressor is on it pulls about 50 watts. I saw it hit 55 watts for just a second.
Power Consumption of Alpicool C20 – Compressor Off vs. Compressor On
After about a day of operation the highest wattage draw I’m seeing is about 47 watts with it generally running about 45 watts. Not a huge difference in power consumption reduction but maybe it is just the fact that the cooling box is cold and the compressor isn’t having to work so hard. But essentially after a day the wattage consumption dropped by about 10 watts.
“This could be the most important part. What does it cost to operate as a household appliance? It runs about 125 watts per day. @ 365 days a year and a utility rate of 12.16 cents per kWh it costs about $5.50 a YEAR to operate.”
0.125 x 365 = 45.625 kWh
45.625 x 0.1216 = 5.548
This also makes sense because the refrigerator I just bought for the garage has an energy star sticker that says it uses around 400 kWh per year at a cost of $48 per year. So it uses just over 1 kWh per day while the Alpicool uses roughly 1/10th of that. Also considering it will be in the truck and camper some of those 365 days means it will cost even less. Wouldn’t cost anything if I ran it off a Jackery power station and kept it charged with solar. Not sure it is cost effective to set up $300 worth of solar gear to save $5 a year though.
Let’s talk about what I like and what I don’t like
- Cools FAST
- Can also be a freezer
- Low power consumption in Eco mode
- No interior themometer
- Temp Display and actual internal temperature could show some disparity.
- Hidden menus which really should be in the manual.
After almost a full day of running with a handful of coke cans inside it appears that the refrigerator thermometer I placed inside the cooling compartment agrees with the LED display temperature. Both say 32 degrees F. They must have made some improvements in the design because as I mentioned earlier there were a lot of reviews mentioning the disparity in temps.
One other thing I have noticed is that if you are set to F it seems you can only change the temperature in 2 degree (1.8 degree) segments and it will only hit even numbers if they equal a Celsius number. For example If I set the fridge to 33 the next step is 35 or backwards to 32. I suspect that is because it is Chinese and based on the Celsius scale where a change in 1 degree C is about 1.8 degrees F. If you are familiar with Celsius you may be better off using it as it seems to be made for C with just conversions for F. For example:
- It can be set to 32 degrees because that equals 0 C
- The next step is 33 degrees as 1C = 33.8 F
- The next step is 35 as 2C = 35.6 C
In other words while it will display 1, 2, 3, 4, 5 C, etc. It will not display 34 because there is no C equivalent conversion. Hope that makes sense. If I want to set it just above freezing to keep beer or soda COLD but not frozen then 33 or more likely 35 is your Huckleberry.
Just for fun I’m doing an endurance test using my Jackery Explorer 500 portable power station as the power source using the 12vdc port.
I began the test at 5:15 PM, Friday using a fully charged Jackery 500 and with the fridge cooled to a setting of 35 degrees internally. At 11:15 PM the Jackery indicated 91% charge. Of course this would seem to imply the ability to run for about 60 hours but there are a lot of variables and I don’t want to run my power station down to zero. And I’ll use the fridge as normal and open and close it a few times during testing. Another thing to note is that my testing is indoors with an ambient temperature of 70 degrees F. Run endurance time would differ somewhat if the fridge were in very cold temperatures or very hot temperatures.
Test Results Day 1
- Begin at 5:15 PM – 100%
- 11:30 PM – 91%
- 5:15 AM – 80%
- 11:15 AM – 70%
- 5:15 PM – 61%
It seems the Alpicool C20 uses almost exactly 10% of the Jackery 500 battery supply every 6 hours on refrigerator.
- I missed the 11:15-11:30 PM check due to that unimportant thing called sleep.
- 5:15 AM – 38%. For the first time it seems it used slightly more than 10% per 6 hours. I was in and out of the fridge a bit yesterday shooting the video below which took a few takes. Still not too shabby.
- 11:15 AM 28% and then while I was standing there looking at it it dropped to 27% a minute later. Looks like it is going to easily make 48 hours with a little left to spare.
- 5:15 PM – 16% – as predicted 48 full hours with enough power left to charge some phones and iPads. I’m as impressed with the Jackery and I am the Alpicool.
Here’s a quick video overview
Maybe you need one of these, maybe you don’t. But I think it’s super cool. If you camp, drive a lot, or are a tailgate partier………..this is for you!

Review of the Alpicool C20 refrigerator freezer
The Alpicool C20 Portable Fridge is a great choice for those looking for a fridge freezer portable appliance.
Electrical Grid down disaster or on the road for a long road trip, the Alpicool C20 Portable Fridge is great for keeping your food fresh and your drinks cold!
The Alpicool is an "actual" compressor based refrigerator. Not a junk "heat exchanger" type refrigerator.
A "Must Have" for insulin dependent users or other injectables that need to be stored cool.
It's capable of being powered from 12V and 110V. Very low power consumption.
Reviews say an Alpicool will run for 3 days on a single 12V battery on Eco setting.
It has also been testing as a freezer successfully, but very high power consumption in this mode.
Honestly? When disaster strikes you can't live without ice cream or ice cubes?
Just the thing for grid down type disasters.
My own review of the Alpicool C20
To begin, this is a very impressive small, compressor based, refrigerator.20 quart capacity. Easily holds 12 bottles of water with room to spare.
It came well packaged with a 110 to 12 volt transformer and a cigarette lighter plug in cord.
I plan to just install alligator clips to connect to the battery direct. As an initial test I put a few items inside along with a digital thermometer.
Items were NOT pre-cooled so cooling will be MUCH slower than taking things out of your refrigerator and put them directly into the Alpicool.
Remember, the Alpicool not only had to cool itself but cool the warm items I put in it.
Simply plugged it into the wall and turned it on and setting the temp. at
-5 degree Celsius (23 degrees F). (Instructions below on how to change read out to Fahrenheit)
Room temp when test began was 78 degrees F.
1 hours later, inside of refrigerator was 50 degrees.
1.5 hours later, inside of refrigerator was 32 degrees.
Placing warm items inside slowed it down big time.
Maximum wattage draw I observed was 49 watts but that was only for 1/3 the time.
From another resource I found:
In Eco mode, set to -5 Celsius, it averaged about 6 watts an hour, using about 144 watts in 24 hours. (12AH per day)
A big plus is how quiet this refrigerator is. My laptop fan is louder.
My only complaint is how inaccurate the unit's temperature gauge is.
I was using a digital thermometer inside and I saw a 10 degree difference in the reading.
Higher temp. reading inside than was shown on the outside gauge.
Inside temp was reading 32 degrees F. Outside display was 23 degrees F.
My recommendation is use a thermometer inside until you get a feel for what your settings need to be to get the desired result.
However, my use of warm items had an effect on these readings and time it took to cool down.
Note: If you open the lid you'll get a false outside reading but it will return to normal.
The use of warm items inside had a HUGE effect on how fast the Alpicool cools down.
This morning I tried my empty Alpicool C20 with starting temp at 78 degrees.
Unit only took 30 minutes to reach 34 degrees.
I also set the Temperature Compensation at +6 and display is reading correctly now.(See "Hidden Settings below)
There is still a slight difference between the temperature you set and what you actually get, but you can just adjust up or down until you get the inside temperature you want.
In my case, I wanted 34F degrees inside but had to set the temperature at 38F degrees to get it.
I'm sure the temp setting you use will vary depending on how full the unit is.
At least now the readings are correct.
