F40C4TMP 12 Volt Refrigerator, 20 Quart(18L) Portable Freezer, 12V Car Fridge(-8℉~50℉), Compressor Cooler for Camping, Road Trip, Travel, Van, Truck, RV, Boat, Outdoor, Home, 12/24V DC & 100~240V AC

Bought this for road trips after wishing I had one for my last road trip. For the last several days in the meantime it's been supplying me with icy cold drinks next to my desk. I love this thing. No issues setting it up. I let it stand for 12 hours to allow the compressor to settle, then powered it up, set it to 2C (colder than my fridge) and threw a bunch of already cold drinks in it, which allowed it to reach 2C in around 25 minutes. Runs very quiet. I haven't noticed any temperature difference between the top and bottom of the cooler but I haven't measured it. Every drink feels the same icy cold temperature regardless of where they're located in the cooler. I noticed some photos of the interior posted in reviews here show a sort of fabric interior with a seam running down the inside but the one I got had a seamless solid plastic interior. Was quite happy about that. This thing is going to be fantastic for road trips. Can't wait.

I am over all very satisfied with this cooler. Its compressor is small of course so it doesn't cool super fast, but it is reasonably quick for its size, which also makes it very portable. The digital thermometer/thermostat is quite accurate and can even be set to cool below freezing so be careful unless you don't mind your drinks being frozen. It cannot be set quite cold enough for ice cream, though, which requires temperatures a ways below freezing to stay solid, so be aware. (Some ice cream does okay at its lowest -8F setting, but not all.) But it works excellently to keep food and beverages nice and cold. Its 20-quart capacity is on the smaller end which again makes it nice and portable, but still easily holds 2x 2-liter soda bottles with a bit of room to spare, and there are larger models for those who need more storage space. The compressor is actually much more quiet than I expected, though of course it still makes a bit of noise it is hardly noticeable. Overall an excellent product and highly recommended.

I got this, planning to use it while camping, in conjunction with a solar panel and a 160Wh battery. Since I'm going to be relying on it off the grid, I have been doing a bunch of testing to make sure that it will serve my needs. I have been testing it as a freezer only -- its performance as a refrigerator will certainly be different (and better!) First, a little nitpicky thing: the rubber seal over the USB port is completely inadequate. It doesn't seal (or even completely seat) at all. Because I don't want to risk debris or liquids getting into the port, I've just taped over the entire thing (I don't need to use it). This can easily keep things frozen -- but it's not great at freezing things that aren't! When trying to freeze a large freezer pack, it managed to get the pack down to about 3C without trouble, but below that, it starts to take a very, very long time (days). It is best used as a long-term sort of freezer: if you take something out of it and it warms up too much, you're much better off not putting it back in. I am able to get it down to -21C. The temperature readout indicates a lower temperature than it actually reaches, by about 5C. I haven't yet tested how long it can keep temperature when it's not being powered, but it seems like it will reasonably well -- I think it's a little worse than a good cooler on this count. I think that if you get the thermal cover to go with it, it will probably outperform a good cooler. That's just my expectation. I haven't tested it. I tested how long I can run it on the battery I'm using, with it set to -21C and to -10C (using a 160Wh battery, discharging it down to 10%), and with nothing at all in the cold chamber. At -21C, I can run it for about 6.5 hours. At -10C, I can run it for about 10.5 hours. These numbers don't change between "eco" and "max" modes. "Eco" mode does make the fridge use about half as much power as "max", but the compressor runs for about twice as long. If you're using this in a setup where you can't draw more than 30W or so, "eco" is your friend. Otherwise, it doesn't seem to matter much. Testing with it full of food is a completely different matter. My whole life, I've been told that any fridge/freezer is more energy efficient when its full, but I didn't realize how much of a difference this makes. When full of already frozen food, it can maintain that temperature for about twice as long on a charge. I really like this refrigerator a lot, and I think it will meet my needs easily. I can recommend it without hesitation, but think that expectations need to be adjusted: this is not like your home freezer, and performs poorly if you're freezing something that wasn't already frozen. However, as long as you can pre-chill the things you put into it, this performs excellently.

Well I read all the reviews before I purchased one... mine arrived quickly, I followed the start up directions and connected it to my Jackery 500 battery and 80 watt solar panel. The cooler is amazingly quiet, I set the temp for 18° and after awhile the temp inside hovered around 20°-24°...so yes the thermostat is a little off but jeez you can just set it about 5° lower than what you want. It will freeze water but takes all day, however I’m using it too it keep steaks and hamburger and eggs and cheese, chicken and milk and bacon ice cold without worrying about water logging. This cooler is fabulous for keeping these things cold. Inside temp was set at 34 and the Jackery never got down past 60% battery life and that’s with an electric blanket running all night on low as well. During the day my Jackery battery charged up to 100% before afternoon arrived. I kept the solar panel attached all the time, the cooler chest only stays on for about 15 minutes every 45 minutes on Max cool. Even on cloudy days it charged up to 100% and I never felt nervous about running out of battery power...I could always plug it into the boat and not worry about low voltage drain because there are three settings on the ice chest to prevent battery damage due to low voltage. The meat and chicken were ice cold, I put the chicken in frozen and after two days it was still a little bit frozen to the point I had to let it thaw a while before we cooked it. I was able to put a dozen eggs, four chicken breasts, 4 t-bones, Two packages of bacon and two sticks of butter and two small cartons of milk and three packages of cheese and 2 pounds of hamburger with a little bit of room to spare but not much.This thing is extremely quiet and very efficient and really does keep things very cold, I bought the insulated jacket to go around it as well. It’s not a huge ice chest it’s only 20 quarts but I don’t have to worry about buying ice and having everything get water longed, it’s a wonderful ice chest and you will not be disappointed. I was not paid for this renew or reimbursed in anyway.

I am leaving my comments below with my testing. I went in to Amazon to request a replacement and that was not an option. So, I am returning the product. The freezer function does NOT keep food frozen. Temp varies from 25 to 40 over a 24 hour period, the thermostat never changed from 25 degrees but the meat and vegetables thawed and barely refroze a couple of times over a 24 hour period. I believe that this is a failure of the unit and dangerous. My TESTING: It arrived in good condition. There was a difference in the unit received and the pictures on amazon. The fuse and setting switch are not on the end. I suspect the fuse is internal. The manual in very poor English and some instructions are unclear and others seem funny in the order of the words used. The cool down was much slower than 15 minutes. After 24 hours the unit did reach it's lowest temp and the compressor cutoff. The display indicated that the unit reached 0F. I will need to find a thermometer to compare the actual temp. But the unit thinks it made it. So, I put in a small ice tray. It makes 40 1/2 inch round "cubes," After 24 hours the outer cells were frozen but the middle rows were completely liquid. There was frost on the coils going half way down the inside of the frig/freezer. It does keep frozen food hard frozen. It should keep beverages cooled when traveling. I will be traveling in 2 weeks and will see how it does longer term. Now at 7 days - sort of a boring explanation of my testing and it is like watching water turn to ice....which is what I did. I ran the unit as a 3 days as freezer 3 days as a frig all on the power cube. I used the MAX setting and ECO during both modes. Today I moved it from the living room at home to my office and allowed it to go to room temp 71F and I used a large DC supply (50 AMPS available) with a marine 12 VDC socket. I put the freezer/frig into ECO and set to max low temp. It did get to a temp of +22F and remained at that level for 3 of 5 hours. I reset to MAX with no temp setting change and it did go to -4F... on the frig. I used a commercial (not medical) touchless thermometer which showed a temp of +8F. I don't know if the compressor has cut off today. It is on as I am about to head home. I increased the temp in the frig 1 degree at a time. When I reached +9F the compressor cut off. I will leave it at the office on my desk for a few days. It has taken 9 hours to freeze 2 out of 6, spaced out, water bottles I put in this morning. The bottles nearest the side walls froze the other are cold with no ice visible. So the compressor is running constantly and it can not get the temp below +8F on MAX setting and +22 on ECO setting. This unit can not reach sub zero in an A/C controlled office environment. The thermostat on the unit falsely shows temps to be in the negative range. I am concerned that this unit may not be working at 100% of how it was described. It should work for me in weekend use. The documentation suggest a high quality German manufactured compressor. I don't know how to tell it that is true. The user manual is poorly translated and is unclear. I added the 5 year extended warranty plan.
