EUHOMY 12 Volt Refrigerator, 38QT(35L) Electric Cooler, 12V Fridge APP Control, 12V Cooler -4℉~68℉, Portable Freezer 12/24V DC 110-240V AC for Camping, Travel, Truck, Home

Just got the Euhomy Car Refrigerator Model CF-55. (June 2021 in North Carolina, Outside temp 72-85F)It arrived 2 days earlier than expected. The Fedex people unfortunately left it on its side, so I had to take it out and set it upright for about 24 hours before using. Started up fine.TESTING IN MY LIVING ROOM (AC set to 78F). Set the Euhomy Frig to 34 degrees F to cool down drinks for a party. Loaded it up with soda and water. After 1 hour, the unit's internal temp was nice and cold at 34F, but it still took another another hour or so for the initially room temperature cans and bottles to be thoroughly chilly. After that, the drinks are perfectly cold for a hot day (thumbs up from the kids!). It's much more efficient when the frig is full of cold drinks/food. Pretty solid performance overall.POWER. In the above scenario, I tested it using AC (from the wall) and DC (using an external battery's DC port). On AC, it can draw 60 watts/hr at first when starting at room temp. After it reached its target temperature, the compressor cycles off and on. With DC, when the compressor is on, it is then around 40 watts/hr to maintain (in ECO mode). I left it running overnight connected to my battery via the DC port, and it was a negligible draw, less than 100 watts total (But the already cold drinks filling the unit helped it stay cool efficiently).DETAILED APP INSTRUCTIONS. It's not hard but might be confusing at first.Here are detailed steps to INSTALL and USE...1. Plug in the Euhomy frig (the LCD screen on unit should have a Bluetooth symbol at upper left)2. Download the Alpicool "Car Fridge Freezer" (I just searched iOS store for "Alpicool" to see its apps)3. Open the "Car Fridge Freezer" app4. On the App: Click on "Start Scanning" (button near bottom). Takes about 20 seconds...5. On the App: Double-click on the rectangular button that appears. It says "A1-4XXXXXXXXXX"6. Within 5 seconds, on the Frig LCD screen, press the SETTINGS button (looks like a gear) once.7. The App should now switch to its main operating screen-You can see INFO (top half of screen): Current internal unit temp, Target temp, Voltage draw-Using the POWER Icon in upper right area, you can Turn your frig ON or OFF-You can set the target temperature by using the horizontal SLIDER in the middle-Using Bottom Buttons: You can also set to use ECO mode (uses less power, but is slower to reach target temp)-You can also set the LOCK button (this locks the unit's LCD screen from being pressed)-You can set to use Celsius or Fahrenheit degrees-You can click the UNPAIR button to disconnect your smartphone's connection to the frig bluetooth-You can set the cutoff voltage related to your car battery draw (High, Medium, or Low)Overall, I really like this unit and its app.PROS• It gets the temperature cold pretty fast and stays icy cold.• It can hold 55L (or 58 quarts) of capacity (which is pretty huge)• It seems very efficient when drawing off DC on a portable battery or car battery. It sips power overnight.• The app is simple but useful (especially if one is driving and wants to check on the unit in the back)• The price is awesome (low $300's) when compared to big name units ($600+)CONS• It can get a little heavy (30 pounds +) to carry around if you are camping. I just bought a cheap $10 wheeled platform from Harbor Freight to use with this when it's fully loaded.• It is bulkier than a normal non-powered cooler, but if you're like me, I bought it for its extra large capacity, so I can't complain about it. I have to remember to keep the air vents clear around the unit when it is in the car, so that it won't overheat.• The app works, but I really wish they included instructions on it installation and use in the manual. The manual has no details at all. Had to google search for it (That's why I added detailed instructions to my review)Can't say anything about its sturdiness at this point, but its looks and feels pretty solid. I will update if there are any problems in its long-term performance.

We use this cooler camping our. Obviously, it needs to be protected from rain and or water. It started cooling when we plugged in. Inside half a hour it cooled to 18 degrees F. I like the small freezer. Also, I like the baskets in the cooler section. This will save money in food thrown out. As of now it has worked for 18 hours. I will rate this as a 5 star. I will also report more later.It is now day 2 This mnorning I put 11 liters of water. I set the temp at -4 degrees F and let it run now for 13 hours. The water is now about 1/2 frozen. This tell me that this freezer is okay for keeping things cool. But, it may not be good from a standing start. I would cool anything I want ahead of time before I use this cooler. Also yeaterday I placed two gallons of cool drinks in the cooler last night and 2 ice trays in the 'freezing compartment. I had sonfigured the cooler to what I thought was reasonable. The cooler would cycle between the interior temperature (41) degrees F then down to 22 the compressor would then turn off. The temp display would them raise slowly back to 41 where the compressor would restare. It cycled this way several times before I set it back to the Factory settings. When I checked the Ice trays they had thawed about 1/2. The cool drinks seemed to still be cool enough to drink. Where it would cool to a set temperature and hold. I used the factory settings in starting my test this morning. So, I would suggest the Factory settings are more optimal. Don't worry too much about things freezing. And, that the 'freezing compartment does not seem to become any colder than the larger compartment. It has run for 13 hours straignt and is holding a -1 F temp., so I would keep this cooler at a 5 stars.Follow-up: Once the water was frozen, I placed a hard frozen liter in the 'small' well. I thought that this well would be cooler than the large. I found that this is not the case. I set the temp. to 20 degreesF ( I had been told this was a good temp. for Ice-cream). Over the course of 2 days the water containers in the large well remained frozen. The measured temp. was 28 F. But, the small well thawed. The measured temp 40 F At this time, the liter has a thin piece of ice in the center and the rest of the water is thawed. The temp. given by the cooler display is 20. So, the instruction manual does not share this. If I need to keep food thawed and not frozen, the small well is the place. Regards
