This works great. I have plugged into outlet and it doesn’t take long to get cold maybe 45 mins to an hour depending on how cold you want it. Fits a lot of stuff. A little heavy but expected since it is like a mini fridge lol but not too heavy for me to carry alone. I haven’t tried it plugged into my car yet. Direcrions are easy as to how to use and I feel a great product it also looks good once it is at a temp it holds that temp no problem

We purchased this unit as an upgrade to our existing refrigerator only unit. We’ve done several tests and surprisingly it chills super fast, within 15 minutes. I’ve taken it to the 0° mark and was able to transport frozen ice cream with no problem. We tested it full of food at the 28° mark and everything Was kept equally cold to our home refrigerator. This is a great option for camping and I am so excited to not need any more ice. We’ve also tested it on our small gold labs solar power box. We would do the initial cooling on max mode, using the house plug or car charger and once out of the car, use the eco-mode with our solar box, which gave us at least six hours at the 28° mark. We also have a portable solar panel Which you can hook up in sync and allow it to run for a longer period of time. Our main concern was overnight cooling which we determined that with a six hour available charge on our solar box. It would hold the 28° temperature through the night from 11 PM till 5 AM. We’ve done several tests to see how long the freezer would remain cold without it being plugged in and that is two hours. Ultimately with no sun we can eight hours total cooling time. Then when you wake up in the morning, you plug it back into the car or the solar panel using the sun and continue on. I highly recommend this unit and I am very impressed with its compact size, but yet has more than enough room for all of our items that we typically take camping. the whites it needs to run our half of what our old little refrigerator took when on eco-mode. The eco-mode is super quiet, and I gotta say that the max mode is also quiet as I can hardly hear it so the noise level is exceptional. I would only recommend using the max mode if plugged into a car or house, since that would drain too much from our solar box and cut our call time and a half , the unit does weigh a little bit without food but it’s well worth it to avoid the bags of ice and melted water.

I think that for what you are paying, this is a great fridge (AJ40). I have been testing it over the summer months in my car with a portable power station to keep it running while the car is parked and will say it does a fine job. The big test will be next year when I [hopefully] go on a cross country trip to some national parks. I will make one mention that kept me from giving 5 stars. My fridge seemed unusually loud (~50-60 dB) when the compressor was running. I previously did not have any experience with such 12V refrigerators so I reached out to customer service to ask if this was normal. Setpower customer service was quite responsive and was clearly trying to be helpful. I sent several short video clips demonstrating the issue. Customer service agreed something was not right, but they passed things on to R&D for another opinion. R&D said this was normal operation. Support offered me a 5% refund for my trouble, and things ended there. Well, the sound level still bothered me, so I ordered a second fridge, and my suspicions were correct. The compressor of the second fridge (same exact model) ran at ~40 dB - significantly quieter. I returned the louder fridge. Again, for the price, I think it's a great value. Folk should be aware of the noise level as these can truly run quietly. Customer service was great but came up a bit short in that they didn't offer to replace the fridge on their own. But really for the price you can't go wrong.

Why did you pick this product vs others?: This fridge/freezer is better than I ever expected. I've used this as a beer cooler mostly on my live-aboard sailboat, as an overflow from my regular refrigerator, it keeps my beer at a perfect 34 degrees. It has a power adapter that plugs into either AC or DC cigarette charger. This is my second summer using it, and it is perfect. I am thinking about getting a second one as a dedicated freezer. It is highly recommended.

The fridge easily chilled down to 35 degrees in 45 minutes with a half-full load of room-temperature items. However, the freezer could not chill below 10 degrees after five hours in a 70-degree home. I did not install the two handles to maintain a more compact size. I improvised the handles using straps, as shown in the photos. This makes it easier to carry and retains its compact size. The manufacturer could've likely reduced costs and size by eliminating the handles and using straps. Overall, this is an excellent fridge if you do not need a freezer at zero degrees.

The Setpower cooler/refrigerator is amazing and exactly what we needed! We had a smaller cooler prior to purchasing this one, a little hesitant to buy because of the price but we are glad we did! The size is fantastic for camping and for use as a back up/extra for our 5th Wheel Trailer. We have used this for about 6 months over the past year and it is still working well. The DC cable is the old version and is not the greatest, but SetPower customer service is working with us to replace it! Highly recommended to anyone needing a portable refrigerator for home or on the go!

So far I'm impressed. Handles a very heavy duty. It cooled down very quickly and isn't noisy whatsoever. Left yesterday. 700 miles and it worked flawlessly. Held 37 degrees the whole day. Totally impressed. 12v or 110 is awesome. No more bags of ice or wet food.
