  1. James G

    My boat has a refrigerator and a tiny freezer that only goes to 26 which is pretty much just ice. I purchased this cooler and run it as a freezer at 7 degrees F. Very quiet and makes less sound than my refrigerator. You would have to stand less than a foot away to hear it. I downloaded the app and use Bluetooth to monitor all functions of my freezer on my phone. So far power consumption is almost zero. I have it on 110 V but underway (offshore) I will use 12V. Very happy with my purchase. I also have several Dometic products aboard and perform flawlessly, worth the extra money for excellence.

  2. Lynette D

    I am in the process of converting my 2014 Honda Odyssey into a camper van. This unit, based upon size, quality, and functionality fits the bill perfectly. Probably a bit pricey, but the quality construction is obvious. Easy to remove this unit from the vehicle and set it on a picnic table when/if desired. Low noise, low power consumption, excellent temperature stability, and the biggest unit that my camper conversion would accommodate. The top of the unit makes a fine workspace or seat within the van.

  3. Tammy W

    Light weight. Fits in the back seat easily. Keeps food frozen for hours on battery. Great for small spaces. We put ours on the boat.

  4. Jordan S

    You can’t go wrong with this little guy. Depending on what you’re doing with it and the size you want. Always keeps your drinks cold and frosty. You can even have ice cream and not worry about melting. You can set this thing to your desired temp and let it do its thing. Great for traveling across country.

  5. Ollie B

    I love just about everything about my cfx 25 its the perfect size for my rogue . Sometimes it gets a little loud, i guess thats the norm. I have the cfx 35 and cfx 75 but their not as loud they are very quiet. For the most part they are the best thing to travel with on the road.

  6. Ryan K

    The Android app makes it easy to track power usage and temperature. I’ve been using the CFX3 25L as a fridge on my sailboat for over a year and wanted a second one to use as a freezer. I was amazed at how efficient this unit is. We keep it at -15°C and it consumes around 2.5 AH/hour.

  7. Lindsey R

    Arrived quickly, well packaged, good instructions. Keeps everything at the temperature setting. Quality is outstanding. I loved the first one I purchased so much I bought another one. Very happy with my purchase.

  8. Wade G

    Listen Truckers! It’s way more efficient to use this a 12V fridge instead of a mini fridge plugged into an inverter. I leave this fridge on for my 10 hour break while running my wabasto heater and my batteries don’t die! This fridge cools my drinks really fast and gets them COLD! I love this fridge it’s expensive but WORTH EVERY PENNY!

  9. Morris C

    I bought this for my pickup truck. I have temp set for 32 degrees. And the battery shut off at 11.9 volts. It shuts down about 5 hrs after driving but keeps things cold for hrs after. Love not having to buy ice every day.

  10. Travis R

    I have had an arb fridge for years but wanted something smaller I could run from a battery all weekend for lake island camping in the boat. I am really impressed. It actually hold alot for the size. I think it is better than my ARB fridge
