ENGELMR040 40 Quart Portable Top Opening 12/24V DC - 110/120V AC Fridge-Freezer

We have this MR40 in our travel van and love it! Durable and quiet (it’s under the bed). It sips power, even in hot Southern summers. It saved us after a hurricane when power was out at the house. We simply transferred food to the Engel, and went about our food lives as always. We bought this during Covid times, when supply was short. It was the only one we could find. I’m glad we found it. It’s been great!

The Engel compressor has just one moving part. You really need to enter a search term "Engelcoolers" to fully understand & appreciate the design engineering of the compressor. Scroll to the bottom of the page where you see a description & drawing showing the compressors design & the reason 45 watts is the current draw when running.VAN BATTERY - All I have to power the freezer is the battery in my van, the same battery I rely on to start my van. It is sufficient for 7 days/night to power the freezer 24/7. Nothing else is needed, thanks to the efficient, low-power requirements of the Freezer which is wired directly to the van's battery.I used a magnifying glass to inspect the prongs on the plugs as well as inspecting the female recepticles for scratches. There was NO EVIDENCE that the plugs had ever been used/inserted into anything.I added lock washers to the screws when attaching handles to the freezer. Several screws holding latches & hinges were loose so I tightened them with my phillips head screwdriver.AC & DC POWER CORDS - Do yourself a favor add grommets to a 6 mil ziplok baggie & attach the baggie to the freezer handle away from the compressor. Put the power cords in the baggie. That way you always have your power cords with the Freezer & don't have to go looking for them.FREEZER CONTROL SETTINGS - (1-5 with 5 being coldest) @#3 = 15º; @#4 = 5º. Atmospheric Temperature = 74º inside my apt.CAPACITY - 40 qt which is the equivalent of = 1.33 cubic feet. I preferred this model over the slightly larger 45 qt freezer because of the way the lid opens.I ran my fingers around the lid seal & felt no cold escaping even though the latches seem loose. I also painted a white line on the Temperature Control which help me see the setting in subdued lighting.SPARE FUSES - When you buy the Freezer, be sure to also buy a spare THERMAL FUSE which costs $10.00 for the 12v power cord. I also went to the auto parts store & bought a spare 10 amp fuse for the Freezer. Tape the Spare fuses to the Freezer for that just in case moment.This freezer will be inside my Ford E250 insulated Cargo Van. For now, I'll have it powered by Van's battery when I'm out on a trip, camping or otherwise. I stock the freezer with freezer ziplok baggies containing cooked & prepared portions of omelettes, beef stroganoff, beef stew, thin cut pork chops, thin cut raw rib eye steaks, & a small Tupperware container of ice cubes. The ice cubes are my "acid" test of checking to be sure the freezer is keeping my food frozen 24/7. When I want to eat I take the frozen ziplok baggie out of the freezer put it in a pot of boiling water & in short order have a 5-star delectable, nutritional home-cooked meal. Between the van & this freezer, I have NO NEED for lodgings or restaurants during my trips.SHIPPING/SUPPLIER - I bought mine from BIG FROG MOUNTAIN. I place my order Monday morning. It was delivered by FedEx Friday p.m. It doesn't get any better than that.NOTE: There is no reminder to REGISTER your unit with Engel that came with my Freezer. So I simply went online to ENGEL's website, looked on the bottom of the page & found where I was able to successfully REGISTER my unit with Engel. This Freezer comes with a 2-year warranty, beginning from the date of purchase. Competitors offer a 1-year warranty on their compressors

I did a lot of online research on these refrigerator/freezers. I choose the Engel due to reliability. Basically the decision came down to the Engel and ARB. I like the idea of the single moving part Engel swing compressor. Engel wins!Out of box unpack audit was a little disappointing. The unit seems to be packaged well however there are no cursory unboxing directions.If you open it from the top and try to dig your hands in and grab the cooler there is nothing to grab onto because you have to attach the handles. There are tight fitting recesses for each corner in the bottom of the box. Pulling the cooler up, the recessed cutouts grab the rubber isolator feet and pulls them off the cooler. Pulls them right over the screws and washers holding them on. So now you gotta figure how to screw them back on without flipping over the cooler. Once I got the rubber isolation legs back on, I noticed the lid was loose. The hinges and latches were loose, not screwed in all the way, so I tightened them up. Not a good first impression.I set the unit up and immediately plugged it in to AC current to test it out. I put a few room temp items in along with a wireless room thermometer. It quickly (35 minutes) went from 85° ambient to 37° for refrigeration mode. I left it there for several hours then turned the freezer setting on. It went to zero within an hour. It froze some water containers quickly.I purchased a 12 volt 55ah deep cycle AGM battery as a spare power source and backup to the AC and my vehicle battery. Both AC and DC can be plugged in at the same time. The unit defaults to AC power. So if AC power fails it will switch automatically to DC, then back to AC when restored so you loose no cooling.I tested the unit just on the AGM battery. From full charge, 12.7 volts, I ran it for 48 hours with a decent load of items in it at refrigeration temperature 37°. Ambient temp was roughly 80° during the day and 60° at night. I opened and closed the unit ten times per 24 hour period during this time to simulate real world usage. At the end of the 48 hours the battery voltage was at 12.2 volts. So in 48 hours it ran down the battery .5 volts. Not bad.I then put the unit in the back seat of my truck for one week on refrigeration mode 37°. It held temperature fine even though at times it was in the sun. When parked I made sure to keep it away from the sun, however it was in a black truck and it was 85° outside. The truck battery was always at over 12.4 volts in the morning with the Engel and a bunch of other electronics responsible for the drain from 12.7 volts full charge.My usage for this is refrigerator is primarily camping in Baja, many times in remote areas with rough roads, sporadic AC power (if any) and warm days.My testing so far has worked out favorably. The main concerns were reliability and low power consumption. I think the Engel satisfies those concerns.
