    GreatAmazing fridge/freezer. Bought this for my husband who was heading off to do the North Coast 500, he is very impressed with it.

    Frigo x il furgo🚐Dopo aver preso in considerazione molti frigo in molte versioni x il mio furgone, su consiglio dell’amico meccanico nonché appassionato di Vw mi decido ad acquistare questo modello testandolo solo brevemente aspettando l’estate x metterlo sotto stress.PRO:Prezzo competitivo rispetto ai concorrenti.Buona capacità di stock.Robusto a vedersi.Buona insolazione del coperchioCONTRO:Nessun controllo digitale.Maniglie laterali fissa e non a scomparsa.Le leve di chiusura del coperchio a vedere poco di qualità,sembrano fragili. TEST: A 230V 1h da +24°C a -5°C, set del frigo al max.Dopo 1/2 h a frigo spento e chiuso -5°C, 1h 0°C, 2h +8°C.

    Muy buena nevera-congelador.Este verano nos íbamos a Alemania de vacaciones con la autocaravana y como sabéis los que tenéis una autocaravana los frigorífico trivalentes enfrían poco en verano y congelan lo justo y encima el conge lar es pequeño.Así que me decidí por una nevera congelador con compresor y no puedo estar más contento.La puedes usar a corriente y a 12v que es como yo la he usado. Te trae los dos cables y un adaptador del enchufe para que pongas el que mejor te convenga.La nevera es de 40 litros suficiente para mis necesidades.No tiene ningún reloj,pantalla digital que nos indique la temperatura a la que está.Solo tiene una ruleta que del 1 al 5 y en función del número que le pongas te enfria o congela.Del 1 al 2 hace de frigorífico solo enfría y a partir del 3 al 5 congela hace de congelador.Yo he comprobado que en el 5 la temperatura a la que estaba era de -22°.Yo lo he utilizado de congelador,hacia comida en casa y la envasaba al vacío y luego al congelador y te entra muchísima comida ya que el compresor está separado de lo que es la caja donde dejas los alimentos.Lo único que podrían mejorar son los cierres los veo un poco débiles pero aún así cierra herméticamente.Apenas hace ruido el compresor y si quieres le puedes comprar una funda térmica para protegerla y también para que el calor exterior no le afecte tanto y tenga que entrar el compresor menos veces y así consuma menos batería que por cierto tampoco consume mucho.Yo estoy encantado la mejor compra que he podido hacer para la autocaravana.

    Unbrauchbar durch TransportschadenDie Kühlbox geht leider zurück, Verschlüsse sind gebrochen, Box dadurch nicht brauchbar, da sich der Deckel nicht verschliessen lässt.Sehr filigrane Verschluss-Halterungen, die offensichtlich beim Transport beschädigt wurden.Schade

    ExcellentThis is my second Engel, and is just as good as the last one. Good sturdy construction and the low power demand which makes them ideal for 12-volt applications. A standard car battery in good condition can easily run this fridge for 24 hrs and still start the car. I would have liked to see metal handles instead of the plastic ones, or some alternative means of easily securing the unit for off-road situations. Additionally, I think a digital temp display would also be useful. However, I did purchase the Engel wireless digital temperature gauge which can be remotely mounted

    My biggest problem if you could call it one is that I too easily freeze thingsI’ve been running my MR040 continuously since March 2015, half the year in my 4×4 and half in the house, and it’s been flawless. I rarely want things frozen inside, though it’s seemingly effortless for it to do so, and so I run the control between 1 and 2 (out of 5). My biggest problem if you could call it one is that I too easily freeze things, even on a 90+ degree beach. I would like it to have electronic controls but I see where Engel prizes durability and longevity over all else – and that’s ultimately why I bought an Engel. I know folks who have them from the 70’s having never broken down. Nice.UPDATE: Hi folks! Three years later and the fridge is dead…… just kidding. Its worked flawlessly since the day I first plugged it in back in early 2015. Year round. It”s sitting next to me in my truck, on a beach, and keeping a load of food and drinks ice cold. With the knob always pointed at the green light, which I believe is about 1-1/2 out of the 5.Its in like new condition and I even got a top basket for it, to hold the little stuff.I guess I’ll report back in about 5-7 years next, though I don’t think things will have changed.

    The COMPRESSOR is THE reason for buying ENGELThe 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

    BEWARE: Questionable quality components/design, poor customer service, poor warrantyI can say that the fridge/freezer part works.I can also say that;1) it is hard to find out how to submit a warranty claim2) when you do figure out how to contact them, customer service is slow (5 days to even get a response)3) they do not back up their product well4) some of the components are made of very poor quality materials and have weak designs (look at the photos, decide for yourself)Below is their response to my receiving a damaged unit with a broken plastic lid latch (not surprising as they are made with brittle plastic with thin parts prone to breaking; shocking when you realize these are supposed to be rugged and used heavily):My warranty claim ” I just received the unit and was shocked to realized that one of the lid latches is already broken. Please send me two new latches, I will attach the one and keep the other as a back up as they are clearly ridiculously fragile.”Their warranty response:”I’m sorry you had an issue with your latch breaking. The latches are not covered under warranty. You can place a phone order by calling customer service”By the time I got the reply, I had used the cooler already so did not feel it was right to return it (I guess I can always use a bungee cord to keep it closed); but if you think a product in this price range should:- arrive undamaged,- have good quality customer service and- that the parts should all be made to last then……….this it NOT the company for you to buy from.If the company corrects its breach of basic legal responsibility to the consumer and quality control, I will update the review.
