Fridge/Freezer Anyone?

I bought a couple of these back in October 2020 because they would come in handy on the boat. Bought them from Bangood which is a Chinese Amazon style store. I could not believe the price as they were only $155 at the time and one pays a lot more just for a high end cooler nowadays. The unit has a real compressor, runs easily down to -20c or can simply be used as a fridge if one desires. Very, very quiet by the way, almost completely silent. Tried dropping it into the Y just for fun. Holy *sugar*, it fits no problem! Plugged it into the 12v socket back there to see what happens. Runs fine and the circuit does not trip. I assume it will work fine as long as the car is running such as a road trip and once at destination simply bring it indoors and plug into 110v as it runs off both, adapters are included. Not huge but will hold 9 bottles of wine. :D Popsicles from the trunk?

Need to experiment a little more, right now it is in the car with temp set to -20. Another cool thing is there is an app that can control/monitor the unit from your phone. looking at it right now from my computer in my house and I see it has dropped from +15C to -8C in about 10 mins or less. 12v circuit so far has stayed alive but not sure for how long of if the main battery replenishes the 12v side if it gets low. Takes less than 15 minutes to go from room temp to -20C.

Pretty cool and may come in handy for several.

The brand on this one is iMars however the app says Alpicool who do make one which looks identical so I must assume they are the same.

There is not much heat at all. After having the unit all night long at -20C in my home I could feel no heat whatsoever where the ventilation holes around the unit are. Not saying there is no heat produced however it is very minimal. I suspect the rear hatch has such a poor seal or lack there of that this is not an issue. The frunk on the other hand on a hot summer day may prove to be a challenge though. Ventilation could easily be added to the frunk by means of a small 12v computer fan. Lots of room if you pull out the frunk tub.

Thread bump. Any new learnings from this one? I was thinking about long trips in the summer with a powered cooler (no need for ice, wheel it in and out of car without having to take stuff out, etc.). I'd be worried too about heat dissipation if seated in the trunk or trunk wells. FYI, Costco is selling something similar that's a little bigger (https://www.costco.com/massimo-cx30-12v-portable-e-kooler.product.100566474.html), not sure if it would fit the same way....

Agreed about the heat. You can't fight thermodynamics.

However: If you pre-cool the things you put in it, then the only heat it has to lift is the leakage through the insulation. And based on the photos in the original post, it looks quite well sealed. So... maybe? I also would love to see a test of running it hard in the sub-trunk with the lid on and stuff above. Maybe put in a liter of water, set it to -10, and see how warm the sub-trunk gets while trying to cool and freeze a kg of water.

Hmm, if that's still the price, I might just buy a couple thermal data loggers and try it myself.

UPDATE

The 12v plug in the back of the Y as we know shuts off when one leaves the car so I was looking for a solution to the issue. The on board 12v battery is so small it would kill it in no time with a direct connection plus the newer units with the lithium battery create an issue as once again just do not have the capacity to keep a fridge running for ant reasonable amount of time.

A battery lithium battery pack solves all these issues except one obviously need to recharge the unit which can be done on the 12v electrical socket of the car while driving although that would be rather long as the battery capacity is 1100wh. Best bet is to charge it up at home on 110v.

The battery pack fits nicely into either side compartment or can be inside the sub trunk which works very well also.

What brand or model battery is that?

try turning on sentry mode to keep the rear 12V running, as that is how I get around that issue. Also I believe the car should auto top up the 12V battery when it is low.
