"Cooler" is not cold,
This review is from: Koolatron 14-Quart Soft-Sided Electric Travel Cooler, Dark Grey (Lawn & Patio)
The cooler won't get anything cold - mine only went down to 50 (in a 70 degree room) and it took many hoursto get there with anything in it. (It was blowing 46 degree air after 2 hours). And it warms up quickly - 14 degrees in only an hour and 1/2.
Add to that a continuous whir noise, so you don't want to bring it into your motel room and leave it plugged it and the battery load which occurs if you leave it in the car overnight, this is a limited use device (in my humble opinion).

We've tried several 'electric' coolers and none of the work as advertised. The way to keep things cold is to use them in combination with the larger ice packs. Then the B&D cooler we have will keep items very cold (as long as they started out cold) for 12-16 hours. My husband drives a truck and 14 hours is a regular shift. He often brings home unused drinks and they're still cold coming out of the cooler. Without ice packs, you're lucky to get 4 hours.

This is rather typical for these. Thanks for the heads up though. I have as of yet to see a portable that uses an actual gas exchanger - most of these are using a peltier effect thermo-electric element. You can actually get considerable cooling with a peltier mechanism, but you still need somewhere to vent the 'hot' side of the element. (peltier is a property exhibited by most metals that when you run a current through them, one end gets cooler, the other hotter - of course, like most behaviors it's more pronounced in some materials than others)
These are generally meant as a cooling 'assist' than anything else. I'm looking for something I can throw small game in if I should ever want to go hunting before work. But I would plan on bringing some ice packs along with me and just use the 12v to extend the life of the ice packs.

I had one of the original kooltrons in the early 80's and it did keep things cool and would also warm stuff up. I kept it until the plastic started to self distruct. In many ways I now wish I kept it or at least the electronics.
Looking now for a new one, One thing about these electronic ones is they state that the units can only cool down to a point below ambit temperature. Tho I have seen ice on the heat exchanger fins on the inside.
They are what they are, and I had no problem with my old unit back in the day..33 or so years ago.
