Koolatron W75 Kool Wheeler Cooler 36-Quart

Along with the 110V power adapter, this product was a great buy. We needed to take something like this along with us on a road trip. We ran it for 8 days continuously, moving it from the car to the hotel rooms we were staying in. It was large enough to hold enough food for a family of 5. We did not use the "warm" feature of this device, only the "cold", but I could see the "warm" feature being really nice. It was really nice not having to deal with filling it with ice constantly, nor having to move food from the cooler to a regular fridge and back.

I specifically liked the following things about it:

It is deceptively big. We had a whole gallon of milk (in two 1/2 gallon containers), as well as lunch meat, all sorts of yogurt/pudding containers, and fruits in there.

The wheels: this was key for us, we looked for the biggest cooler we could find that had wheels. There are bigger powered coolers out there, but this is the biggest we could find with wheels. My 6 year old was able to drag a full cooler from the car to the hotel without any issues.

The fan on the side: at first, I thought it would be a mistake to buy something with the fan on the side (rather than on the top), since we wouldn't be able to stack anything next to it. This, however, worked to our advantage when we decided to keep the cooler in the car (rather than in the trunk), we simply stacked things on top of it.

It runs very quietly, even though it was on in our hotel rooms all night, we had no issues sleeping.

The lid does not stay open on its own, which means the kids can't accidentally leave it open (I could see this being a negative for some)

Some cons (none of which were a big deal for me):

The cooler works by drawing warm air from outside, cooling it, then blowing it around inside the cooler. As a result, the slots where the air comes in will collect frost, and after 2 or 3 days, froze solid, which prevented the air from circulating, which increased the temperature inside. Every couple of days, I took everything out, used a hair dryer to melt all the frost (took a few minutes), then put everything back in after running it for a few minutes. The hair dryer is not absolutely necessary, but it does speed things up.

The handle feels "cheap" (e.g. like it might break)

You need to leave some room near the air vent on the side of the device, otherwise you lose air circulation, meaning things on the other side of the cooler get warmer.

It takes a few hours to cool things down, it is not like a fridge. We cooled all of our food initially in a fridge, then transferred it to the cooler.

I really researched which cooler to buy. I read the reviews, thanks to everyone who posted and didn't want to spend a fortune, but was willing to spend a bit to get a good working product. Went with the Koolatron for many reasons and have to say after 11 days on the road running nearly non stop that I made the right choice 100%!

We ran this thing non stop nearly both in hotel rooms and in the car. After 7 days, a bag of ice I had added at home was still frozen solid and it was colder inside cooler than hotel fridge. No joke! I was afraid to put the food in the fridge so just keep them in the cooler and put the drinks in the fridge.

Add a couple ice packs or a bag of ice as it help keep the temp even lower and since our Honda Odyssey Touring plug in the back turns off when engine is off, the ice helps keep the temp down during gas fill ups and bathroom runs without sacrificing coolness.

I noticed no ice or frost build up after 7 days, but chose to turn in off for a short time & dry it out just to be safe. What I did notice was after that when car was turned off somehow we had a bit of water in the bottom and did not dry it out, then the frost built up. I think because the food was out for a couple minutes, persipration developed on the food. I believe if there is perspiration or additional moisture inside, then likely to get frost. Still ran with frost, but I decided to dry it out and defrost to be on the safe side. I also wiped down food before putting back inside. THis time no frost build up.

Bought the adapter plug for using in the hotels and did as other reviewers said. I cooled it down the day before at home without anything inside so it was cold when we started and added only cold food & drink to it. THIS IS VERY IMPORTANT. No moisture produced. Adapter gets hot for sure. Almost scary, but no problems with it.

This was NOT our main cooler, but for our foods like meats, cheeses, milk etc. that needed to stay cold all the time. Stayed as cold as my fridge at home if not colder keeping ice frozen even in outdoor temps up to 100 degrees while engine was running!

We had a standard cooler with ice for drinks that was used allowing the Coolatron to protect vital foods. Highly recommend this cooler and adapter, but Amazon needs to fix the packaging as we did have minor damage and could have easily been destroying or severely damaged in shipping. Do not order last minute. We did and had one wheel with minor damage and the plastic restrainer for the lid was broken. No time to exchange, but works fine without.

Right out of the box the wheel on this cooler fell off. The wheels and handle are very cheaply made. I needed it so I used the cooler anyway. Once cold, it kept drinks very cold. I would not recommend buying the one with wheels.

Koolatron was received as expected. Although it appeared to be cheaply made, the size and appearance was as expected.

I would have liked it but it only worked for a week before it stopped cooling or heating. Cost too much to use it with ice.

I have only run it in the house overnight and a few hours in the truck but so far it works like a charm and really keeps things cold. I hope it is reliable over time because it's great so far.
