Question: Does it include DC adapter ?
Document: The item works as described.The fan is quiet and with the vehicle running I can't hear it.When not in the vehicle, I use the cooler with the Koolatron Multi-Purpose Adapter 110AC to 12 Volts DC ( Model AC-15)
We used this cooler on a recent vacation. It was nice to have cold drinks readily available while driving. We also bought the adapter so we could plug it in when we stopped for the night. It is very light weight and convenient.
We bought an adapter to keep it plugged in when we were in hotel rooms without refrigerators.For the price, it wasn't too bad. It was big enough to be useful, but it had a low-enough profile that it sat on the floor in the car behind the driver's seat.
This arrived yesterday and I did a "dry run" with it. First off, I had no clue, for some odd reason, that it was also a heated device. So, imagine my surprise during the first test when the inside was getting hot, lol. I then read further and found that if one flips it to the blue side, it cools, the red side is for heat. I got an adapter since I will not be using it in a vehicle.
I purchased this item because I needed to keep my toddler's milk cold while on camping trips this summer. It works great! I recommend putting food in that is already cold because it does take time to get to a cold temperature. Although, when putting water bottles in after it's been on for a while, the water cools quickly.In order to take fridge out of your car, I suggest buying the adapter so you can plug it into a wall.It is a good size for my needs.
My Gator Ade was actually too cold. I also left said drink out and it got warm, of course. I then put it back in the cooler and it was super cold within about an hour or a bit more. I hope this helps others. Oh, I almost forgot to mention something. Since my van is a 1997 and the cig lighter hasn't worked in years, I bought that adapter deal that turns it into an electric device. That worked fine.
very poor quality. does not keep cool anything.waste of money. I wish I could return this stupidproduct. first time bought a bad product from amazon.
You can also buy one of these on Amazon at the same time you purchase this Koolatron.Hope this review was helpful!
Works very well, kept the drinks cold without the hassle of dealing with ice. Doesn't take up much room, very quiet in operation. Highly recommended.
While it was cheaper than some of it's competitors, it was a little pricey, but I would definitely don't regret it after seeing how well it performs.UPDATE 3/14 - we take this with us on every car trip we take, just to keep water cold and sandwiches if it's a long day trip. Some reviewers commented that it ran the battery down when the car was turned off. However, when we turn off the engine, the unit shuts down. We have not experienced that problem.
Answer: yes
