Document: We are very surprise not only keep cool but  cold . It is large I Recommend it. The price is good
as a otr truck driver there are alot of unhealthy food choices... but its important to eat healthy...lots of fresh veggies and fruits, yogurts and dont forget water...this cooler is awesome...it works great and when its a hot day...i through a bag of frozen veggies...and it keeps everything cool...
This is the second one I have bought. I am an over the road truck driver. And this works great to keep my meals cold. It saves on having to buy while out on the road. I have even used for weekend trips with the family. I would highly recommend this cooler for Rig drivers, going away for a weekend, just about anything.
As of the date of this review, Amazon still has a weird product description shown for this item. However, we did receive the right product, which is the Coleman 40-Quart PowerChill Thermoelectric Cooler with adapters for plugging into either DC or AC power sources. We use the cooler to keep beverages cold for short periods of time, though it probably works nicely in many other situations, too.
The Coleman PowerChill Cooler was purchased for traveling. I found the build quality acceptable though not particularly impressive. Hard plastic and poorly designed joints. Functionally I needed a cooler to keep film cold during road trips. The insulation in the cooler was minimal and it would quickly drop the internal temperature while in a hot car. No power, no cooling, therefore not a keeper. Did not meet my needs.
it will freeze items if its cold outside. cant beat the buy, comes with adapter for wall plug and ice cold.
Works great for keeping drinks cold. We camp a lot but will only use it when there are power hookups. It took a day or two to get the drinks really cold, and the items next to the fan thingy were the coldest. So we will pre-chill our drinks before putting them in this. I wouldnt trust a car battery to run it without killing the car though! So, if you have hookups, it is definately worth it.
Warning: do not buy this item because the cord burned within 5 hrs of using it. You have to wait 2 months for a replacement cord because company has a shortage.
This unit does exactly what I hoped it would do. My reason for purchasing was to have a place to put refrigerated items while shopping more than an hour from home. If I am driving that distance I would like to take advantage of other stores in the area and even though I have used a cold bag in the past it is rarely successful enough to allow me any flexibility. Not having to use ice allows more room to put refrigerated items. Even frozen foods retain their coldness.
This guy works great and has been used on every drive vacation and lake trip we have taken this year. It is great being able to avoid melted ice messes.
Answer: no
