Koolatron 12V Electric Cooler/Warmer 34L (36 qt), Two-Way Design, Gray

Keeps things pretty cool, though i wouldn't trust milk in it. I love the option of using it to keep things warm should i need to bring precooked food somewhere. My goal was to use it as a mini fridge so i had to buy an adapter for the car plug it came with, but it so far, after a month of use, does the job. Like others mentionned: how cool it get depends on how warm it is outside of it, so plan around that before putting in stuff that goes bad quickly, but it keeps my hummus, fruits, and iced tea cool enough.

we really enjoy our Koolatron cooler. It has been put to use daily along with our smaller Motor home fridge. We make less grocery trips, which saves us valuable time. The cooler has helped us through Mid30 temps. Haven't esed it to keep any foods warm, but can imagine that the cooler will function equally as well for keeping dinners warm.
