On occasion, ice and insulation aren"t enough. Maybe you don"t want to keep making that trip to the gas station for another bag of crushed ice. In that case, harness the voltage of your vehicle to chill your beverages. Simply plug into your car"s 12V adapter and chill your drinks to 35 degrees below ambient air (unless you"re in the Arctic, where hot cocoa seems a better choice anyway). Convection cooling cools everything quickly and evenly, including 2-liter bottles stored upright. Handle is durable, and can prop open lid. Put this technological innovation behind or between car seats for a cold drink on the go.
