Is there anything worse than a warm beer on a summer day? I don't think so. However, there are few things better than a really cold beer on a summer day. It's the difference that's tricky. If you're driving somewhere for a picnic or some other outdoor excursion and you want to keep your beverages cold, you'll need a cooler. But a cooler can only keep things cool for so long.

That's why the CarryCool is here. It plugs into your car's cigarette lighter and turns into a portable refrigerator, keeping your food and drinks chilly for as long as you're driving. That way, when you finally arrive at your destination, there will be no question about whether or not you'll be refreshed or repulsed when you pop the top on a brew. — Adam Frucci
