Also, I wonder how long it takes for this device to get a drink cold? Instead of lugging a cooler full of ice and beer to a party, could somebody bring a bunch of cans and this little thing instead? Would it chill your next beverage in the time it takes to drink the first one?
You can buy it for only $19.99, so it's definitely worth finding out. But here's the weird part--it's labeled as a cooler/warmer. From the product description on ThinkGeek.com:
-Chill a can down to 46° F / warm a can up to 149° F
-In-line switch included at no charge to change between warm & chill with LED indicator
-Yellow when cold
-Red when warm
-Capacity: Fits 1 US standard 12 oz. can
Um, what? When has anyone ever wanted to warm up a beverage that comes in a 12 oz. can?
