Whoever came up with this one is a complete and total genius. The USB-powered Cool-It drink chiller literally works anywhere you can plug a USB cable into, including Xbox consoles, Sony Playstation, Macs, laptops, anything. If your dog had a USB port, it would work there, too. Cool-It keeps your drink chilled to a sweet 45 degrees, and while it can indeed cool off a warm bevvy over time, it’s much better suited to maintaining the ideal drinking temperature of an already-chilled can of . . . whatever. USB Chiller requires at least 1.2 Amps to operate, just so you know. It is USB 1.0 compatible, but mind those amps.
