With the USB Mini Fridge, you can keep a cool beverage ready to drink at all times! It holds a single 12 ounce can, which is illuminated from the blue LED inside the fridge. A built-in cooling plate quickly drops to its lowest operating temperature within five minutes after being plugged in. The USB Mini Fridge can be used in your cubicle, home office, bedroom or garage! It works with any computer operating system and does not require batteries. Simply plug the USB port in, insert your canned drink and enjoy!
