The only thing better than cookies and milk is cookies and coffee, and I’m happy to pair just about any cookie out there with a cup of freshly brewed java. This Hot Cookie USB Mug Warmer was clearly designed by someone who feels exactly the same way. This cookie isn’t one that you can actually eat, though it really does pair well with a cup of coffee. This is a cup warmer that is powered by any USB port and will keep your drink at a temperature of up to 140F for hours at a time (though you’ll probably need at least one or two more cups if you’re going to be working for several hours!). Any ceramic cup can be placed on top of the cookie and your beverage – wether it is tea, coffee or a mug of hot chocolate – will gently heat as it sits. I recommend starting out with a warm beverage because the hot pad is better for maintaining temperature than it is for taking the chill off if your drink is stone-cold. The cookie is about 4-inches in diameter, which should be wide enough to accomodate the vast majority of coffee mugs. The cookie also has an On/Off switch, so you don’t need to plug and unplug it throughout the day.
