Tired of always having a lukewarm cup of coffee by the time you get to work? Wouldn't it be nice to enjoy your coffee at your own pace, rather than chugging it down before it gets too cold? We've got just the thing for you! This USB-powered coffee mug will keep your coffee (or anything else you decide to put in it) at a nice, warm temperature. It runs off a built-in rechargable lithium battery, and has a remaining battery indicator on the side to let you know when you need to plug it into the closest USB port. This crafty coffee container even has an automatic mixing function to take the hassle out of adding the sugar and cream, as well as built-in magnets to magnetize your coffee (supposedly this is better for your health). If you're a fan of warm beverages, this is a must-have!
