Have you ever made a cup of coffee or tea and sat down at your laptop to get some work done? Next thing you know, an hour has passed and your beverage is annoyingly lukewarm. Well, now you can keep your hot beverages hot longer with this nifty USB heated travel mug.

This mug, costing just $8.97 on Amazon, comes with both a USB and a car adapter. The USB adapter is meant to keep hot beverages hot for longer periods of time, not to heat things up; computers usually can’t transfer that much voltage through a USB port. According to reviews, the car adapter, however, is pretty good at re-heating a beverage that has lost some of its initial burn.

Perfect for busy people on the go! What do you thinK?
