This gadget is going to come in really handy for those of us who get distracted by work (or kids!) and forget to drink warm drinks while they're still warm! Instead of chucking out that horrible cup of cold tea or coffee, you can warm it back up on the USB cup warmer right at your desk! The USB mug warmer plugs into the USB port on the side of your computer or laptop. It heats up to between 80 and 100 degrees celsius so you can warm or reheat drinks or soup inside of a ceramic mug. Use it at home or at your desk at work! The miniature hot plate has an on/off switch on the base, so you don't need to mess around with the cord and USB port every time. It also features a power indicator light so you can instantly tell if the unit is powered on. For safety reasons, USB cup warmers are not recommended for children, but they are an ideal gift for almost every adult person that you know! Your boss, work friend, sister, brother, spouse or parent will love the desktop Product Specifications: For indoor use only Requires a PC or laptop with a USB port (note: an AC power supply must be connected when used with a laptop) The heating temperature of the unit is 80-100 C Sorry, mug not included (for illustration purposes only).
