Mug warmers are one of the most ingenious products ever made. Electric mug warmers are just so much better since they harness to power of man-made electricity to keep our beverages warm. However, there’s a new type of mug warmer available: one that plugs into your computer or laptop’s USB port. This means you can enjoy a warm cup of joe or cocoa while binge-watching your favorite TV shows for the hundredth time without needing to get up and reheat your drink in the microwave. Don’t expect too much heat from this device; it’s meant to keep your mug warm, not burn evidence.
