“A mug warmer works just like a hot plate in a drip coffee maker,” says Calatrello. “It does a decent job of keeping your coffee hot, so long as the mug is placed on the warmer while the coffee is still hot.” Calatrello advises that a mug warmer shouldn't be used to heat already-cooled coffee.

Functionally, a mug warmer is a tiny hot plate that sits on your desk and heats the bottom of your cup to keep the liquid inside hot. A good mug warmer will keep your drink warm without exacerbating unpleasant flavors via scorching.
