Hearthwear Steaming Mug - USB Desk Mug Warmer Coaster
Keep your favorite cup at the perfect sip temperature without taking up counter space. This compact USB mug warmer sits neatly under your travel mug, tea cup, or coffee tumbler and holds a steady, comforting heat through long mornings, late-night reading sessions, and desk stretches — no kettle trips, no lukewarm surprises.
A gentle, auto-shutoff thermostat takes care of warmth and peace of mind, and the slim disc tucks away in a drawer when the season turns. Plug it into any USB port on your nightstand or desk and let the next cup be the last warm one you'll need all morning.
Includes two cord lengths so it fits your setup — the black variant is a standard cable and the "black add 1m cable" gives you an extra meter of reach for a farther outlet.
A Hearthwear pick — curated to feel like home, wherever you are.
