USB Coffee Mug Warmer with Touch Temperature Control

Keep Your Coffee at the Right Temperature, All Day

This DC 5V USB Coffee Mug Warmer is designed to keep your drink pleasantly warm while you work or study. Built with an aluminum alloy heating plate and tempered glass surface, it offers stable heat conduction and a smooth, easy-to-clean finish. Powered via any 5V/2A USB port, it delivers 8-10W of heating power in a compact, desk-friendly design.

An 8-hour automatic shutoff adds an extra layer of safety for everyday use at home, in the office, or in a dorm room.
