This USB-powered smart mug warmer keeps coffee, tea, milk, or hot chocolate at a steady drinking temperature for longer. It offers 3 preset heat levels at 50°C, 55°C, and 60°C, plus an 8-hour auto shut-off for added safety during desk use.

Choose the temperature that fits your drink and routine with simple one-button control. The built-in memory function restores the last setting when powered on again, which is handy for daily use at home, at work, or in a small kitchen.

• 3 temperature gears: 50°C, 55°C, and 60°C
• USB powered for use with laptops, power banks, or wall adapters
• Waterproof tempered glass surface for easier wipe-clean care
• Even heating plate designed for flat-bottom mugs
• Automatic shut-off after 8 hours of inactivity

Compared to reheating drinks in a microwave, this heating coaster helps maintain warmth more consistently between sips. Unlike insulated travel mugs that keep heat locked inside, it works well when you want your drink open and ready on a desk while working, reading, studying, or taking calls.

The compact black design fits neatly beside a coffee grinder, pour over dripper, or other coffee gear without taking up much room. For the most consistent heating, use a clean, flat-bottom cup with full contact on the warming surface.
