5V USB Mug Warmer for Coffee & Tea

Help slow heat loss from an already-warm drink with a compact USB mug warmer for desks, home offices, and workspaces. Its low-profile heating surface is designed to maintain warmth rather than boil or reheat a cold beverage.

Key Features

• USB-powered 5V operation
• Designed for coffee, tea, milk, and water in compatible cups
• Compact white design for desk or countertop use
• Simple plug-in operation
• Model: HG-01

Power Requirement

Use a USB power source rated at at least 15W (5V/3A). A lower-power source may not provide effective warming.

Performance note: This product maintains the temperature of a beverage that is already warm. It cannot boil water and is not designed to heat a cold drink to serving temperature. Results depend on cup material, base shape, room temperature, starting temperature, and power source.

Safety: Use a flat-bottomed, heat-safe cup. Keep the warmer and USB connection dry, place it on a stable heat-resistant surface, and unplug when not in use.
