USB Thermostatic Heating Coaster with 3 Heat Levels

Keep Your Drink at the Perfect Sip Temperature

This USB Thermostatic Heating Coaster is designed for people who want their coffee, tea or cocoa to stay warm and consistent from the first sip to the last. Powered via USB and built with a thermostatic heating plate, it helps maintain a steady warming temperature (up to approximately 55°C on the highest level), so you spend less time reheating and more time enjoying your drink at your desk, bedside or home workspace.

Featuring three adjustable heat levels, this coaster allows you to fine-tune the warmth based on drink type, cup material and room temperature. A simple one-touch start makes operation straightforward, while integrated temperature control technology helps distribute heat evenly across the surface. The compact, flat design supports a wide range of common mug sizes and bases, and the anti-slip surface helps keep your cup stable during use. With its USB power input, you can connect it to laptops, desktop computers, power banks or USB wall adapters for flexible placement at home or in the office.

The coaster is designed for everyday use, with a focus on energy-efficient operation and consistent insulation performance. At approximately 11.5 × 11.5 cm in size and a low-profile height, it fits easily on crowded desks, nightstands or kitchen counters without taking up unnecessary space. It functions primarily as a drink warmer and coaster, providing a stable base while gently heating suitable containers such as ceramic mugs, glass cups and some metal cups.
