The TUTT Mug Warmer uses intelligent USB-powered heating technology to keep your coffee, tea, or other beverages at your preferred temperature. It features 3-level temperature control, allowing you to easily switch between low, medium, and high heat (typically ranging from 40°C to 60°C) with a simple touch sensor. This means you can enjoy perfectly warm drinks whenever you like, whether you're at your desk, in the office, or at home.

The TUTT Mug Warmer is designed to be compatible with most flat-bottomed cups and mugs, especially those made of ceramic, glass, or stainless steel. For optimal performance, it's best to use cups with a base diameter of up to 8.5cm (3.3 inches). Avoid mugs with uneven bottoms, plastic cups, or insulated containers, as they may not transfer heat as effectively.

The TUTT Mug Warmer includes built-in safety features such as automatic shut-off after several hours of use, overheat protection, and a non-slip, heat-resistant surface to prevent accidents. Its wireless base design reduces clutter, making it both safe and tidy for office desks, bedside tables, or kitchen counters.

This mug warmer doesn't have an internal battery, so it requires being plugged into a USB or Type-C power source. You can use it with a laptop, power bank, or USB wall adapter, but keep in mind it needs constant power to keep your drink warm.
