Portable Mug Warmer (USB)

USB Portable Mug Warmer is a compact, easy-to-use warming plate designed to keep your drinks at an ideal sipping temperature throughout the day. Compatible with flat-bottom ceramic cups, glassware, and stainless steel mugs, it provides gentle, consistent heat, perfect for coffee, tea, or hot chocolate at your desk or bedside. It features adjustable high and low heating modes with a temperature range of 40°C to 60°C, allowing you to control warmth based on preference. A built-in 1 to 9 hour timer adds convenience and safety, automatically switching off after your selected duration. Designed with a water-resistant surface for easy cleaning, it’s practical for everyday use, though it should not be fully submerged or drenched. Not suitable for double-wall cups, plastic cups, or thermos flasks, as these materials can reduce heating efficiency. A simple, modern solution for keeping your drink warm longer without reheating.
