It cannot heat cold or room-temperature liquids. Always pour a hot drink before placing it on the coaster.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What USB power sources are compatible with this mug warmer?\u003c\/h4\u003e\n\u003cp\u003eA: The coaster uses a standard USB plug (5V\/2A input, 10W) and works with most USB power sources including laptop USB ports, USB wall adapters, desktop hubs, and power banks. Just ensure your source supports at least 2A output for best performance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do the 3-speed temperature settings work?\u003c\/h4\u003e\n\u003cp\u003eA: The coaster features three selectable heat levels. Each step adjusts the surface heating intensity, allowing you to fine-tune warmth to your preference — whether you like your coffee mildly warm or consistently hot at the full 55°C constant temperature setting.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the heating coaster safe to use on wooden or delicate surfaces?\u003c\/h4\u003e\n\u003cp\u003eA: The ABS base is designed to direct heat upward toward your mug rather than downward. However, as with any warming device, it is advisable to place it on a heat-resistant, flat surface and avoid prolonged contact with sensitive materials like untreated wood or plastic tabletops.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
