Frequently Asked Questions

Q: Can the USB heated mug coaster heat cold water or cold beverages?

A: No — this thermostatic heating coaster is designed to maintain the warmth of already-hot beverages. It will not bring cold liquids up to drinking temperature. For best results, pour your hot coffee, tea, or other drink first, then place it on the coaster to keep it warm.

Q: What type of cup works best with this drink warmer coaster?

A: A flat-bottomed glass or mug provides the best contact with the 8.8 cm heating disc, ensuring the most efficient and consistent warmth transfer. Cups with uneven or rounded bottoms may result in less effective heating.

Q: What power adapter do I need for the USB heating coaster?

A: You must use a 5V/2A USB power adapter. Using an incompatible adapter may affect performance or safety. Most standard phone chargers that output 5V/2A are compatible — check the label on your adapter before use.

Q: How do I adjust the temperature on the 3-speed heating coaster?

A: Simply press the button to cycle through the three settings. The coaster starts at 55°C, then advances to 65°C, then 75°C with each press. One more press after 75°C will turn the device off.
