Frequently Asked Questions

Q: Can the USB cup warmer heat cold water or cold beverages from room temperature?

A: No — the NOCCLILI USB cup warmer is a thermostatic warming coaster, meaning it is designed to maintain the warmth of already-hot drinks (coffee, tea, milk, etc.). It does not have the capacity to bring cold liquids up to temperature. Start with a hot drink and the coaster will keep it warm for you.

Q: What USB power sources are compatible with this cup warmer?

A: This USB cup warmer requires a 5V/2A USB power source. It is compatible with laptop USB ports, desktop computers, USB wall chargers, and most power banks that support a 5V/2A output. Make sure your USB source supports at least 2A output for best performance.

Q: Which temperature setting should I choose for coffee vs. tea?

A: Most people enjoy coffee kept around 55–65°C, which is the first or second setting — warm enough to enjoy without being scalding. For herbal teas or hot milk, 55°C is often ideal. The 75°C setting is great for those who prefer their drinks extra hot and for teas that benefit from a higher steeping temperature.

Q: What size mugs fit on the heating coaster?

A: The heating plate is 8.8cm in diameter, so standard coffee mugs, ceramic cups, glass mugs, and most travel tumblers with a flat base will sit comfortably. The coaster itself is 11.2cm in diameter, offering a stable base for a wide variety of cup sizes.
