Frequently Asked Questions

Q: Can the USB cup warmer heat cold drinks from scratch?

A: No — this thermostatic heating coaster is designed to maintain the warmth of beverages that are already hot. It is not a kettle or boiler and cannot bring cold water or other cold liquids up to temperature.

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

A: The USB cup warmer requires a 5V/2A USB power source. It is compatible with laptop USB ports, desktop computers, USB wall adapters, and most USB hubs that provide at least 2A of output. Note: some laptop USB ports may only supply 0.5A–1A, which could reduce performance.

Q: How do I switch between the 3 temperature settings?

A: Once the warmer is plugged in, simply press the control button to cycle through the three temperature levels: 55°C (low), 65°C (medium), and 75°C (high). An indicator will show your selected setting.

Q: Is this USB cup warmer safe to use under a mug all day?

A: Yes, the NOCCLILI cup warmer is built with thermostatic control technology that regulates heat output consistently. However, as with any heating device, it is good practice not to leave it unattended for extended periods and to keep it on a stable, heat-tolerant surface.

Q: What mug sizes fit on the heating coaster?

A: The heating plate is 8.8 cm in diameter and the base platform is 11.2 cm wide, making it compatible with most standard mugs, cups, and small tumblers. It works best with flat-bottomed cups.
