FAQ

Q: Does this mug warmer boil liquids or just keep them warm?
A: It is designed to maintain warmth, not to boil or rapidly heat cold liquids. For best results, place an already hot drink on the plate.

Q: What types of mugs work best?
A: Flat-bottomed ceramic or metal mugs work best. Very thick, double-walled, or heavily insulated mugs may reduce heating efficiency.

Q: Can I power it from a power bank?
A: Yes, as long as the power bank provides a standard USB output with sufficient current, the warmer and hub will operate normally.

Q: Is it safe to leave it on for several hours?
A: It is intended for regular desk use, but for safety and energy efficiency, switch it off when not in use or when leaving your workspace.
