USB Cup Warmer

A USB Cup Warmer is a compact, electrically heated coaster designed to keep beverages like coffee, tea, or hot chocolate warm directly from your desk or laptop. Powered via USB, it typically features a low-profile, safe heating element that maintains a steady temperature—around 50°C (122°F)—without boiling the drink. Its non-slip surface and auto power-off features ensure both convenience and safety, preventing spills or overheating if left unattended. Lightweight and portable, it’s ideal for use in offices, home workstations, or dorm rooms, offering a simple yet effective solution for anyone who wants to enjoy a consistently warm drink throughout their day.
