AFDEAL USB Mug Warmer – 3-Temp Smart Coffee Cup Heating Pad

Keep Every Sip Perfectly Warm — All Day Long

Never suffer through a cold cup of coffee, tea, or milk again. The AFDEAL USB Cup Warmer (Model: RST-77) is a sleek, intelligent heating coaster designed for your desk, home office, or bedside table. With three precise temperature settings and a micro-crystalline glass surface, it maintains your beverage at exactly the warmth you prefer — quietly and safely.

3 Precise Temperature Settings

Choose the perfect warmth for your drink:
