12oz Self Heating Coffee Mug

Vsitoo S3 – The Espresso Lover's Precision Heated Mug Finally, a self heating coffee mug designed for espresso with true precision. The 12oz S3 features a clear digital display that shows your drink temperature in real time, with 1℉ incremental adjustment from 120℉ to 150℉ — so you can dial in the perfect warmth for your espresso, cortado, or americano. AI Auto-Sensing detects your drink the moment you pour and starts heating automatically — no buttons, no apps, no setting. The compact 12oz size fits perfectly on your espresso machine tray, ideal for concentrated coffee drinks. Built with premium 316 stainless steel that resists coffee stains and odors. Fully IPX7 waterproof for easy rinsing under running water. Smart dry-boil protection pauses when empty and resumes when refilled. Designed in Delaware, USA.

• 【World's First Heated Mug for Espresso】The Vsitoo S3 12oz is purpose-built for espresso lovers — the perfect capacity for lattes, cappuccinos, flat whites, and americanos. AI auto-sensing technology detects when you pour and instantly starts heating at the ideal temperature. No buttons, no apps required — just pour and enjoy barista-level warmth at home or the office.
• 【Precision Temperature for Every Sip】Espresso-based drinks taste best when kept at the right temperature — the S3 maintains yours between 120-150℉ for up to 4 hours on a single charge. A single-touch control lets you choose between 3 precise settings, while the digital display shows your current temperature. Place on the included charging coaster for all-day warmth.
• 【Premium 316 Stainless Steel + IPX7 Waterproof】Unlike budget heated mugs using standard 304 steel, the S3 uses medical-grade 316 stainless steel — more corrosion-resistant and safe for all drinks including acidic espresso and milk-based beverages. The IPX7 waterproof rating means easy rinse-clean under running water. BPA-free with scratch-resistant coating.
• 【Smart Safety, Total Peace of Mind】Dry-boil protection pauses heating when empty and auto-resumes when refilled — no restart needed. Adjustable auto shut-off (2-4 hours) adapts to your day. Take it from your espresso station to your desk — the slide-resistant base and cordless design make the S3 your perfect daily companion for espresso enjoyment at home, office, or on the go.
