Product Information

About this item

• 【AI Auto Heating & Flexible Control】 With AI Beverage Detection, VSITOO S3 Ultra detects your beverage and automatically starts heating the moment you pour. Compared with conventional heated coffee mugs that require manual operation and limit you to fixed temperature settings, S3 Ultra lets you customize each of 3 presets separately in the VSITOO App from 120–150°F in 1°F steps. Let it heat automatically, adjust it with on-mug Button Control or use App Control.
• 【3 Custom Temperature Presets via App】 Unlike heated mugs with fixed temperature settings, S3 Ultra offers 3 Custom Temperature Presets. Set each preset separately in the VSITOO App anywhere from 120–150°F in 1°F steps, then switch between saved temperatures with Button Control for coffee, tea and more. Enjoy 2–4 Hours of Cordless Heating, while the Charging Base provides continuous heating.
• 【20oz Capacity, Fewer Refills】 The 20oz premium capacity provides more room for your favorite coffee, tea and beverages, reducing frequent refills during long work sessions, relaxing mornings and everyday use. Designed to fit comfortably under most home espresso machines and coffee makers, S3 Ultra delivers a premium drinking experience from freshly brewed coffee to all-day beverage enjoyment.
• 【Double-Wall Stainless Steel & Ceramic】 Built with Double-Wall Stainless Steel made from 316 Stainless Steel and finished with Food-Grade Ceramic Coating on both inner and outer surfaces to help preserve beverage flavor while resisting stains and odors. Smart idle protection automatically stops heating after 2 hours of inactivity by default and can be extended to 4 hours through the app. Additional protection includes BPA-free Materials, Dry-Boil Protection, Overheat Protection and IPX7 Waterproof Protection for reliable everyday use.
