What It Is

The VSITOO S3-B is a 12oz heated coffee mug made from 316 stainless steel. It uses AI beverage detection to start heating automatically when liquid is poured. Temperature is adjustable from 120 to 150°F in 1°F steps via on-device buttons or a companion app. A charging base provides continuous power for all-day use at a desk.

Who It Suits

This mug suits espresso drinkers who want precise, automatic temperature maintenance for 12oz servings. It fits cortado, macchiato, latte and americano volumes. Buyers who need larger capacity for travel tumblers or who want a mug that runs indefinitely without the base should look elsewhere.

Deciding Spec

The 12oz capacity sets the serving limit. It matches standard espresso-based drinks but cannot hold a full 16oz or 20oz travel portion. If your routine requires more volume per fill, this is not the right size.

Questions about this item

How do I set up the VSITOO S3-B mug and charging base for the first time, and what is the common mistake to avoid?

Place the mug on the included charging base so the contacts align; the AI beverage detection will then start heating automatically when liquid is poured. The step users miss is keeping the mug on the base for continuous all-day power instead of relying only on the 2–4 hour battery runtime.

Which parts of the 12 oz mug will need replacement over time, and how often?

The leak-resistant lid seal and the 316 stainless steel interior are the wear items; the lid gasket should be inspected every few months and replaced if it no longer seals, while the steel body resists stains and odours for years without replacement.

What is the first limit reached during continuous heating at the highest setting?

At 150 °F the battery delivers roughly 2 hours of cordless heating before the mug must return to the charging base for all-day temperature maintenance.
