VSITOO S1 Smart Insulated Water Bottle, Black, 15 oz (14.8 oz), UV-C Self-Cleaning with Temperature Display

The VSITOO S1 is a compact 15oz insulated stainless steel bottle with an automatic UV-C cleaning system, temperature display, and long-lasting rechargeable battery for hands-free, safer hydration on the go.

The VSITOO S1 blends smart germ-reduction technology with travel-ready insulation in a purse-friendly shape. Built with a double-wall stainless body and BPA-free interior parts, this bottle uses an AI-driven UV-C cycle to refresh the drinking surface, displays real-time liquid temperature, and lasts up to 30 days per magnetic charge. It’s IPX7 rated for everyday splashes and sized to fit backpacks, briefcases, and cup holders.

How does the automatic UV-C cleaning work?

AI sensors detect usage patterns and trigger short ultraviolet-C cycles to sanitize the mouth area without user intervention. Safety features cut power if the cap opens or if the UV-C light is directed toward a person, and the cleaning resumes only when the bottle is upright and closed.

• AI sensing starts cycles based on opening and movement
• UV-C lamp targets the drinking area, reducing surface contaminants
• Automatic shutoff when the cap is open or light faces outward for safety
• Cleaning resumes when upright and securely closed

What temperature and battery features does the S1 offer?

The S1 gives an instant visual readout of liquid temperature and includes a responsive touchscreen for manual controls. A magnetic charger replenishes the internal battery, which can support normal daily use for up to 30 days between charges.

• Color-coded temperature display for quick checks
• Touchscreen panel for starting a cleaning cycle or checking settings
• Magnetic USB charging for convenience and reliability
• Long runtime—up to 30 days on a single charge under typical use

Will the S1 keep drinks cold and is it durable enough for travel?

The S1’s vacuum-insulated double-wall construction maintains cold beverages for up to 24 hours while keeping the exterior comfortable to hold. Its compact 15oz capacity balances portability with enough volume for daily hydration, and the stainless-steel shell is finished to resist scratches.

• Double-wall vacuum insulation preserves cold for up to 24 hours
• 15oz size fits purses, school bags, and most cup holders
• BPA-free drink-contact materials for safer reuse
• Scratch-resistant finish and IPX7 water resistance for everyday wear
