Short answer: Available in Black and White, the JCLOUD A-311 V2 is a smart waterless scent diffuser for customers who want large-space coverage, a clear digital display, direct touch controls and optional Bluetooth scheduling. It covers up to 2,000 sq ft and uses a 180mL oil bottle for consistent home, office, studio or spa scenting.

A-311 V2 uses waterless cold-air diffusion to turn compatible diffuser oil into a fine fragrance mist without heat, water or dilution. The real-time display shows scent level, timer, work and pause cycles, Boost status and Bluetooth connection status, so you can understand and adjust the scent routine without opening an app.

Why choose the A-311 V2?

Visible smart control: Check the current settings and machine status directly on the digital display.
Touch control: Adjust power, timer, scent intensity and Boost Mode from the diffuser.
Nine scent levels: Start low and increase gradually to match the room, layout and fragrance.
Optional Bluetooth scheduling: Create repeatable scent routines from the compatible app when needed. Wi-Fi is not supported.
Large-space scenting: Designed for areas up to 2,000 sq ft. Actual scent performance varies with room layout, airflow, oil and intensity setting.
Waterless operation: Add compatible diffuser oil directly to the bottle. Do not add water or carrier oil.
