About the JCLOUD A-311 V2 Smart Display Waterless Diffuser

The JCLOUD A-311 V2 is a waterless scent diffuser. It uses cold-air diffusion to turn compatible diffuser oil into a fine fragrance mist without heat, water or dilution. Oil goes directly into the bottle. Do not add water or carrier oil.

A digital display shows the scent level, timer, work and pause cycles, Boost status and Bluetooth connection status. Touch buttons on the diffuser control power, timer, scent intensity and Boost Mode, so the app is not required. A display-off mode reduces the screen's brightness.

The diffuser has nine scent levels, from L1 to L9, plus a Boost Mode. The optional Bluetooth app sets custom work hours, days and spray cycles. App control uses Bluetooth only, and Wi-Fi is not supported. It covers up to 2,000 sq ft, and actual performance varies with room layout, airflow, oil and intensity setting.
