BFTNTO Smart Car Air Freshener Diffuser — 50ml Rechargeable Ultrasonic with Starry Projector & Auto On/Off

The BFTNTO 2025 Upgrade Smart Car Air Freshener is a rechargeable ultrasonic diffuser that automatically scents your vehicle, projects a starry light show, and offers four adjustable fragrance modes with a 50ml refill.

Compact and thoughtfully engineered for in-car use, this diffuser combines nano-atomization scent delivery, a vibration-activated auto on/off chip, and an ambient LED projector. It arrives with a 50ml perfume bottle, a Type-C charging cable, and a durable aluminum-alloy body that fits most cup holders. Whether you want subtle freshness for daily commutes or a more vivid aroma for weekend drives, the device adapts to your needs while conserving oil and battery life.

How does the auto on/off feature save fragrance and battery?

The built-in intelligent chip and vibration sensor detect when your vehicle starts or stops, powering the unit accordingly so it only runs when needed. This reduces unnecessary spray cycles and extends both perfume and battery longevity without manual intervention.

• Vibration sensor triggers automatic operation with vehicle movement.
• Stops when the car is off to prevent wasted diffusion.
• Conserves fragrance and extends device lifespan.

What fragrance intensity and timing options are available?

Choose from four distinct modes to match cabin size and scent preference: light, medium, strong, and continuous. Each mode controls spray frequency and duration, so you can set it for long trips or quick rides while managing perfume consumption.

• Light: one-second sprays every 10 minutes for a gentle scent.
• Medium: one-second sprays every 5 minutes for regular freshness.
• Strong: one-second sprays every 30 seconds for a pronounced aroma.
• Continuous: constant misting for 30 minutes, then automatic shutoff.

What lighting effects does the diffuser offer for atmosphere?

The unit combines a star-pattern projector with seven-color ambient lighting to create a calming or festive mood inside the car. Lights and projections can be used independently from misting, providing visual ambiance for evening drives or parked gatherings.

• Starry projector casts a constellation-like pattern on surfaces.
• Seven adjustable atmosphere colors for different moods.
• Light functions operate alongside or separate from scent mode.

How portable is the BFTNTO diffuser and how long does it run?

The diffuser’s compact shape slips into most cup holders and is lightweight for carrying between vehicles or into small rooms. A built-in high-capacity lithium battery supports extended use; a full charge provides long standby and operational time so you won’t need daily charging.

• Fits standard car cup holders and small spaces.
• Fast-charge Type-C cable included for quick top-ups.
• Extended battery endurance supports weeks of typical use on a charge.
