USB Ultrasonic Diffuser Purifier for Car or Home with 240ml Capacity and Timer

This compact diffuser combines air humidification and essential-oil mist-making in a portable, USB-powered unit suitable for cars, offices, and bedside tables. Its small footprint of 115/68/68mm makes it unobtrusive while its 240ml water tank delivers up to 8 hours of steady mist output at 30ml per hour. The ultrasonic operation is quiet and energy-efficient, requiring only a 5V/1A USB source such as a power bank, laptop, or car charger. With a choice of four colours – black, green, pink, or white – it fits easily into any setting.

Features and Construction

The diffuser is built from ABS plastic with internal electronic components and a silicone seal for the water tank. It weighs just 150g net, making it easy to move between locations.

Material and Build

ABS plastic provides a lightweight but sturdy exterior that can withstand everyday handling. The silicone seal around the tank helps prevent leaks during transport, and the electronic components are designed for low-power ultrasonic vibration.

Size and Practical Fit

The product dimensions of 115/68/68mm allow it to sit comfortably in a car cup holder, on a desk, or on a nightstand. Its 240ml capacity is sufficient for several hours of continuous use before refilling, and the total gross weight of 180g makes it easy to take along in a bag.

Uses and Placement

This diffuser is designed for small enclosed spaces where air dryness or the need for aromatherapy arises. Its USB power source makes it independent of wall outlets in many situations.

Car or Travel Use

Place the diffuser in a car cup holder and connect it to a USB car charger for humidification on long journeys. The 30ml/h output adds moisture to the cabin air, which can help reduce dryness from air conditioning or heating systems.

Everyday Home Use

At home, set it on a desk, bedside table, or shelf. The low 2W power consumption means it can run for extended periods without significant energy use. The essential-oil function allows you to add your preferred fragrance to the mist.

Benefits and Buying Value

This diffuser offers practical value through its combination of portability, adjustable runtime, and simple operation. The timer function helps conserve water and power.

Reuse and Low Maintenance

With no disposable parts, the diffuser is reusable indefinitely. Cleaning involves rinsing the tank with water and mild soap periodically to prevent mineral buildup. The silicone seal is easy to wipe clean.

Why Choose This Product

Its compact size, USB power, and timer settings make it a flexible option for anyone seeking a small mist-maker for a car or small room. The choice of four colours allows some personalisation, and the 240ml tank provides a practical balance between capacity and portability.
