Portable Ultrasonic Oil Diffuser & Humidifier 400ml

Portable Ultrasonic Oil Diffuser & Humidifier for Everyday Calm

This portable ultrasonic oil diffuser and air humidifier is designed to create a more comfortable, pleasant environment wherever you are. With a practical 400ml water capacity and a compact footprint, it delivers continuous cool mist and gentle fragrance diffusion suitable for bedrooms, home offices, work desks, or small living spaces. Its cute, modern design blends easily with a variety of interiors, making it as visually appealing as it is functional.

The ultrasonic technology operates with fine, quiet mist output, helping to maintain a more balanced indoor atmosphere. Add a few drops of your preferred water-soluble essential oil (if desired) to enjoy a light, even aroma that can support focus during work hours or relaxation in the evening. The built-in humidifier function introduces moisture into dry air, which can be especially useful during air-conditioned summers or heated winter months. This can help ease common discomforts associated with dry environments, such as tight-feeling skin, dry nasal passages, or a scratchy throat.

Powered via USB, the diffuser connects easily to laptops, desktop adapters, or power banks, making it convenient for use at your desk or on the move. The 400ml tank is sized for extended mist sessions without frequent refilling, yet remains easy to handle. To set up, simply unscrew the lid, remove and fully soak the cotton swab in clean water, then reinstall it before filling the tank and powering on. The device is designed to stop working automatically when the water level is too low, helping to protect the internal components and conserve energy.

Its compact size and charming look make it a thoughtful gift option for colleagues, friends, or family members who appreciate a more comfortable and pleasant-smelling space. Whether used as a bedside diffuser, a desktop humidifier, or a small accent piece in a living room, it offers a straightforward way to enhance the atmosphere of everyday environments.
