Portable USB humidifier with 220ml water tank, astronaut space design, and LED night light, offering 40ml/h fine mist output and low-noise operation for desktop or bedside use.
Portable USB Astronaut Humidifier: 220ml Tank with Quiet Mist and LED Light

Dry air in concentrated spaces like home offices, bedrooms, or dormitories can affect comfort. This portable humidifier offers a targeted solution, using a 220ml water tank to generate a fine mist output of 40ml per hour. Powered via a standard USB Type-C connection, it draws minimal power (1.5-2W) and operates at under 36dB, making it a discreet addition to any desk or bedside table. Its astronaut-themed plastic construction is lightweight at 203g, and the built-in colourful LED light provides a soft ambient glow, blending practical humidification with playful decor.
Features and Construction

The humidifier's design prioritises simple, reliable operation for personal spaces. Its compact form factor is engineered for stability and ease of use.
Material and Build
The main housing is constructed from plastic, contributing to the product's light weight of 203g and its portable, durable feel. The astronaut-themed shape is a key visual element, incorporating the mist outlet and an integrated, multi-colour LED light. The device includes a cotton swab filter that aids in mist diffusion; this swab must be soaked in water for 3-5 minutes prior to initial use to function correctly.
Size and Practical Fit
With dimensions of 110mm in width, 110mm in depth, and 119mm in height, the humidifier has a small footprint suitable for crowded surfaces. The total packaged size is 112mm x 112mm x 124mm. The 220ml water tank capacity is designed for intermittent use, requiring refilling after several hours of operation at its 40ml/h output rate. Its lightweight build and lack of an internal battery mean it must remain connected via the included USB cable to a 5V/1A power source.
Uses and Placement

This humidifier is intended for localised humidity control rather than whole-room coverage. Its specific features guide its optimal placement and use cases.
Event or Professional Use
The quiet operation and decorative LED light make it suitable for low-key professional environments like reception desks or therapy rooms where subtle ambiance is valued. The USB power allows it to be run from a laptop or portable power bank during events, trade shows, or in temporary office setups where mains power access is limited.
Everyday Home Use
At home, it is most effective on a bedside table, home office desk, or nursery side table to alleviate dryness near where you sleep or work. The LED light can serve as a gentle night light. Its automatic shut-off feature activates when the water level is low, providing a safety measure for overnight or unattended use.
Benefits and Buying Value

The value of this product lies in its focused functionality, ease of setup, and multi-purpose design that combines humidification with mood lighting.
Reuse and Low Maintenance
Maintenance involves regular refilling of the 220ml tank and occasional cleaning. The cotton swab is reusable. The device's water-shortage protection helps prevent damage from dry running, promoting longer functional life with basic care. No filters or consumables beyond water are required.
Why Choose This Product
This humidifier is chosen for its specific combination of portable USB power, compact astronaut design with LED lighting, and quantified mist output. It suits users seeking a small, quiet humidifier for a single zone that also acts as a decorative item, without the need for complex installation or permanent wiring.
