300ml Ultrasonic Mini Humidifier with Colourful LED Lights – USB-Powered for Desk or Bedroom

This compact ultrasonic humidifier delivers a steady flow of fine mist to relieve dry air in your immediate workspace, bedroom, or home office. With a 300ml water tank, it provides up to 5 hours of continuous running or up to 10 hours in intermittent mode, so you can set it and forget it through a work shift or overnight. The small footprint (151.3 x 78.6 x 78.6mm) fits easily on a desk, nightstand, or shelf, and the built-in coloured LED lights add a soft, ambient glow. Power comes from any standard USB port – your phone charger, power bank, or laptop – making it truly portable and easy to position wherever you need it.

Features and Construction

Built from a combination of ABS, PP, and silicone, this humidifier is lightweight yet robust enough for daily use. Its ultrasonic technology produces a super-fine mist that disperses quickly into the air without creating wet patches nearby.

Material and Build

The main housing uses ABS plastic for strength and impact resistance, while internal parts are PP for chemical stability. A silicone seal around the tank opening prevents leaks. The overall build feels solid and well-finished, with a smooth exterior that wipes clean easily.

Size and Practical Fit

At 151.3mm tall and just 78.6mm square, this humidifier occupies little more space than a drinking glass. It slides neatly onto a desk corner, beside a monitor, or on a bedside table without crowding your other items. Its low weight (not specified but typical for this size) and USB tether mean you can move it from room to room as needed.

Uses and Placement

This humidifier is designed for personal space humidification – it’s not intended for whole-room use but works well for the area immediately around your desk, bed, or sofa. The optional coloured LED lights make it suitable for ambient lighting as well.

Home or Office Desk

Place it next to your computer on a work desk to combat dry air from air conditioning or heating. The quiet ultrasonic operation won’t disturb calls or concentration, and the USB power lets you plug into your laptop or a wall charger without needing a separate outlet.

Bedroom or Nursery

Use it on a nightstand during sleep. The 5-hour continuous mode covers a typical night’s sleep, while the intermittent mode can stretch to 10 hours with breaks. The colour-changing LED lights can be left on as a gentle nightlight or turned off if you prefer darkness.

Benefits and Buying Value

This humidifier offers straightforward relief from dry air at a low energy cost (just 3W) and with minimal maintenance. Its dual timer modes give you flexibility, and the USB power source means no bulky adaptor is required.

Reuse and Low Maintenance

Refilling the 300ml tank takes seconds, and the unit requires only occasional cleaning with a mild descaling solution to prevent mineral deposits. The silicone parts can be removed and rinsed. Between uses, store it dry to keep the internal components in good condition.

Why Choose This Product

If you need a small, quiet, USB-powered humidifier for personal use, this model combines a practical tank size, adjustable timer, and ambient lighting in one affordable package. The three-material build (ABS + PP + silicone) is typical for this class of device and provides reliable day-to-day performance.
