Mini USB Humidifier for Home Car Desk – 300ml Tank, 6-Hour Runtime

Dry air in cars, offices, or bedrooms can be uncomfortable – especially during long drives or while sleeping. This Fireworks mini humidifier is a simple, portable solution that plugs into any USB port and runs silently for about 6 hours. With a 300ml water tank and a gentle spray volume of 30-50ml per hour, it adds just enough moisture to small spaces without creating puddles or wet surfaces. The compact 75x75x116mm size slips into a cup holder, sits on a desk corner, or rests beside your bed. Available in three colours – white, pink, and green – it matches most interiors without being intrusive.

Features and Construction

This humidifier uses a straightforward design focused on reliability and ease of use. The materials and specifications are chosen for daily handling and low maintenance.

Material and Build

The main body is made from ABS plastic, with a PP plastic inner tank and standard electronic components. This combination keeps the unit lightweight (around 120g) and easy to move. The ultrasonic atomiser produces a fine cool mist without heating the water, so it is safe to use near people and pets. The data cable is included, so you can start using it straight away.

Size and Practical Fit

At 75x75x116mm, this is a genuinely small humidifier. It fits inside most car cup holders, on a compact desk shelf, or next to a phone on a nightstand. The 300ml tank is not meant for whole-room humidification – instead, it targets your immediate breathing zone. The runtime of approximately 6 hours covers a full workday or a night's sleep, and the auto shut-off feature (when water runs out) prevents damage.

Uses and Placement

This humidifier is designed for personal use in small, enclosed spaces. Its USB power source makes it versatile across different settings.

Event or Professional Use

In a office cubicle, this unit can reduce static and dry skin caused by air conditioning. It is also useful for hotel rooms during travel – just plug into your laptop or a USB wall adapter. The quiet operation means it will not disturb colleagues or others in a quiet environment.

Everyday Home Use

Place it on a bedside table to ease dry throat or nasal passages during sleep. It works well in a child’s room for a subtle moisture boost. Because it uses USB power, you can even run it from a power bank in a power outage. The three colour options let you match it to your décor without it standing out.

Benefits and Buying Value

This humidifier offers straightforward value through reusable performance and simple upkeep.

Reuse and Low Maintenance

Just fill the 300ml tank with clean tap water, plug in via USB, and the mist starts within seconds. The unit requires no filters or replacement cartridges – just occasional rinsing to prevent limescale. The 6-hour runtime means you can fill it in the morning and not worry about refilling until the next day. When the water runs out, the device stops automatically, protecting the motor.

Why Choose This Product

For the price of a few coffees, you get a portable humidifier that works in your car, desk, or bedroom. The dual-voltage USB operation means it works internationally with the right adapter. The three colour choices and small footprint let you personalise your space without clutter. This is a practical, no-fuss accessory for anyone who regularly spends time in dry environments.
