Mini USB Humidifier 300ml for Desk and Car with Two Spray Modes

This mini USB humidifier is built for small spaces where a full-size unit would take up too much room. It measures 73 x 73 x 132mm and holds 300ml of water, making it suitable for a desk, bedside table, or vehicle cup holder. The unit runs on DC5V=1A with a rated power of 2W and connects via the included USB data cable. It offers two spray settings: continuous mode, which runs for up to 3 hours before automatic power-off, and intermittent mode, which sprays for 3 seconds and pauses for 5 seconds, lasting up to 5 hours before shutting off automatically. A seven-colour night light can be turned on or off with a long press. The humidifier is available in grey, pink, or white.

Features and Construction

The construction uses ABS, PC, and electronic components. The 300ml tank provides a defined water capacity, and the two spray modes give a choice between steady output and a pulsed pattern. The button controls both the spray mode and the night light. All claims here are limited to the stated specifications.

Material and Build

The outer housing is made from ABS and PC plastics, with internal electronic components for power regulation, spray timing, and LED lighting. The atomising piece at the spray mouth must not be punctured. The included sponge rod and bottom spring are part of the water delivery system and should be kept in place during use. The unit is powered by USB at DC5V=1A and rated at 2W.

Size and Practical Fit

At 73 x 73 x 132mm, the humidifier has a small footprint that fits on a desk, shelf, or car cup holder. The 300ml tank is sized for short sessions: up to 3 hours in continuous mode or up to 5 hours in intermittent mode. The USB cable allows connection to a laptop, power bank, or USB wall adapter, though only the cable is included.

Uses and Placement

This humidifier is intended for personal spaces rather than large rooms. It can be placed on a work desk, bedside table, or in a vehicle. The night light function adds a visible glow in dark settings. The automatic shut-off in both modes helps prevent running after the water is exhausted, though the unit should not be left unattended for extended periods.

Event or Professional Use

In an office or study, the humidifier can run in continuous mode for up to 3 hours, covering a typical focused work block. The intermittent mode extends operation to up to 5 hours, which may suit a longer shift. The compact size means it does not crowd a keyboard or monitor area. The seven-colour light can be switched off if a neutral appearance is preferred.

Everyday Home Use

At home, the unit can be used on a bedside table or during travel in a car cup holder. The 300ml tank is easy to refill, and the first-use instructions require soaking the cotton swaddle for 1–2 minutes. Only tap water or mineral water should be used; pure water can affect fog output. For first operation, fill to about 90%, let it stand for 3–5 minutes, then start.

Benefits and Buying Value

The main practical benefits come from the defined tank size, two spray modes with automatic shut-off, and the compact dimensions. The included sponge rod and USB cable mean the unit is ready to use after the initial soak. The night light adds a secondary function without requiring a separate device.

Reuse and Low Maintenance

Routine care is limited to soaking the cotton swaddle before first use and using the correct water type. The sponge rod is replaceable, and a spare sponge stick option is listed separately in the colour choices. No other maintenance claims are made because the source does not provide them. The ABS and PC housing can be wiped clean, but no specific cleaning agents are stated.
