Portable 330ML USB Humidifier

This compact humidifier holds 330 millilitres of water and draws power from any USB port, making it suitable for bedrooms, offices, cars and travel. The nano-atomisation mist adds moisture to dry air while the gold-trimmed design fits cup holders and desktops. It serves both as a personal humidifier and an optional aromatherapy diffuser for essential oils.

LED Lights and Auto Shut-Off

The built-in colour-changing LEDs create a soothing ambient glow that can double as a gentle night light. An automatic shut-off sensor stops the device when the water level runs low, protecting the unit and giving peace of mind during sleep or work. No separate power adapter is required because the USB connection powers both mist and light functions together.

Check USB Power and Water Type

Verify that your chosen location has a USB-A port or a compatible USB charger capable of supplying the unit. Only clean tap or distilled water should be used in the 330ML tank; avoid adding oils directly unless the aromatherapy function is intended. The 4.7 inch height fits most cup holders, but confirm the available vertical clearance before placing it in a vehicle.

Questions about this item

How often will the 330ML water tank need refilling during daily use?

Refill frequency depends on mist output and runtime; the 330ML capacity typically lasts several hours before the auto shut-off activates at low water level.

What stops continuous misting first when the unit runs all day?

The auto shut-off protection triggers when the water level drops too low, halting operation until the tank is refilled.

How much heat or noise does the humidifier produce during extended operation?

It runs with whisper-quiet misting and minimal heat, powered by low-voltage USB for safe all-day use in bedrooms or offices.
