Portable 300ml USB Humidifier
This compact cool-mist humidifier holds 300ml of water and runs from any USB port. It suits drivers, office workers and travellers who want personal humidity without a mains adapter. The cat-shaped body includes a colour-changing night light for bedside use. Two spray modes cover continuous or intermittent misting.
Simple One-Button Setup
Unscrew the top, fill with water, plug the USB cable into a laptop, car port or charger and press the single button to cycle through modes. The cotton swab must be fully soaked and left for 3-5 minutes before first use or mist will be weak. Auto shut-off activates when water runs low, preventing dry running.
Check Your USB Power Source
The unit has no battery so it needs a live USB port whenever it operates. Verify that your chosen port — laptop, vehicle socket or wall adapter — stays powered for the duration you need. No driver installation or app is required. Ensure the cotton swab is seated correctly after each refill.

Questions about this item
How do I know the humidifier is spraying correctly after I fill and power it?
After soaking the cotton swab for 3‑5 minutes and pressing the button, a visible cool mist should appear from the top vent; if mist is weak, re‑soak the swab and ensure the 300ml tank has water.
What comes in the box and what must I supply myself?
The unit includes the cat‑shaped humidifier, a USB cable and the internal cotton swab; you must provide a USB power source such as a laptop port, car charger or wall adapter.
Which spray mode should I choose for overnight use?
Press the button twice to select intermittent spray, which alternates mist bursts and pauses, and the auto shut‑off will stop the unit when the water runs low.
