Car Diffuser Humidifier 300mL USB

A portable cool-mist humidifier designed for vehicle cup holders and small indoor spaces. It runs from any USB port and holds 300mL of water. Integrated colour-changing LED lights provide ambient illumination while the unit operates.

USB Power Cup Holder Fit Auto Shut-Off

The device plugs into a car charger, laptop or power bank so no dedicated outlet is required. Its compact footprint sits securely in a standard cup holder, freeing desk or console space. An automatic shut-off stops the mist when the reservoir is empty, preventing dry running.

Drivers Office Workers Light Sleepers

Suits anyone wanting humidified air and soft lighting during commutes, at a desk or beside the bed. Not for users who need a larger tank for whole-room coverage, adjustable mist levels, timer settings or essential-oil diffusion chambers.
