Mini USB humidifier for personal spaces

This compact ring-shaped humidifier measures 51 mm across and weighs 40 g, making it suitable for desks, car cup-holders or travel bags. It draws 500 mA from any USB port or power bank, so no mains adapter is required. The white ABS body floats on water and begins atomising immediately after power is applied.

Build quality and daily connections

The unit is moulded from ABS plastic in a sealed doughnut form that resists spills when knocked over. A single USB-A plug supplies both power and control — there are no buttons, cables or replaceable filters to manage. Simply set the ring in a cup of water and connect to a laptop, power bank or car charger for instant mist.

Check before ordering

Verify that your chosen power source can deliver a steady 5 V at 500 mA; some older USB ports may limit current below this level. The device has no internal battery, so it must remain plugged in during use. Ensure the water container is at least 20 mm deep so the ring floats correctly and the mist outlet stays clear.

Questions about this item

What USB power standard does the humidifier use and what does it limit?

It uses a USB connection with a DC5V 500mA input, limiting operation to standard USB ports or power banks that can supply that current.

What are the physical dimensions and weight for placement?

The ring-shaped unit measures 51 x 51 x 20 mm and weighs 40 g, so it fits in cup holders, desk corners or small travel bags.

How do you start the humidifier and what step is often missed?

Plug the USB cable into a power source, then place the unit into a water container; it will float and begin atomising once the wick contacts the water.
