Black cylindrical USB humidifier with color-changing LED light, 100 ml water tank

Humidifier 100ML USB

SKU CH-ZFHC-BRB87

A portable 100 ml USB humidifier with dual mist modes and seven-colour LED lighting for car, office or bedroom use

  • Compact cup-holder fit for easy in-car use
  • 100 ml tank gives up to 8 hours intermittent mist
  • Dual mist modes with 30 sec on / 15 sec off cycle
  • Seven-colour LED night-light with long-press dimming
  • Auto shut-off at low water for safe operation

Portable USB humidifier for small spaces

This 100 ml ultrasonic diffuser connects to any USB power source and fits standard cup holders, making it suitable for cars, desks or bedside tables. It runs without a built-in battery, so continuous power from a 5 V adapter or USB 3.0 port is required. Two mist modes and a seven-colour LED light provide both humidity and ambient lighting.

USB power and water-level limits

The unit needs at least a 5 V / 1 A supply; older adapters that only deliver 4.8 V / 0.6 A will cause the mist to stop or the LEDs to flash and shut down. Filling above the maximum water line also prevents mist output, and the device must stay upright to avoid internal short circuits. Auto-shutdown activates when the water runs low.

Replaces plug-in car fresheners and desk humidifiers

It upgrades from single-scent vent clips or basic evaporative pads by adding adjustable mist intervals and a colour-changing night light. The jump is worth it when you want both aromatherapy and a subtle glow in a compact, cup-holder-sized device that powers from the same USB ports you already use.

Questions about this item

Should I choose continuous or intermittent misting for longer runtime?

Intermittent mode runs 6-8 hours with 30-second mist and 15-second pauses, while continuous mode runs 4 hours.

What does the 100ML tank capacity mean for daily use?

The 100ML tank supports up to 8 hours of intermittent misting or 4 hours of continuous misting before a refill is needed.

What USB power standard does the diffuser require to operate correctly?

It requires a 5V/2A adapter, a 5V/1A car adapter, or a USB 3.0 port; older 5V/1A adapters supplying only 4.8V/0.6A may cause no mist or shutdown.
