About this item

• 【108kHz Ultrasonic Atomization & Micro-Mist Efficiency】 Precision 108kHz
• 2kHz resonant frequency generates 1–5μm ultrafine mist particles for rapid humidity diffusion; 1.5–2W low power consumption with 300mA max current ; FR-4 fiberglass PCB withstands repeated thermal cycles in DIY humidifiers and desktop plant terrariums; outperforms competitors with inconsistent frequency drift
• 【Intelligent Spray Modes & Auto-Protection】 Single press activates continuous spray for 4 hours (LED solid light); double press enables intermittent mode: 10s ON / 5s OFF cycling for 12 hours (LED blinking); triple press shuts down; integrated dry-run protection halts operation if water depletes or mineral scaling detected; resolves "unexpected shutdown" issues in peer reviews
• 【Type-C 5V PD Compatibility & Stable Operation】 Direct 5V
• 0.5V input via Type-C PD protocol (compatible with USB-C chargers and power banks); VBUS/CC1/CC2 pins support voltage negotiation; critical safety note : never connect to >5.5V sources (e.g., 12V/24V adapters) to prevent circuit damage; stable operation requires ripple <100mV and distilled water to minimize scaling
• 【Ultra-Compact FR-4 PCB & Heat Dissipation】 35×19×1.2mm footprint (smallest in-class) with 1.2mm FR-4 substrate resisting humidity-induced warping; 3.4g lightweight design integrates seamlessly into portable humidifiers and 3D-printed enclosures; aluminum heat sinks dissipate residual heat during extended use; not compatible with high-vibration Enviro nments (e.g., automotive engines)
• 【Rapid Troubleshooting & Maintenance】 Weekly white vinegar cleaning removes mineral deposits on atomizer plates; confirm 5V stable input with multimeter if mist weakens; ensure water level ≥25mm submergence and parallel disc alignment ; avoid hard water to extend lifespan beyond 6 months; incompatible with non-PD Type-C cables
