The Generic USB Mini Submersible 3-5V DC Water Pump 120L/H moves liquid through small-scale systems using a brushless magnetic drive. By operating on low DC voltage between 3V and 5V, the unit draws minimal power. This 120L/H pump fits DIY electronics and compact fish tanks where space is limited.
Key Features
- USB Power Compatibility: DC 3-5V operation via standard USB ports. Power banks keep it running during load shedding.
- Brushless Magnetic Drive: Engineering plastic construction with magnetic rotor. Reduced friction maintains the 500-hour working life.
- Ultra-Quiet Operation: Noise levels stay below 40dB during flow. Desktop fish tank fountains remain silent.
- IP68 Waterproof Grade: Fully sealed housing resists continuous underwater submersion. This prevents electrical shorts in deep aquarium setups.
- 80-120 L/H Flow Rate: Maximum vertical lift reaches 40-110 cm. The pump moves water for small hydroponics or Arduino projects.
Frequently Asked Questions
How to connect 5V mini water pump to USB?
Connect the lead wires to the red and black USB power lines. This setup draws between 100-220 mA from any standard 5V USB source.
Can this pump run continuously for 24 hours?
The brushless motor supports 24-hour operation but total mechanical life ends at 500 hours. Low 1.5W power draw prevents overheating during long cycles.
