USB-powered water pump for small aquariums

This DC 5 V brushless pump draws 2.4 W and delivers a flow rate of 250 L/H with a lift of 2 m. It connects directly to a USB port for simple installation in desktop fountains or nano tanks. The submersible design keeps operation ultra-quiet for living spaces.

Replaces noisy or oversized AC pumps

The jump is worth it when you need silent circulation in a compact reservoir and have a USB power source available. It is not suited for large ponds, high-head plumbing or installations that require mains-voltage hardware.

Questions about this item

What USB power source does the 2.4 W pump require?

It runs from any standard DC 5 V USB port or adapter that can supply at least 2.4 W.

How do you prime the brushless pump so it starts moving 250 L/H?

Submerge the unit completely, ensure the outlet is below the 2 m lift limit, then apply power — trapped air is the only reason it stalls.
