TSUJ 4010 5V USB Cooling Fan

The TSUJ 4010 is a compact 5V USB fan built with a dual ball bearing for continuous cooling of small electronics. It draws 0.08A from any standard USB port, making it suitable for hobbyists, technicians and anyone needing targeted airflow for components such as routers, single-board computers or projector enclosures.

Practical limits of USB 5V power

The fan operates strictly within the 5V USB supply, so total airflow is capped by the port’s current limit and the 0.08A draw of the motor. It cannot be used where higher static pressure or larger air volume is required, and it offers no speed control or temperature sensing beyond the fixed voltage input.
