USB Fan Speed Controller 5V with Adjustable Timer and LED Dimming

USB Fan Speed Controller with Adjustable Timer and LED Dimming This USB fan speed controller operates at 5V and gives you precise control over compatible fan motors and LED lamps. It combines adjustable speed regulation with a built-in timer function, making it a practical addition to desks, workbenches or any setup where consistent airflow and lighting control matter. Slow-Start Technology for Reliable Operation The integrated slow-start function gradually raises the output voltage when power is applied. This protects connected fan motors and LED lamps from sudden voltage surges, which can help extend their working life and keep operation smooth from the moment you switch on. Digital Voltage Adjustment and Timer Control A user-friendly digital interface allows you to adjust voltage levels quickly and accurately, so you can fine-tune fan speed or lamp brightness to suit the task at hand. The automatic timer lets you set a desired switch-off time, which is useful for overnight operation or timed sessions, helping you save energy when the device is not in use. Energy-Saving Display Option To minimise unnecessary power consumption, the digital tube display can be switched off with a simple double-click. This reduces light emission from the controller itself, which is particularly helpful in darker environments or when you prefer a discreet setup without compromising on control.
