About this item

• Features a two-wire output, compatible with 2-pin, 3-pin, and 4-pin fans (note: 3-pin and 4-pin fans only support voltage speed control, not speed measurement or temperature control signals). Compatible with both old fans and new devices, with no need to worry about interface incompatibility.
• Plug-in mode is disabled by default. Gently touch the switch to cycle through the following settings: 1st gear 5V (blue light, low noise) → 2nd gear 7V (white light, balanced) → 3rd gear 9V (red light, high wind) → Off. Adjust the speed as needed to balance cooling and quiet operation.
• 50cm cable length, supports power supply for 5V devices such as computer USB ports, power banks, mobile phone chargers, etc., without the need for an additional power source. Can be used on desktops, outdoors, or on the go, with low conversion thresholds.
• The black PVC control box is ultrasonically welded, making it impact-resistant and splash-proof. The typical output current is 1A, which is suitable for most fan power requirements, ensuring safety and stability and extending the service life of the equipment.
