DC 5V Step Up to 12V USB fan Controller, with Switch and speed controller for 3/4 pin connections, 12 V 2 governor switch, connections

High Quality Materials The USB fan regulator uses tinned copper conductors for corrosion and oxidation resistance, ensuring stable power supply. The cable jacket is made of flexible PVC for heat resistance, abrasion resistance, flame retardance, flexibility and durability. Stable output: DC 5V step-up to 12V USB fan controller converts the standard USB-A 5V output into a stable 12V output to power 12V case fans, additional devices such as fan hubs and speed controller can also be used. EASY TO USE So no unplugging or software operation is required - great for DIY case modifications. The central part control module combines 5-12V voltage increase and switch and speed control, making it easy to control the fan. Compatible: This adapter cable is suitable for both 3 pin (DC) and 4 pin (PWM), cools a variety of electronic devices that output USB power after switching on (consoles, network devices, professional devices, etc.) Widely used: The USB fan controller is suitable for compact 12V devices such as case fans, additional cooling modules and front fans.
