Featuring an integrated step-up voltage regulator, this cable allows you to convert 5V input (from USB ports or power banks) to a stable 9V DC output, perfect for powering routers, Arduino boards, small electronics, LED strips, portable fans, and more.Its compact design makes it ideal for use on the go, especially for DIY projects or backup power setups. Simply plug the USB into a 5V power source and connect the DC plug to your 9V device—no software or configuration required. Features Step-Up Converter – Converts 5V USB input to 9V DC output Built-in Protection – Over-current, short-circuit, and thermal protection Plug & Play – No drivers or configuration needed Universal Compatibility – Works with routers, microcontrollers, modems, mini fans, LED devices, etc. Portable & Lightweight – Ideal for travel or emergency power solutions Package Includes: 1 × USB to 9V DC Power Cable Compatibility Notes: Use with USB power sources that can supply at least 2A for stable 9V 1A output. Ensure your device uses a 5.5mm x 2.1mm barrel connector and accepts 9V DC input. Not suitable for devices requiring more than 9W power. Important Notes: Not suitable for high-power 9V devices like larger routers or guitar pedals unless they draw low current (<1A). Ensure your USB power source can supply enough current — typical USB 2.0 ports max out at 500mA, USB 3.0 at 900mA, and USB chargers/power banks vary (some go up to 2A or more). Always check the polarity and voltage requirements of your device before use to avoid damage.
