USB to DC Booster Cable with 9V/12V Output Switch

USB to 5.5mm DC Booster Cable - 9V or 12V Output is a simple way to run compatible higher-voltage DC devices from a standard 5V USB source. Plug it into a computer USB port, USB battery pack, or other 5V supply, and the integrated boost converter raises the voltage for devices that need 9V or 12V DC input.

A built-in selector switch lets you choose between 9V and 12V output, while the onboard display shows the selected voltage so you can verify the setting before powering your equipment. This is useful for test benches, portable setups, and small electronics that use a barrel-type DC input.

The cable comes fitted with a DC plug and includes a 3.5mm / 1.35mm adapter for added compatibility. Please check your device voltage requirement, plug size, polarity, and current draw before use to help avoid damage.
