5V to 9V Booster Cable for Mini UPS

This booster cable for mini UPS can convert 5-volt input to 9-volt output. This is useful when you need 12 volts but only have a 5-volt power source available, such as a USB port, to power a device. The cable usually contains a small circuit that increases the voltage. Typically, this helps you use your mini UPS with devices that require higher voltage.
