USB to DC power cable allows you to charge your device anytime and anywhere. 8. Three kinds of line difference: - 5V straight-through: Simple power cord, USB input 5V, power supply DC plug output 5V. - 9V voltage boost wire: With a booster component, the USB input voltage of 5V through the component to boost to 9V, current within 1A. - 12V straight-through: With a booster component, the USB input voltage of 5V is boosted to 12V through the component, and the current is less than 1A. 9. Warm tips: - Do not connect the USB power supply port of the 9V/12V booster cable to the USB port on the computer - The current output of the 9V/12V booster line is less than 1A. If the current of your router/optical cat is greater than 1A, it cannot be used
