Featuring large easy-to-read LED display design, this USB to DC power cable can allow you to know the output voltage value at a glance. This USB to DC power cable is practical, which can allow you to choose 9V or 12V voltage output to power the router through power bank to make you no worry about power failure. Made of high quality ABS, it is lightweight, wear-resistant and durable to use. The length of this cable is 80cm. It can also be applied to other device which is 5v power supply, such as small fan, desk lamp, solar panel, USB power pack, power adapter etc. Item Name: Power Cable Material: ABS Voltage Input: 5V Voltage Output: 9V/12V Maximum Current Output: 9V/1A, 12V/0.8A Output DC Interface: DC5.5, DC5.5 to DC3.5 Adapter Features: Wide Compatibility, Adjustable, Plug And Play Size Details: Cable Length: 80cm/31.5"(Approx.) Notes: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Warm Tips: 1. Do not connect the USB power supply port of the 9V/12V voltage increasing cable to the USB port on the computer; 2. The current output of the 9V/12V voltage increasing cable is less than 1A. If the current of your router/optical cat is greater than 1A, it cannot be used. 3. The conversion output voltage must be matched with the voltage of the electrical equipment, no side may damage the electrical equipment oh Package Includes: 1 x Power Cable 1 x DC5.5 to DC3.5 Adapter
