Line length: 5V universal: 1 meter; 1 meter;9v12v GM: 1 meterDC polarity: outer negativeness
first step,
View the voltage and current at the bottom of the router, cat, and switch. The voltage is 5V selected 5V universal. It is 9V -selected 9V -free, and 12V is selected for 12V. If the voltage is 9V12V, the current cannot be greater than 0.8A; 5V is not limited.
Buying guidelines:
1. View the voltage and current at the bottom of the ADSL, router, and the switch. The voltage is 5V. 5V is universal. It is 9V -free for 9V.
2. DC plug specification: 5.5mm in diameter, choose universal; if the diameter is 3.5mm, please select the corresponding voltage and 3.5mm conversion head; (3.5mm plug and andcell phoneearphoneThe size of the plug)
3. The products of this shop do not distinguish between routers, switches, and light cat brands. As long as the voltage is the same, products with a power of not more than 10W can be used.
product description:
1. USB input voltage: 5V;
2. DC output voltage selection: 5V, 9V, 12V;
3. DC plug specification: 5.5*2.1
【The difference between three lines】
5V direct:Simple power cable, USB input is 5V, and the output of the power supply DC plug is 5V.
9V booster line:With a lift component, the voltage of the USB input 5V through the component, the voltage to 9V voltage0.8~1A
12V direct:With a lift component, the voltage of the USB input 5V through the component, the voltage to 12V voltage0.8~1A
