5V Pass-Through: A simple power cable where the USB input is 5V, and the DC power plug output is also 5V.
9V Step-Up Cable: Features a step-up component that boosts the 5V USB input voltage to 9V at 0.8–1A.
12V Through-Type: Features a voltage-boosting component that elevates the 5V USB input voltage to 12V at 0.8–1A.
1. Check the voltage and current ratings on the bottom of your ADSL modem, router, or switch. If the voltage is 5V, choose a 5V universal power supply; if it’s 9V, choose a 9V universal power supply; if it’s 12V, choose a 12V universal power supply.
2. DC Plug Specifications: For a 5.5mm diameter plug, select the universal type; for a 3.5mm diameter plug, choose the corresponding voltage and a 3.5mm adapter. (The 3.5mm plug is the same size as a mobile phone headphone jack.)
3. Our products are compatible with routers, switches, and optical network terminals (ONTs) of any brand, provided they share the same voltage and have a power consumption not exceeding 10W.
