Can I use 12V adapter for 9V modem?

You cannot use that adapter because it is outputting more voltage than the original (12v vs. 9v). This has a likely chance of burning out one or more of the components within the router. ... The output voltages must be identical.

How do you convert 12V to 9V?

To reduce a 12V circuit to 9V, place two resistors in series within the circuit. Find the difference between the two voltages (12V - 9V = 3V) to determine the total amount of resistance needed.

Can I use 5v adapter for 9V?

As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.

Is it OK to use higher voltage adapter?

Voltage too high – If the adapter has a higher voltage, but the current is the same, then the device will likely shut itself off when it detects an overvoltage. If it doesn't, it may run hotter than normal, which can shorten the device's life or cause immediate damage. ... This could cause the adapter to overheat or fail.
