Can I use A 9V power supply on A 12V router?
You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original. If you use one with significantly more voltage (and 12v is a full third more than 9v) then you might burn out your device.
Can I use A 9V power supply on A 5v device?
No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn. It could be however, that your adapter has an internal resistance causing the voltage to drop to ~5V, so it could work in this case, if the adapter can supply the needed current…
Can I use any adapter for router?
You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original.
Does voltage affect router?
It should not matter all the end equipment uses DC power and the power supplies in the equipment should be able to provide the proper dc voltage even if the ac voltage changes. If there were problems the modem/router would likely reboot or crash if it had a power issue it does not run slower.
Can I use adapter with higher amp?
5 Answers. Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
Can low voltage damage router?
no. do not EVER do that. It will damage your router – they are designed to run at specific voltages, and devices such as routers don’t have the best voltage regulation circuitry.
Does Wi-Fi work at low voltage?
Wi-Fi. These days almost every device in your office has some type of Wi-Fi capability. Low voltage wiring is used to set up entire Wi-Fi networks.
Can you use a 12V adapter on a 9V router?
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. In order to swap out chargers, 3 things must be the same:

Can you use an adapter with the same voltage as the original?
Your output voltage is wrong, which is the important part. You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original. I wouldn’t. It might work depending on whether there’s sufficient additional voltage regulation inside your router.
Do you have to match the voltage of the Charger?
No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device being powered or charged. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.
