Can I run a 12V device on 9V?

If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.

Can I use a 12V power supply on a 9V router?

I wouldn’t. It might work depending on whether there’s sufficient additional voltage regulation inside your router. But the adapter you’re considering using puts out a higher voltage than the original, 12v versus 9v, and stands a good chance of burning up your router with higher current than intended.

How do I step down from 12vdc to 6vdc?

It’s possible to step 12 volts down to 6 volts by incorporating a pair of 10,000-ohm resistors into the circuit. Cut two lengths of wire, and strip each wire of 1/2 inch of insulation at each end. Attach one end of the first wire to the positive terminal on the power supply.

Can you use 12V adapter for 9V speaker?

You can’t use a 12V adapter to power a 9V guitar pedal. A pedal that only handles 9V can be destroyed by using a 12V adapter. It’s possible for a power supply to ruin your pedal even if you get the voltage right.

Can I use 12V 1a for 9V 0.6 A?

No, a 12V Adapter provides too high a voltage for the intended application (9V). It is a gamble you will need to assume.

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.

How do you reduce voltage?

To reduce voltage in half, we simply form a voltage divider circuit between 2 resistors of equal value (for example, 2 10KΩ) resistors. To divide voltage in half, all you must do is place any 2 resistors of equal value in series and then place a jumper wire in between the resistors.
