I have a 12v wall power supply, but need a 9v power supply
Is there an easy way to change the output from 12v to 9v by simply adding a resistor?

What kind of power supply is it?I have a 12v wall power supply, but need a 9v power supply

How accurate does the 9v have to be? How accurate is the 12V?Sorry.
I need 9V DC output.....1Amp
The power supply I have is 12v 2amp output. The 2Amps is ok. I just need to lower the voltage.
It's just your basic Wall Wart common 12v Power supply that you might get with a modem or other device.
I know. I have probably 100 of them in boxes here and there but after going through ALL of them, I can't believe that I don't have a single 9V Wall wart....tons of 12v ones tho. But I can ASSURE you....when I was looking for a 12v wall wart a few months back....I couldn't find a single 12v Wall wart either among those 100. I have no freaking CLUE how that happens. I could have 1000 and not have THE ONE I'm looking for.....lolOr you could go to a second hand store and buy a 9V wall wart for $1
I have about 10 pounds of wall warts which accumulated over the years, but I don't suppose you want to wait a few decades for your junk box to get full.
