kindly give me some advice if I can use 13.5 volts for Yamaha PSR-22 if the voltage input is only 9 to 12 volts only?

Adaptor for PSR 22
by: Alfred

Dear Cecilio: I bought a keyboard from Ebay and it came with an Adaptor which had a higher DC Output than that recommended in the Owner's Manual. I had no hesitation in buying a new Adaptor exactly as recommended, as the general advice on Adaptors is to use only those which match the required voltage of the keyboard. This advice is to obviate any undue (higher) voltage which probably will eventually have a negative effect on the keyboard.

Power Supply Replacement
by: Steve W

When using a replacement powere supply the original voltage supply should never be exceeded. This could potentially cause overheating if not burn out the board. Look for a unit with the correct voltage but also check the current. Even one ot two milliamps will make a difference.
Good Luck.
