can using other AC adaptors break a PSP/battery?

I would think that as long as you keep the voltages the same, you should be fine. (The voltage is located above the DC input on your PSP and on the AC adapter under "output")

Yes. Power adapters often have different voltage and amperage provided. The way to check is, on your PSP I suspect you have a voltage/amp rating right by the place where you plug in the power cord. Make sure that this matches the adapter you are plugging in. I'm not absolutely sure you have the same model PSP (if there are new models) but this site I've provided provides what "may" be your PSP's required power. Again I would suggest you double check your model right by the voltage input to see if you have the same..... Good Luck. I hope it still works.

Check out this site. It's a wonder for PSP owners.

if it's the same voltage it's no problem i used a standerad Ac adpter once to charge mine.

Don't worry.

read the voltage if it's same it's ok if not your batery will be damaged may be even the system.

no
