Dude, i found something in the net. It might probably help you in some ways though i'm not sure myself if it is really good or bad. But personally i think it's good. Cause so far so good, im not having any problems & im using it 4 over 3wks now.

Now dude here's what you need to do, you'll need to use your PSP without the batt. Instead you'll be using your charger as a source of power. It works for me, i read it from a forum in the net & makes your PSP less portable. Why?? because you can't clearly just leave the area where you charger is plug-in. But beyond that, you'll have unlimited time of playing since you getting your power directly from the charger itself & you won't have to worry about the fact/rumor that you'll damage your PSP batt wyl playing & while charging.

I only have one concern though, i'm still not sure if its is good for the PSP or not using that kind of method. i can't find any info about it on the net about it's negative effects. I hope by telling this to you & to others who would try after reading this would find an answer to my question, rather to our question.

Enjoy. By the way, im using a PSP slim aka PSP 2000.
