It simply adds more playing time
If you noticed that your psp slim and lite is always running out of juice in a couple of hours, this is "the solution".

You must buy it
I got another four ours of fun. It's something everyone must have !

Double the time double the fun
As title said. It's a a bit big but can give you a better grip on PSP. Still,two times the playing time is wort it all. A must get for PSP owner.

A Necessity For All Users
This is a great product, it's definably worth the extra thickness for almost 8 hours of battery life, I already had one from my old PSP but this has the extra cover to suit the slim & light

VERY LONG LASTING
This battery is very long lasting and is better than the original battery that came with my psp slim. This is an original Sony 2200mah battery. GREAT PRODUCT!!!!
