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!!!!

Great batteries!
Just as good as the one that originally comes with the psp. I highly recommend it!

Not as slim as you'd hope
I bought this for my PSP Slim and was hoping they'd made some new revolutionary battery pack that was slim enough to fit in the same amount of space. This is not the product. In fact I'm pretty sure it's the same PSP battery pack from the Phat model and was shipped with a free cover. The power output is 2200mAh compared to the PSP Slim's 1200mAh. This is an increase of 80% more play which will come in handy when playing games that last for house like RPGs.

The additional weight output however is a little annoying and since its bigger than the original battery, it sticks out the back a little. As a bonus though the new battery cover adds a bit more grip so it'll have less chance of slipping out of your sweaty hands

Tis a shame that your PSP Slim will now have less style and will add 3mm of thickness. Aside from that, great product

PSP
Man IT IS Awasmone It IS way better than the MAX Power one so get it now.
