Mega Battery Pack X5 3600mAh
Not worth US$ 10.90, totally useless. Battery life over 48, bullshit. I just throw 10.90$ away

Mega Battery Pack X5 3600mAh
My first impression of the Mega Battery was that it felt like it weighed roughly the same as the 1200mah genuine Sony battery. I was therefore skeptical of the Mega Battery's claim of 3600mah. I would have expected a true 3600mah battery to have weighed atleast double that of the 1200mah genuine Sony battery.

Putting this battery to the test indeed proved that it's battery life was inferior to even the 1200mah genuine Sony battery.

Other than low battery life, the Mega Battery works with the PSP Slim no problems. It should be noted that the Mega Battery also bulges out from the PSP quite abit. In my opinion, the added bulk and low battery life are not worth the cheap price. I would rather pay more for a better performing battery, preferably with less bulk.

So yeah, you really get what you pay for. Dirt cheap price - low performance.
