Hey - i'm a recent (second hand) psp owner and looking to buy a second PSP battery for long plane trips - does anyone have any recommendations as to what i should get? ie. should I get a genuine Sony battery, or is one of the third party batteries the better bet for value / performance? I see there are some chunky 4300 MAH batteries (made by Max i think) which i reckon should offer a fair bit of juice, but i'm told they stick out of the back of the psp a fair bit and are a bit uncomfortable to play games with. What do you guys do for extra power on long journeys? Any brands to stay away from? Any advice or comments appreciated. Thanks!
