Need that next on-the-go gaming session to go all night? The new Extended PSP Battery from Blue Raven Technology may be your dream product. The snap-on, lithium-polymer, 4,500mAh battery pack aims to deliver as much as 15 hours of PSP playtime--a big step up from the 3 to 5 hours offered by the PSP's default battery. But the increased playtime comes at a cost: The Extended PSP Battery is about the same size and weight as the PSP itself (5 ounces for the battery vs. 6.2 for the PSP), and it costs a whopping $90. On the bright side, it uses the PSP's charger to juice up, so you won't have to lug another wall wart around.
We'll have a complete review in May, but the added weight--and weighty price tag--means this one is strictly for hardcore PSP devotees. That said, for anyone who's ever done one of those long-haul continent-hopping flights--New York to Dubai, San Francisco to Tokyo--having the option of tripling your in-flight time on Killzone: Liberation, SOCOM, or Metal Gear Solid certainly has its appeal.
Update: Blue Raven has followed up with a note that the MSRP for the Extended Battery is $100--although it can already be found online for under $75.
