The Power Pack & Charger is the solution to the PSP's limited battery life. Designed specifically to fit the PSP, this rechargeable unit snaps into the PSP's existing body grooves and connects into the AC plug. Not only does this power pack add more than three hours of gameplay, but it doubles as a secure stand that keeps your PSP in perfect viewing angle. Connect your existing PSP adapter to charge your sealed battery pack and your PSP in one go. Pass-through charging technology charges both the pack and the PSP in one charge.
