Fine, it's no power plant, sure. But seeing a PSP's abilities as a handheld (this is quite important for my apologia ), its battery performs very well. Also, my experience was based on spontaneous cumulated handheld gaming. You on the other hand described gaming behavior that's beyond simple portable pick up and play on the bus or where ever, but tells of something you planned. When I know I'm gonna play for hours with my mates I can be expected to bring some cables.
