Well I just wanted to post this real quick, I bought one of these Pelican Power Brick's for my PSP and thought some of you other PSP owners might be interested.
the short story: It does exactly what it says.
The long story: It's an external battery, with approximately double the capacity of the PSP's stock internal battery. You use the AC Adapter/charger that comes with the PSP itself to charge the power brick. Approximate charge time is about four hours. The power brick has a little green LED light on it to indicate when it's charging as well so you know when it's fully charged.... I didn't even expect this little feature but it is much welcome.
Once charged, unplug it from the charger and plug it into your PSP. The PSP will behave exactly as if you have just plugged in the AC adapter. It will go into charging mode if not fully charged, and if already fully charged will run off the power brick instead of the internal battery (in the menu it will say something like 'power source: external).
It does seem to provide roughly twice the PSP's internal battery life... I'm getting about 8-9 hours running strictly off the power brick as the direct power source (in other words NOT using it to charge the PSP's battery as it's been fully charged this whole time) before the PSP would switch over to it's internal battery. So that's 8 hours PLUS the usual 3-5 hours from the internal battery before you have you recharge... SWEET.
Other pros of the power brick: it is very compact and not TOO heavy, measures about 2.5" by 3" by .5"... easily fitting in your front or back pocket. The cord supplied with the brick to connect it to the PSP is about 3 feet/1 meter long, just right to reach from your pocket up to the PSP when you're holding it at chest level playing it. Another surprising feature is that the power brick has a place to attach a wrist strap (like the PSP's own wrist strap). Not sure if anyone would use this but hey at least it's there.
Another BIG advantage of using the power brick, is that, just like when running the PSP off of the AC adapter, when you are running off of the power brick you can turn the PSP's screen backlight up to the FOURTH, brightest brightness setting, which is not accesible when running off the internal battery. By the way, that 8-9 hours I quoted? That's with me ALWAYS running at the fourth brightness setting... the PSP screen just looks even more amazing at this very bright setting.
It also seems that you can charge the brick and the PSP itself AT THE SAME TIME OFF OF THE SAME AC ADAPTER. So if you've really gone an extended time, drained the brick completely and also the PSP's internal battery, you don't have to worry about charging one then switching to the other, just plug the adapter into the brick and the brick into the PSP and leave it for roughly 6-7 hours and both will be fully charged. SWEET!!!
The ONLY downsides I have on this wonderful little brick is that the raised, chrome colored Pelican logo is just too cheesy for me, but really as long as it stays in your pocket who cares. The only other downside is that the top of the brick gets VERY hot while it's charging. I thought maybe my brick was defective but after googling around I found that this seems to be common to all of them.
Anyways... I wholeheartedly recommend this product to anyone who owns a PSP even if battery life hasn't been an issue for you, if only so that you can experience the joy of always running on the fourth brightness setting which is GREAT for darker games like Metal Gear Acid and Twisted Metal. And at only $20 I feel it is a VERY good deal... the only unknown factory is lifespan and that's the only one I'm worried about. Cheap rechargeable batteries tend to fall off in capacity pretty rapidly and that would suck if that would be the case with the brick.
