It's no big secret that the PSP's battery really doesn't last as long as we all would like. That becomes even more apparent when you're out on the road or taking a trip and don't expect to be near an electrical socket to charge the PSP. In comes the next option, a car charger.
Yeah, this seemed like a necessity to buy. For ten bucks, why not. Of course it's something I'll throw in the glove compartment and probably use it two or three times out of the year, but at least it's nice to know that when I see that dreaded low battery indicator and I'm out and about, I can hook it up to the cigarette lighter and be up and going. But like I said, it's something you'll use rarely more than likely. I've used it twice on camping trips.
