Bought it for $5 today. Supposedly the external battery bumps your bat life up to 20 hrs, but that is of course probably bullshit. Anyway, anyone heard of these things essploding PSPs, or is it relatively safe (albeit awkward and unattractive)? I'm charging it now, so really who gives a fuck if it works or not, it was only 5 bucks, but still, I like my face without molten plastic stuck to it so I'm asking.
