http://cgi.ebay.ca/Premium-Battery-...QQihZ018QQcategoryZ122516QQrdZ1QQcmdZViewItem Well I really want another battery for my PSP because I'm going on a road trip, and I can't get a car adapter because the outlets are already being used. This is supposed to be double the life as a stalk battery(10 hours I guess), and it says it's from the US, but it doesn't look like much... Has anyone ever bought something like this before? There's only a few feedback but they're all happy with the seller. The stamina battery from Sony is $30 CAD and taht's only 2200 mAh, which is only 20% bigger which it states on the package. What do you think?
