Frankly, your PSP becomes a whole lot more functional in terms of what you can do with it. It’s really that simple. Using a Pandora battery is a very common thing to do and more and more people use one every day. The benefits outweigh the costs, at least for most PSP users. There are forums dedicated to the topic of modifying your PSP with Pandora batteries, downgrading your firmware in order to increase your PSP functionality, and so much more! With a Pandora Battery you can play games on your PSP that you can’t otherwise, you can run programs on your PSP that won’t work otherwise, and you can milk your gadget for all that it’s worth!
But as always, don’t just take my word for it, check out the forums, check out the decently large sized online Pandora Battery industry, read what people are saying! Also, note that you cannot find Pandora batteries on eBay, because for some reason they’ve been banned there. But at any rate, I think you get the idea. There are a lot of people developing their own PSP programs / unlocking software, and they are willing to help you downgrade your firmware for free with their software, at least for the most part, so that’s another great thing about using a Pandora Battery!
