I've obtained a recharging cable for my PSP that has a USB plug at the end rather than an AC adapter.
I have a Lithium Ion Battery Pack which i use to charge up my iPhone when it's low on power and I have a bunch of those wall plugs you get with Apple devices that allow a USB cable to be plugged in.
I'm wondering if I can use this USB charge cable on my battery pack and the wall charger without any damage to the battery of the PSP system?
Note: The PSP I'm mainly talking about is my First Gen PSP but I also have a PSP 2000.
