I was looking for a spare battery for my PSP and I found these guys through google. I saw they had a rechargeable battery pack called THE POWER PAK. Its kind of like having a spare battery, this thing actually charges my PSP battery through the mini usb port, BUT also comes with these 6 other connecters that charge all kinds of stuff like cell phones and IPOD. Works great on a lot of my stuff. They had it at a really good price, shipping was fast/affordable, and I got a coupon to go back and shop at their site again. Professional. Good experience.
