Given the advent of new and higher end mobile devices. The need for portable charging devices is quite possibly on the rise. With that said, I am in the market for something that is both small, sleek and high functioning(can charge many devices, holds charge). Though I can sacrifice sleek in favor of size. Weight isn't an issue since I use a satchel.

If you have any recommendations, past experience, current experience, please post about it. I'm looking to charge a smart phone, BT headset, a PSP and a 7 inch tablet I acquired in China recently.

Some I've found so far:

Energizer Portable Charger for Smart Phones and More!

I-Up 5400 External Battery for Select Cell Phones

6400mAh External Battery Pack

Thanks for your input :D
