Thanks guys. Yes, I'm looking for a portable battery-powered charger for my mp3 player and cel phone, that I can carry in my edc backpack and not need to rely on the grid for. I like that cigarette light model too though...

So many options. Thanks for these recommendations. I have notoriously bad luck when it comes to buying electronics so I really appreciate your suggestions. I may cope-out and assign this task to my techie hubby.
