When I travel I use my iPhone heavily, especially to keep track of and upload to the blog. I have a couple small recharge batteries I can slide into my pocket, but this looks like a better solution to what I have used so far. This could be a great gift/stocking stuffer.
This is the Duracell Powerhouse Charger (2000 mAh). It has a a mini-micro USB that will pop-out and a USB out. You can recharge from two devices at the same time. You can find this at a lot of stores, but I would appreciate it if you would use this link.
It’ll charge any device that takes power over USB. That means hauling cables around, right? This was my solution for cable-tangle when travelling: mini cables. They took a lot of clutter from my bag and pockets. And if you are really looking to detach from walls but keep using those small gizmos, try one of these.
From my constant war against cables and running out of power when out and around.
