Charging on the Go.
I am looking for the best solution on charging on the go.
I posted about a site that has AA battery chargers for iPad, Solar chargers, and large capacity external batteries for iPads.
They are really intriguing but some a very expensive.
Whats your thoughts?
When you say "on the go" do you mean in a car? Or away from a vehicle?
If it's in a car, you can simply get a DC/AC power converter that plugs into your accessory port or a compatible USB power plug in your accessory port as well.
If you won't have access to that, I would say the chepest option would be one of those Energizer AA battery packs with some extra rechargeable batteries. Like you said, most of the other options are pretty expensive.
Look around for a power inverter. I've got one in my truck (750 watt) I use to power my laptop and other things on long road trips. It's got two A/C outlets and two USB charging ports.
