Just curious... How is your 3G connection out in the wild? I've never had any luck 20 miles outside of gas and food..
I bought the Zagg Sparq 2.0 and it will do another 60%+ of an iPad charge. I've just got mine a few days back and have used it only slightly but it's a great backup solution. Plus for my wife's iPod, our cell phones it's also handy.
Though for renewable energy sources I to would like a decent solution I can have in my bag and use as I need it.
NumbLock's heart was in the right place, but his math was off a little in terms of power rating.
I hear very good things about the PowerGorilla and the SolarGorilla, for charging devices from cellphones to laptops when you're off the grid. A couple of people I follow on Twitter use them and speak very highly of them (though I haven't used them myself)
The PowerGorilla is just a compact, portable battery that stores a charge which you can transfer to your portable device using an appropriate connector (dozens of adaptors come with the PowerGorilla). You can charge the PowerGorilla from the mains before you leave home and then top it up using the SolarGorilla, a solar powered electricity generator.
I'm thinking of buying them myself.
Really interested in solutions...we are off camping for new years and have a beachfront site...and no power. I could go a park myself in the camp kitchen for hours while the phone, camera and I pad charges...but would love a better solution.
12V chargers may be more efficient than inverting to use AC. I get 12V chargers for everything I want to charge in our camper. Again, you can power them with 8 D-cells when necessary.
Check walmart if you have one close by, go to automotive and where they keep car batteries, there are portable jumpers/battery packs that have a 12 volt car plug and most have inverters for 110 built in. A lot cheaper than most small battery packs.
