    You never mentioned the obvious -- a DC car charger. So you must be backpacking? Regards a solar charger, I have a .5A at 12V panel that measures about 15" square. So that would be 6 watts. Obviously a 10 watt panel would be nearly twice that size. And charging circuitry probably doesn't exceed 50% efficiency, so bigger still. Seems like your disappointing test results were on the money.

    I'd carry both an AC charger and a 2amp car charger and hope for opportunities. My Kensington 2A car charger is half the length of a cigarette lighter plug and can use the existing AC usb cable. So no hindrance packing it along.

    Actually, I wanted to talk about that. The cheap little Hama charger is the unsung hero of the trip. For convenience sake, I use my iPhone navigation software on my iPad and despite the enormous power draw of these types of apps, it worked just fine - no "not charging" messages.

    I'm car-packing, meaning both backpacking with a car base camp if you will.

    I found a site that is offering a complete iPad-specific filding panel charger solution, but was hoping for something more local.

    Just found this: QuickerTek USB Charge Monitor/Activator (scroll down to see the 10 Watt Foldable Solar Panel). Still pricey ($250), but it does have the output necessary for an iPad. They claim, "Our 10 watt solar panel charges as fast as Apple's 10 watt wall charger that comes with the iPad."

    Two years ago I purchased a Black & Decker device called Power to Go,its a little bigger than an Ipod but after charging it will re-charge cell phones,Ipods and maybe even charge a iPad.
    Output is 115V AC-60Hz 20 watts, USB output 5V DC 350mA. You can plug in a regular electrical plug or a USB plug, great when there is no sun.

    As I understand it you need 5V x 2A. 350ma won't cut it. But maybe the 115V x 20w output would power the 10w ipad ac charger. Dunno how long. In my experience you ought to derate all mfg claims by half to avoid disappointment.
