    The product reviews say it is crap.

    Whatever happens, I'll keep y'all informed! I'm leaving in about an hour.

    I have tried the solar chargers for my phone while camping and the two I have tried just have not done the job.

    I'm wondering just how you know that the iPad's battery is less than 1800mah... I could be wrong, but what I see quoted is that the iPad battery is rated at 25Wh... so presuming about a 4V cell voltage, that's 6.25Ah.... more than THREE times that 1800mah...

    Hm... That math makes sense. Anyhow, end of the first day, no need to charge yet - still at 100%

    8:42 pm on the first evening, used the iPad with my iPhone navigation App (iGo using generic Hama car charger) to get here. We had a huge storm that damaged the tent (a branch fell on it), but the iPad is still at 99%

    This Amzer at 13Wh, 3500mah, looks somewhat better, though still only half the ipad's capacity...

    Amzer 3500 mAh Battery Backup Solar Charger - Fommy.com

    guess you could buy two...

    the guesstimated 6.25ah capacity of the ipad corroborates your 20% fill measurement of that Solio... at 1800mah... you have to factor in less than 100% efficiency...
