    So far I think it is great. Your kits are well thought out. I was looking for a good small knife blade to put in my Altoids tin. Your idea of sharpening a hacksaw blade is genius. I never thought of it. How well would that portable solar panel charge a laptop? I am ok if it takes all day, but it would be great to have access to all my saved info.

    The solar panel I have only puts out 5v AC. Laptops take 110v or 220v AC. There may be a way to run a laptop with 12v DC by adapting the power supply but I haven't tried it though.

    Actually they don't. The transformer that acts as the power supply runs on 110vac stepped down to 19.5vdc at ~3 amps(for mine, others vary from ~15vdc to ~24vdc). As for charging from 12vdc my laptop can use this http://www.amazon.com/Charger-Pavili.../dp/B004ARP28O I was hoping for a portable solar panel like what you have that would either do 19.5vdc or 12vdc that I could use the above adapter for. I am trying to avoid carrying too much in the BOB if possible. Thanks.

    Sorry, I wrote that incorrectly. The power supply takes in 110/220 and converts it to DC.

    The ~20v could be had from the 12v by making a simple DC/DC converter with an oscillator, filter, and power regulator, which would be much more efficient than running 12v-inverter-power supply. The supply you linked does exactly that (and would work better than any design I could come up with, I'm sure).

    Yeah, I am looking for a portable solar alternative though.
