Doing some looking and found the Goal Zero 10 recharging kit for $54 and some change with free shipping from West Marine. Everywhere else has them for $119...

We're lucky now, there are tons of 5v USB solar panels out there from 10-20w, which should do ~2.4A under bright sun, so look for one of those.

Unless you're charging up an AGM/SLA 12v battery, most of your stuff will be 5v USB.

With the plethora of USB NiMH chargers and li-ion chargers we have, that's the way to go.

Look at something like a Tomo V8-4 4x18650 power bank, to charge up your USB stuff, for not a lot of cash (you'll need four 18650s, however.)

With smaller solar panels, bigger is always better and the Goal Zero 10 is going to be slow, especially if you're in an area with NOT a lot of solar hours per day.

I bought the SunKingdom 14w folding jobbie and it does 2.5A under ideal conditions.  It was $40.  Instapark and Anker are both well regarded.

The NiMH charger that Goal Zero makes isn't very good.
