Mark, I could tell you a myriad of ways to go about doing that with near bout any solar panel, but your best bet from what it sounds like you are looking for is the Brunton Solarport 4.4 http://www.backcountry.com/store/BRU0148/Brunton-Solarport-44.html take a look at that link. It's a few more dollars than what this panel is, however, this lil d00d packs a punch! You got your USB, your AA & AAA recharger as well as a 12v/6v charger all in one package for just over a lb. (19 oz.) all in one slimline 9x6x1.5" package. For what it is, you can't ask for more unless you're looking for some higher wattage than that. But for some recharge batteries, I haven't found anything sweeter than this. And BC is carrying them for round 40 bux less than Brunton suggests. You gotta love BC for their great deals! Also, very important to note about this Solaris that you are looking at is that while it is listed as 6 watts here on BC I went over to Brutnton and found it to be rated at 3 watts. I talked to a gearhead about this who said he is looking into it in case BC has it listed wrong. However, I double checked the specs BC has for that solarport 4.4 against what Brunton has listed for it and they're right on the money. Its ironic I came across your question cuz I'm in the market for just this type of item...usb, aa/aaa recharger, 12 volt adapter so that I can run an inverter from 12v to dc power. This is great stuff...Im bout to scoop this guy up myself. Hope this helps!
