I guess the Brunton in the link might do the job when AC recharged. It is basically a rechargeable battery pack.
Maybe
what we need is this, referenced in the current solar charging thread. Powerful, and priced right.
? You sure it won't keep a smart phone charged? A friend of mine has something similar to this:
http://www.walmart.com/ip/Accessory-...apter/17803218 and it keeps his smart phone running. He goes camping for a week and has to stay in touch with his work, plus goofs on the internet, and the battery in the phone last all week and remains almost if not fully charged. I use something similar and keeps my phone charged to when I go camping or weekend touring. I even tried to see if it would throw a charge back into the Cygolite Mitycross 480 by running down the light till the middle amber indicator came on, left it outside all day charging, when I turned the light on charge indicator was green, so it threw enough charge into the light to keep the charge level up and shut off the charger. Not sure how much more of a solar charging capability one needs. Sure it won't keep a laptop going, or if your constantly using the Smart phone, but you're not going to be constantly using the smart phone while riding! Or at least you shouldn't be using it while riding.
