I'll be doing a three week trip next year mostly away from the grid. I've thought about dynohubs, but solar seems to be getting to the point where it is very competitive.
This is a 14W anker solar panel , though how it's 14-watt when it's also max 5V/2A I'm not quite sure.
Nonetheless, for $75 US it looks like a great deal, maybe a panel that can be used on the bike (though it's large), but also maybe a panel that is good enough to give you a significant boost just being used in late afternoons.
Anything better out there? I'll probably just be charging iphone/ipad mini/lights.
Not interested in dynohubs. I've gone that route before.
