the one i saw had a radio, light (solid or blinking), a panic alarm, and cell phone charger. i just pictured myself with a bar mount version riding at night, headlight died, so i hand crank for a few minutes i got a blinkie, a radio, and charging my cell phone on my way home. 'twas a neat picture it was. i didn't know they were less than one watt ewwww! thats kinda pathetic. the one i saw was 3 led's so i'd imagine more than 1w but it didn't really say. the hub dynamo ones sound a lot better, especially if theres some sort of quick release so that you don't have the resistance all the time. also if you could make it power other stuff... say a radio and a cell phone charger?
