There is no need for 27.5W but there is for 8-10W. That should be
reasonably possible, else the dynamo would have smoked out during their
testing.


If all you're powering are head and tail lights, 10 watts should be
sufficient. However, if you're powering other devices (GPS,
smartphone, rear view camera, electric shifter, fog horn, etc), then
more power is better.


I also have to power an MP3 player. No smart phone since I won't likely
buy one until they can function as good as a GPS devise even while
off-grid.


We're already there. Lots of off-grid GPS/mapping apps. No need to use
data or have a data connection. Topos available too. Not free.

Is it as good as a dedicated GPS? Not really because the internal GPS
antenna on a phone is inferior, but for outdoors a phone is good enough.

You really need to get with the program and buy yourself an iPhone 7+,
and iPad Pro with LTE data, a Macbook, a Mac Pro, an Apple watch, and an
Apple TV. Wait a few months and drive down to Cupertino and buy
everything at the new Apple store.
