Hi jags!
While The Plug III shows higher output at all speeds than the Plug II, it isn't a lot more and is a bit higher at 15kph/9.3mph, then declines toward similar performance to the II until it makes provides more power around 23kph/14mph and retains its higher output thereafter.
The absolute difference in power isn't much...what differs is the speed at which it is available. For example, at maximum output (5.0vds @ 500mA):
~11.5kph/~7mph = Plug III
~14kph/~8.7mph = Plug II+
~18kph/~11mph = Plug II Classic
~21kph/~13mph = Plug I
The Plug II+ is a marked improvement over the Plug I and Plug II Classic when touring at slower speeds; the Plug II+ (which I have) is really worthwhile for charging at slow speeds on gravel, dirt, and long uphills. The Plug III is an incremental improvement over the II+.
will there be a video on the complete set up do you think.
Not to worry, jags; setup is extremely easy. The connections go: Dynohub > PAT II > The Plug III. It all just "plugs" together. The Plug itself simply replaces your threadless steerer's top cap. It may be necessary to replace the star-fangled nut with Tout Terrain's removable unit, but not always (if the "petals" in the SFN align to pass the wire). So long as there is enough clearance under the plug to prevent the wires from being crimped at the connector, you're good to go.
Best,
Dan.
