1. I want to see a plot [Power] vs [Speed], possibly based on a 28" wheel
2. Your claimed 2.34255W at 20km/h seems pretty low and however not enough to decently power-up even a very common gps such as a Garmin Montana 600 at its max backlight illumination
3. IP69 is irrilevant if I have a look to the IP00 usb connector
4. A minimum of a cache battery is fundamental to allow continuous and regular functioning of connected devices
5. Voltage protection (21V) is too low, you must accept the fact that not always you have a connected load
6. Pricewise it doesn't look to be much attractive

CONCLUSIONS
1. Test it in a more scientific way, not just on the handlebar of your bike keeping a multimeter in your hand.
2. Test it at multiple speeds with different types of load.
3. Test it varying among different dynohubs in such a way to see how it performs with different power generators.
4. Test it in parallel with some led headlight switched-on (with built-in overvoltage protection)
5. Finally make public in a clear way all the results of your tests, show your test set-up and plots obtained

Thank you.
