Exactly. 5W of charging is bumping against useless for current electronics.

The solar panel that I’m testing is looking pretty good. 500g, $75. At 45N latitude (I.e. pretty far north) in early April, it puts out 11W in hazy overcast, ~3-5W in high overcast without even getting it perpendicular to the sun. Going to USB either on the dynamo or on the solar panel is a big hit on efficiency.
