I got this rear Origin 8 USB bike light from Redbeard Bikes in DUMBO a few days ago. I bought it because the brightness on the light blew away my light from two years ago and it charged from USB.

To test how it charged from solar, I connected it to one of our 3 Watt Solar Panels via our F3511-MiniUSB adapter for one hour in the sun — no more swapping out non-rechargeable batteries. It ran on its low setting for 3 hours and 45 minutes, enough for about 22 trips home as long as I’m hustling.

For those wanting the geeky details, we measured power flow from the panel into the battery and we were seeing 1.86 Watts (6.03V, 0.3A) on a slightly overcast day.
