Or increased riding time required.
Going back to your comment about the Exposure Revo vs the Supernova E3 triple pro. They are both very bright, but the supernova edges it on the brightness of the brightest part. The output is the same but the Revo is nice and flat and even. I just like the brighter central area on the Supernova.
Increased riding time - only if the device charges at the lower power level or you charge a cache/battery first. I've read lots of stories of iphones and Garmins not functioning because the power being provided was too low.
