Overall Cyclist Additional Requested Power to compensate for :
- Dynamo Losses
- Charger Losses
- 5Vdc USB Connected Loads
... and, as far as real dynamo dragging is concerned, with the new AC/DC converters available today promising to be capable to easily deliver 5W at 20 km/h, well it becomes very realistic to have an equivalent of 10W overall additional dragging, in other words A+B+C+D > 10W !!!
