• It's the amount of charging done that results in a resistance in your dynamo.

    But isn't the voltage and current drawn by a charger always going to be the same?

    Ie, an iphone charges at like 5v and 1 amp right?

    So if you plug it in when the battery is flat and charge it until it's full and then unplug it'll have drawn 5v at 1 amp for say an hour or so.

    If you leave it plugged in all the time and the charger maintains the battery at 100% it'll draw 5v/1amp all the time.

    No?

    I have kind of wondered whether I make things harder for myself by leaving my lights on all the time. I thought that in setups like mine where the on/off switch is on the light, the hub always provided power and therefor had the same resistance. You had to have a switch on the hub (is this even a thing?) that turned power generation on and off to get a difference in the resistance.

  • On all my dynamos, I find it hard to feel the resistant when riding (on or off) however I can feel the vibration when I turn on the light/e-werk/etc.

    The switch is usually on the light/device rather than on the hubs itself.
