The people who have to keep their Phones with them 24/7/365 find the option of a Dynohub and its Optional converters to generate a Small USB
charge current useful, are numerous enough to have several Companies Competing for sales..

This happens with the Lights Off , as 3w-6v output is not enough for Both loads at same time..




I have a Dynohub wheel on my Brompton , it goes into the Pub with me, I always have lights on the way home .

Just un fold it and go . streets are dark and traffic few, then ..


I did mostly Summer tours , daylight hours Riding most of them, got me far enough that seeking a place to stay or Camp
by late afternoon , was also enough time in the saddle for the day.. (only a Radio was my electronics things)

now to that Bike I added an LED battery light mounting place, It's also a very bright flashlight , too.
