Bicycle Dynamo Universal Charging Cable

I asked about this in the Lighting and Electronics section but no one was interested. Maybe some of you in the touring section might find the possibilities of this more interesting. I am actually wanting to use this in a tour I plan to take in January on a trip throughout Florida. I wouldn't mind having something like this to charge my cell phone, mp3 player, etc.

Has anyone used one of these before? I wouldn't mind having one if it actually works. With the adapters listed below I could charge pretty much anything that I needed on the road.

Does anyone have an actual source to buy them here in the US?

I'm considering the same item but no user reviews on the product. No distributors in North America so purchasing is via Pedal Power direct. Payments are made via Paypal and they ship using UPS.

There is another similar product from Germany:

https://www.jawetec.de/index.php?content=bikecharger

I Googled and found one english review:

https://bla.obda.net/wordpress/?tag=jawetec

Comparing both, I'm amazed at how compact the Pedal Power solution (charging cable) is compared with the JaWeTec version. Both pieces are meant to convert the dynohubs rotational energy from AC to DC, so how can the Pedal Power circuit be that much smaller?

Send mail to Norman at norman.field@gmail.com. I think he is the US rep.

If you can DIY electronics here is a combination USB charging circuit as used in the product above and an LED headlight if desired. The switch selects the headlight circuit, off, and USB charging.

Well since I did not find a review anywhere wither, I wrote one I will probably more in-depth review once I use it for a few months. Some initial thoughts are here.

What voltage NiMH batteries? Are you using them sort of as a voltage limiter?

All AA Ni-MH batteries are 1.2 volts dc. The batteries internal impedance will place an increasing load on the dynamo as voltage exceeds 4.8 volts dc with 4 batteries connected in series. This effectively limits dynamo voltage to 5.2 volts dc, which is within USB power standards.

At this year's Eurobike trade fair BUMM introduced a new product that should be perfect for you: https://www.bumm.de/docu/361e.htm
It will be available October and will sell for about 140 Euros. You'll probably have to order it directly from Germany. Or maybe ask Peter White, as he seems to sell a lot of BUMM products.

Thanks for the heads up.
