Bikes: 1940s Fothergill, 1959 Allegro Special, 1963? Claud Butler Olympic Sprint, Lambert 'Clubman', 1974 Fuji "the Ace", 1976 Holdsworth 650b conversion rando bike, 1983 Trek 720 tourer, 1984 Counterpoint Opus II, 1993 Basso Gap, 2010 Downtube 8h, and...

I recently spent $23.15 to buy this:


Generator Bicycle Bike Dynamo w USB Charge for Cellphone Mobile 12V | eBay

If that link doesn't work, I'll tell you it's an ebay sale consisting of :

1. a 12v sidewall dynamo with mounting hardware
2. a short coaxial wire with bare wires at one end and a 3mm plug at the other, that connects the dynamo to
3. an aluminum box with a standard USB outlet
4. a truly frightening adapter with a standard USB plug at one end and ten different plugs at the other.

Of these, I have no use for either no. 1 or 4, but the other two are neat. No. 2 connects No. 3 to the dynamo hub.

I have not used it much, yet, so can't really comment much, but initial tests show that it will definitely charge my phone.
