I'm looking to work out a way of charging my HTC hero from a dynamo on my bike for when away touring in remote locations.
I came across this:
Nokia UK - Nokia Bicycle Charger Kit - Overview
It comes with a 2mm jack, so won't fit the Hero, but I notice Nokia also do a converter from what I assume is a 2mm jack to a mini usb:
Nokia UK - Nokia Charger Adapter CA-146C - Overview
the specs for the Nokia charger seem to me to be the same as any USB charger:
Power generation:
Compatible with bottle type bicycle dynamos with 6V/3W and 12V/3W output
5.0V/450mA/15km/h. Maximum current 70mA
Charging starts at ~6km/h and maximum output is achieved at 25km/h. Charging stops when the speed reaches 50km/h.
Charging time depends on cycling speed, for example a Nokia 1202 with a 860mAh battery can be charged with about 20 minutes of cycling at a speed of about 10km/h (for the Nokia 1202 this would mean approximately 57 mins talk time or 74h standby time)
But can someone in the know just check that the outputs above are viable for any USB charged device.
Thanks
Phil
