First, I have a couple of these little AA flashlights from Hong Kong
http://cgi.ebay.com/3-Watt-1AA-torc...2442578?pt=US_Flashlights&hash=item33637c9ad2
They are pretty bright for their size & price- and so far seem to be reliable.
I want to use this dynamo charger/radio to charge a set of AA batteries that I can use in the mini flashlights I have incase of emergencies.
http://market.solarrific.com/product_p/01108.htm
The specifications say "Charging external products: Voltage Output: 5.6 V Maximum output power: _ 2.5W Mobile phone talking time after 3 minutes cranking: 2-8 Minutes"
The device uses a round tip dc cable and comes with a normal size and mini-usb adapter. I will be using the normal USB adapter.
My question is about the compatibility of the Dynamo with the following products...
This usb charger charges 2 AA batteres in the '5V usb range' (in description) but seems to have no overcharging protection. I'm almost positive this will be compatible with the Dynamo Charger and it's 5.6v output
http://www.amazon.com/Targus-Usb-Aaa-Battery-Charger/dp/B0025X1ASG
I like this one more though (with overcharging protection) but the descriptions mentions nothing about 5v. Would there be any issues with using the 5.6v dynamo charger with this item?

Then there is this charger which has the positive side of partially eliminating self discharge. LSD cells they are calling them.

Is it realistic that 20 consecutive minutes of cranking from the specifications of the Dynamo Charger that I could atleast get an hour of charge in my 2 batteries for my mini flashlights? Or maybe even 1minute of power for 1 min of cranking?
They also make these single usb batteries but I don't think they could handle taking 5.6v themselves when an real AA battery is between 1.4-1.6v. Or would it recharge faster?

I'd really appreciate any educated suggestions!
