Hello
I am working on a project to charge a small battery say of 3.5 Volts and 1000 Milli Amp through cranking/wind up but I am not able to figure out what dynamo is required and how much time I would have to crank in order to draw the required power(3.5 Watts) in order to charge the battery completely.
Please help me with this! thanks!
