DIY Dynamo + Solar mobile phone charger.

[HW777]

Hi, my name is Justin. I am a student whom is currently on project that requires me to combine a dynamo to an existing solar power bank. I have no prior knowledge in electrical, hence I would like to Seek your advices.

1) Dynamo + the chipboard (handles and gears not shown)




2) The solar power bank ( solar panel + the batt)




I have thought of detaching the chipboard from the dynamo and attach its positive/negative terminals to the respective wires on the solar panel(or the same connection points as of the solar panels to the power bank chipboard). But, I am afraid that it may damage the battery as the input currents will be different. Please help me, thank you!
