I need Help for a lego based generator
​
Base idea:
It’s going to be a LEGO vacuum engine that turns an electric motor to recharge a battery.
What I need help with:
How can I connect the LEGO electric motor to the battery so it can recharge it?
And how can I connect the battery to a USB port?
Goal:
I want the battery to charge while the vacuum engine is running (I know it probably won’t be very useful) so I can use it to charge my phone later.
Thanks for the help!
