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!
