Florence, the Treadmill Charger is an amazing invention! You can run and run and charge up all your devices at the same time, what a way to use your own energy! It is so fun to be active and energetic, and if you can use that power and energy to charge up your phone or iPad, what a bonus! I like your drawing, I can imagine the Treadmill Charger in real life! Great work, Florence, keep on inventing!
