So, does anyone know how the rev up flashlights work?

I've been wondering for quite a while how those rev up flashlights work. The ones where you sqeeze the handle in and it revs, and the light is powered by the revving. What exactly is going on in there? As specific as possible, can someone explain this to me?

I'm pretty sure its just some gears that turn a small generator when you squeeze the handle. For every squeeze, it spins up the little generator.

On some lights there's an energy storage device attached to the generator.

Sometimes it's a small battery (chemical storage of energy) or, more often, a small capacitor (electrical field storage of energy). Needless to say these lights usually have a short runtime that diminishes quickly, owing to their limited storage capacity and rapid voltage drop.

The handle is coupled to a gear train which in turn spins a small dynamo, the energy
is stored in a Capacitor or even a small cell as in some of the long runtime models
