Shake flashlight

Shake what yo momma gave ya w/ this battery-less LED flashlight that uses magnetic energy and coils to give you 2 hours of light for a thrifty 1.5 minute-long shake session.

Not so sure exactly what model this is, but there's a slew of 'em if you google it. This one seems to have an exceptionally long light-life.

Thing is, it DOES have a battery. Shaking the flashlight charges the battery, and the battery will fail just like any other chargable battery in a few years. Instead of replacing the battery, most consumers will probably just throw it out, contributing to our waste problem. They should make the rechargable battery user replaceable and have more information on how to replace it instead of claiming that you 'never need to replace the batteries'.
