Battery-operated devices that need to serve you in an emergency are dangerous. If those batteries are shot when the time comes to use the device, you might as well be holding a brick. That’s why we’re fans of Faradeus, a flashlight that charges when you shake it. No batteries. No USB cables. Named after Michael Faraday, the man credited with discovering electromagnetic induction, the Faradeus flashlight boasts a supercapacitor that gets energy from a magnet running back and forth across copper wire. How does it go back and forth? Again, just Shake Weight it up. The Faradeus flashlight is machined from a single piece of aircraft grade aluminum and is shockproof and waterproof. You can back the already funded project on Kickstarter right now.
