Where low voltage direct current is required dynamos are still used and make for excellent survival products. Hand cranked dynamos are used in dynamo flashlights, cell phone re-chargers, and other man powered equipment for recharging. It all started back in 1831 when Michael Faraday invented the first generator.

It was an amazing achievement in science. Michael Faraday was a talented scientist who made amazing contributions to the field of electromagnetism. Faraday's law is magnetic flux changing in time creates a proportional electromotive force.

Using this law Faraday was able to create the generator. Renowned scientist Hippolyte Pixii applied Faraday's law and built the first dynamo based on Faraday's principles (magnetic flux changing in time creates a proportional electromotive force).

The Dynamo is a generator that produces direct current with a rotary electrical switch known as the commutator. The commutator periodically reverses the current. The dynamo radio flashlight is a great survival tool and it is now available as a 4 in 1 survival product.

This dynamo radio flashlight contains 3 bright LEDs, Am/Fm radio, emergency siren, and cell phone charging capabilities with an adapter. The high efficiency dynamo system allows one minute of winding to create enough power for 1 LED to last an hour and a half or 3 LEDs to last for 30 minutes. Winding for 3 minutes will give your cell phone an average of 5 minutes of talk time. This dynamo radio flashlight is a great survival item for your home, automobile, RV, boat, office, classroom, and workplace. The dynamo radio flashlight 4 in 1 is also a great addition to your survival kit.
