Freeplay Energy - Energy for Life

The Freeplay self-charge system is built around a custom designed, highly efficient alternator.  The architecture of this patented system has been developed to maximize the ability of the user to convert human mechanical energy into stored electricity quickly and efficiently.

While the basis of Freeplay's superiority lies in the performance of this system, Freeplay has extended the engineering excellence to every aspect of the Sherpa LED.

The winder handle is made from tough glass reinforced Nylon and is designed, along with the grip of the flashlight, for comfort and ease of use.

The transmission (gear train) is constructed to high manufacturing tolerances from glass reinforced Nylon and Acetyl – dissimilar engineering plastics that dramatically increase the life of the gear train.  The transmission has undergone accelerated lifetime testing in excess of 500 000 cycles.

Under self-charge conditions the batteries receive a conditioning charge that negates the memory effect common to rechargeable batteries and similarly increases their useful life.  Accelerated lifetime tests on the batteries in the Freeplay self-charge system have reflected no significant capacity loss after 10 000 crank charge cycles.

The light source is a cluster of 7 ultra bright white 5 mm LED's.  These offer bright white light but with significantly higher efficiency and lifetime than incandescent lamps, and are rated at up to 100 000 hours.
