Product introduction

This is a multi-purpose emergency mobile power supply –hand crank generation. This kind product meets military basic three standards (dust-proof, waterproof, drop protection). This product can go without electricity and fuel for power generation in human dynamo supplies various types of electronic products. Field, field work, field trips, rescue operations, natural disasters, survival training, emergency communication, and long-term shortage of power, tourism, emergency power and other conditions apply. Primarily for low-power electronic devices supply power or charge for them, such as radios,PDA, cell phone, digital camera, MP4, MP3, radio, flashlights lighting and so on.  


Working principle

 Shake the hand crank, accelerated by the mechanical transmission system; drive the tombarthite permanent magnet three-phase AC generator, Rectifier, filter, regulator to obtain a smooth DC output


Product features

It adopts high-tech magnetic power conversion technology, has the advantages of compact size, high power, high efficiency. Housing made of high strength aluminum alloy composites, lightweight, strong and durable portability. The circuit using a wide range of output voltage, suitable for all 5v electric battery charging, uses the most efficient charging way—pulse charging to charge the batteries, fully activated battery and extended battery life and protection of the battery. This products can use alone, also can use with alternate battery, and DC-DC voltage conversion players or inverse changed players: used with alternate battery, can improve electronic products’ line continuation ability (line continuation ability is the extending using time of the battery).


Operation conditions


1.ambient operating temperature:-40 ° c-+ 60 ° c

2.relative humidity: 80%-90% (40 ± 2 ° c)

3.altitude: not more than 5000m
