FAQ Hand crank mobile power bank

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.    

Working principleand crank mobile power bank

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 featuresHand crank mobile power bank

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);

used with DC-DC voltage conversion players, can converse the fixed output voltage into different output voltage,

thereby to adapt different voltage requires of electronic equipment;

when used with inverse changed players, can converse DC output into AC mains.  Hnd crank mobile power bank
