Details please read patiently, truthfully description:

This is designed for portable manufacturing.His career is not deceleration motor halfway, and with big motor to match the gearbox.

This volume weight is based on the portable single hand size and power and the design and manufacture,

Portable single hand hand generator, regardless of how good work, the average person can only continued to shake out about 10 w power, more output power to shake to continue to hold the generator output.

Portable use large motors with gear box, if is single hand will waste most motor performance can only continue to shake the 10 w, too heavy is not convenient to carry, is big also not convenient installation circuit and capacitance batteries, etc.

This hand generator performance is as follows:

Alloy gear with high speed bearing, high efficiency three-phase brushless dc generator

Reducer size 121 * 64 *Thick 25(mm);Brushless generator size: diameter of 38 *Thick 15Mm,

Transmission speed ratio 1:54 p.m,The output shaft diameter of 9.7 mm;

100 per minute hand forward around 25 v motor output voltage, short circuit current of 1.5 A, speeding to 40 v output voltage,

Generator output power 20 watts.

Foreign trade hand generator, the original no battery inventory of semi-finished products, no use.

Original installation battery of semi-finished products, inventory for circuit boards need to repair, no package circuit board is good or bad, only when the delivery hand test indicator light is normal show there is electricity, and normal smooth power generators.

Metal gear box runtime will inevitably some sound, use the grease eliminate part.
