DHRUV-PRO Metal 2-Pic Dynamo Or Generator High Speed Motor For Science Projects Experiment (2)

The quality of this item is good. This gives output but since this is actually low power generator, this generator needs a booster module to work properly and to provide useful output for further use. The functionality of this generator is good but it lacks mounting holes for screwing up this generator with external base. This needs clip mounting and not the screw mounting. To charge the mobile it’s better to use a diode and a capacitor at the output and then attach it to a booster module. So whenever it’s rotated by some external forces it will give useful 5v for batteries charging. The current output and thus the power output of the module solely depends upon the rotation of the generator. So more rpm generates more current and power output. This can also be connected with the mppt solar charging module, which will give best results. Using this generator as a wind turbine generator is very easy. As the speed of the wind will increase the output power will increase. Since this generator can generate low voltage only at low wind speeds, 12v solar charger module is not suitable. However the 3.7v mppt Solar charger module is great for this generator. This generator will also need to be well guarded against bad weather and rain. Rain can easily destroy this generator if not properly protected. In Vawt Mode weatherproofing doesn’t seem possible but hawt Mode can be made weatherproof. Thanks!

I like this product but l want more fast delivery because when ineed it it doesn't come to our house after order it took 15 days to come

Nice working generator it can easily generate 1.5 to 8v by fan's wind. overall working good.

Superb working

One peice is not working . Replacement time is gone due to covid 19. I try after 1o days but Amazon customer service is not available, so no any way to ded product accepted by me. Anyone purchase this product after satisfaction.

For Science project.Good workingThank you.Arun

Very good. Working as a generator

good
