G.I. 12 V 6 W Bicycle Nickel Plated Iron Dynamo Generator

Very nice product and build quality with metallic friction wheel. Contacts are iron (rusting results failure) so be sure to connect directly with copper wire to make it work for years

Good product with good packing

"it solved the purpose .. I had to demonstrate the generation of electricity through motion of wheel for college project. Thanks Amazon"

I even could not give a star rating.The product not only poor, it is not at all working, show 0.1V when spinning.

It produces Ac not not dc ...Diod and capasitor should be added..

Excellent

Don't know the reason stopped generating just after about 4 months , but in the first week produced sparks and blowed out few bulbs of my circuit , dissatisfied with my product

Good product, really strong overall. The packaging could be improved but overall it's a good product.
