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

"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.

Excellent

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

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

You'd be surprised what creative uses a thing like this can have! I've attached it to a stationary bike in a youth center and strung lights overhead. So fun!

Power enough of a position lamp. Cannot illuminate Bicycle headlamp. Should have a rating of zero star

So far so good this worked out very well for putting a led light on my snow blower it didn't have a charging system on it so with a little welding to make brackets to mount generator so the wheel would ride against the main drive belt and it worked out very well so far

I'm don't use this to like supposed use but after short time is working exelent 🤣

Dynamo worked as described, quality seems good.
