Title: Jin's FD5 Dynamo Review
Post by: crazydoug on April 27, 2022, 01:14:47 pm
This came the other day, and I thought I would do a review and do some testing to see if it met the specs advertised.  Sadly, it didn't even come close.  It is rated up to 1 amp at 12 volts, and although it easily attained the 12 volts at about 2000 rpm, it would only light one 200 milliamp incandescent bulb.  I started with four bulbs in parallel at 200 milliamps each and it would not light them at all, and then went down, one step at a time, until there was only one bulb left, which it did light.  However, if you intend to use this generator in a model display with incandescent lighting, you'll be disappointed.  However, it will operate a number of smaller LED lamps.  250 milliamps seems to be the extent of the load it can carry. 

Still, I'm very happy with the generator.  It has a nice look, is a nice size for model engine displays, and has a price that can't be beat.

PM Research has one that is rated at 10 VDC @ 1A. Nice industrial look to it. Needs a large engine to power it to its max.

I have 2 of those. I machined the first one and decided it was worth the extra $$ to buy the next one ready to run. They work well, but I have never really done a load test.
