Decided to gather everything (almost) I know so far about the small wind turbines from China, and what to expect from them and what will you get for the money.

Time codes.
00:00 - intro
02:30 - small S3 wind turbine type
06:58 - M3 or SM3 wind turbine, still small, but slightly bigger
12:04 - M4, M5, M6, M8 and M10, or SM5, SM6 or SM5000, SM6000, depends on how they call them. I'd call them small medium size.
21:23 - SL types of wind turbines, or FT types (depends on the manufacturer), the one that is from medium to large size wind turbine for home. Those are good, with the foldable tail feature.
27:50 - short recap
29:55 - showing the calculator tool and too to evaluate potential power losses to help you with your decision

Now about the wind turbines themselves:

1. tiny S3 - I recommend it only as a model, or as a toy, or for fun, or to play around and learn how in general it all works. just the example: https://s.click.aliexpress.com/e/_DeG...
those are generally with 1.1-1.3 m diameter wind wheel, so quite a little power is what they can output. I will claim them to be 100-150 watts wind turbines realistically.

2. Small M3 or SM3 wind turbine, which can be claimed as 250-350 watts wind turbine.
Go for the one specifically with 1.65-1.68 m wind wheel dia.

3. Slightly bigger M-series, SM-5, SM-6, M5 or M6, or SM-5000 / SM-6000 machines. They have 2.0-2.1 m wind wheel, and can realistically output 600-1000 watts of power. However, I've seen people getting out of them out even enormous 2.3 kW, that's their theoretical peak probably.

4. Nice and sturdy SL type of wind turbines (or FT type on my end, as it depends on the manufacturer). from 2.8 up to 5.4 m diameter wind wheel. These are definitely the production workers. And those are the ones to actually invest in, if you need some real production.

Let me know if there are any other topics to be covered, and I will try my best.
