That’s a southwest
wind power air-x or air-breeze.
It’s still 12 volt even with a 17 volt output. You need higher voltage to actually charge
batteries.
This is either 400 watts or 200 Watts.
Judging by the shape of the blades, I’ll guess it’s an Air-X 400 watt unit.
On edit. It looks like primus has purchased the product line.
