Your going to get more daily power by spending the money on a small solar panel assuming you have a controller already.
Thought I would get a little more than 3 to 5A at the coast.
As the manual says, double the wind speed and your output goes up 8X. To put it another way, Lose wind speed and the output goes down by a factor of 8.
I am a heavy electrical user. 20 hrs/day. If I were charging my RV house batteries, it should work fine.
Now the good - It is FUN - I now can't wait for the wind..
