The Air series from Southwest Windpower, are by far the world’s best-selling wind generators with over 135,000 units sold worldwide. The third generation Air-X has an incredible 400w output squeezed into a small lightweight body with built in charge controller and simplified installation.
Less than 6 kilos - The Air-X weighs less than 6 kilos, compared to as much as 20 kilos with other 400w models. Weight is important as it simplifies installation by requiring less support and can be mounted on a pole on the stern or attached to an arch.
The Sailors Choice - The Air-X marine has a powder coated marine grade aluminium body for maximum corrosion resistance and has been a favorite among sailors since its introduction, probably the most widely used generator on sailing boats.
Optimized for higher Wind Speeds - At the factory setting of 14.1 volts (12 volt model) adjustable for different battery types, the Air-X can produce over 25 amps with a little over 20 knots of apparent wind, conditions which when sailing upwind are not uncommon. For constant high wind areas such as the trade wind regions we can expect 128 - 260 Ah/day with wind speeds from 15 - 20 Knots.
Built-in Charge Regulator - The Air-X Marine features a sophisticated built in charge regulator allowing connection directly to the batteries (circuit breaker or fuse is recommended) with a red LED indication light on the bottom of the unit. The light turns on when the unit is charging and flashes when the internal regulator senses that the batteries are charged.
For an independent comparison of most wind generators currently available, see the following link from Skipper. Tests performed on boats in the Caribbean.

Using a 13 volts conversion rate, we can compare output based on average wind.
6 knots - 230 Ah/month - 7.6 Ah/day
10 knots - 1150 Ah/month - 38 Ah/day
15 knots - 3840 Ah/month - 128 Ah/day
20 knots - 7800 Ah/month - 260 Ah/day
