There is a reason the Windtura 750 weighs 25 pounds and many of the "500 to 1500 Watt" Delco PMAs that our competitors sell weigh about 10 pounds.
To produce meaningful amounts of power, you need lots of copper and powerful magnets, and the comparisons below show you just how much bigger the WindyNation PMA is. If you want more than just a paperweight, check out the sturdy and robust Windtura 750! And just look for yourself at how a Delco compares to our PMA.
