Model:H2.7-500w
As hummer is the smallest bird in the world,H2.7-500w is just 5kg.Due to the light weight,Hummer wind turbine can produce more power than traditional generator.
Meanwhile,Hummer wind turbine introduces seven patented technologies,and two of them are international.With the advanced technology and special material,Hummer wind turbine is "small size,light weight,stable operation and high output efficiency".

Hummer H2.7-500w is well used in housing.Its maximum output power is 1000w,so it can provide sufficient power for daily electricity usage.
