Rutland 504 Windcharger 12v

The Rutland 504 is a super compact turbine that is great for using wind power for trickle charging. You can be sure that when you arrive on board your batteries will be well charged up and ready for your appliances

A completely unique mini Windcharger designed with the weekend yachtsman in mind.
