Newmar Power

Newmar Power has provided "Essential City" level reliability to marine electrical systems for over 50 years. Their Phase Three series "Smart" battery chargers are the industry benchmark, featuring three-stage charging (Bulk, Absorption, Float) and marinized internal circuitry for maximum corrosion resistance in the engine room environment. Newmar’s range extends from DC power supplies and converters to galvanic isolators and waterproof power posts, all housed in rugged stainless steel or powder-coated cases.
