About Progressive Dynamics

Since its founding in Marshall, Michigan in 1964, Progressive Dynamics, Inc. (PDI) has built a reputation as one of the most trusted names in power conversion and battery charging technology. What started as a manufacturer of LP gas regulators for the recreational vehicle industry evolved, beginning in 1968, into a focused developer of power converters and intelligent charging systems that RV owners, boaters, and specialty vehicle operators rely on every day.

Every product that leaves Progressive Dynamics is designed, assembled, tested, warranted, and serviced in the United States — a commitment that sets the brand apart in a market increasingly crowded with overseas alternatives. This dedication to domestic manufacturing translates directly into consistent quality, accountability, and a customer service experience that enthusiasts and industry professionals have come to trust across millions of units deployed in the field.

Inteli-Power and the Charge Wizard Advantage

At the heart of Progressive Dynamics' product lineup is the flagship Inteli-Power converter/charger platform, best known for its patented Charge Wizard technology. Rather than charging a battery at a fixed voltage the way conventional converters do, the Charge Wizard uses microprocessor-controlled logic to continuously monitor battery status and automatically cycle through four operating modes: Boost, Normal, Storage, and Equalization. This approach has been shown to extend battery life by two to three times or more compared to traditional single-stage charging — a meaningful advantage for anyone who spends time dry camping, boondocking, or running a boat far from shore power.

The Charge Wizard is protected by U.S. Patent 7,782,002, and the Inteli-Power 9200 Series converters carrying this technology are UL listed for use in both the United States and Canada. Whether you're looking for a standalone converter/charger or an all-in-one power management solution, Progressive Dynamics has a product engineered to fit the job.

A Full Line of Electrical Power Products

Progressive Dynamics manufactures products across several interconnected electrical categories. Their RV battery chargers and converter/chargers form the core of the lineup, covering everything from compact replacement units to high-amperage all-in-one power centers. The brand's inverters and power inverters — including the Inteli-Power 1600 Series pure sine wave models — allow RV and marine users to run sensitive AC electronics cleanly and efficiently from a 12-volt battery bank. Rounding out the electrical ecosystem, PDI's breaker panels and AC/DC power distribution panels provide organized, protected circuit management that integrates seamlessly with their converter and charging hardware.

Whether you're upgrading an aging RV power center, outfitting a new boat, or specifying electrical components for a specialty vehicle build, Progressive Dynamics offers purpose-built, American-made solutions designed to perform reliably for years to come.
