Progressive Dynamics

<h3>About Progressive Dynamics</h3><p>Since its founding in Marshall, Michigan in 1964, <strong>Progressive Dynamics, Inc. (PDI)</strong> 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.</p><p>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.</p><h3>Inteli-Power and the Charge Wizard Advantage</h3><p>At the heart of Progressive Dynamics&apos; product lineup is the flagship <strong>Inteli-Power</strong> converter/charger platform, best known for its patented <strong>Charge Wizard</strong> 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.</p><p>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&apos;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.</p><h3>A Full Line of Electrical Power Products</h3><p>Progressive Dynamics manufactures products across several interconnected electrical categories.
