PowerMax PM4 100A Power Converter | 110V AC to 12V DC | 4-Stage Smart Battery Charger | RV, Boat & Off-Grid

PowerMax PM4 100A Power Converter — Reliable 12V DC power from 110V AC for RVs, boats, and off‑grid living

When you’re away from shore power, clean, consistent DC power matters. The PowerMax PM4 100A converts standard 110V AC into a robust 12V DC supply, delivering strong current for high-demand devices such as trailer lighting, water pumps, and onboard electronics. In real-world use, you’ll notice lights that stay steady, pumps that start reliably, and electronics that feel responsive rather than dim or glitchy.

Beyond raw power, the PM4 100A is built with smart charging and protective features to help keep your battery system healthy. Its intelligent charging approach includes Bulk, Absorption, and Float phases, and its safety protections guard against reverse polarity, overload, and overheating. This combination supports consistent performance while helping to extend battery life in variable conditions.
