🔌 Product Description: Road Charger with 7-Way Trailer Plug & 33-Watt Solar Panel

Keep Your Dump Trailer Battery Charged — Anytime, Anywhere

The Primary Mover Road Charger is an all-in-one smart charging solution designed specifically for dump trailers and auxiliary battery systems. This system not only boosts charge while you're driving using the 7-way trailer plug, but it also includes a powerful 33-watt solar panel to keep your battery maintained when your trailer is parked.

✅ Key Features:

  • Smart Road Charging (20–25 Amps): Unlike basic parallel connections, this charger intelligently draws power from your towing vehicle’s alternator using a 7-way plug to output up to 25 amps of charge.

  • Enhances Alternator Output: By creating a demand load on the vehicle's starting battery, the Road Charger triggers modern smart alternators to increase their output — allowing efficient and consistent charging of the trailer battery.

  • Integrated 33-Watt Solar Panel: Powerful enough to provide a true trickle charge, this panel keeps your trailer battery maintained even when it's parked for extended periods.

  • Plug-and-Play Simplicity: Designed for easy installation with included 9-ft wire whip, Anderson plug connection, and a pass-through 7-way male-to-female adapter.

  • Smart Float Mode: Automatically reduces current when the battery is full, extending battery life and preventing overcharging.

  • Faster Than Shore Power: Charges faster than most onboard 120V AC trailer chargers, which typically output just 8–18 amps.

📦 What’s Included:

  • 33-Watt High-Efficiency Solar Panel

  • Road Charger Module (Smart Charging Controller)

  • 9-ft Wire Whip (Connects to 7-way harness)

  • Anderson Plug System

  • Specialty 7-Way Male-to-Female Pass-Through Plug

  • Battery Connection Cables

Whether you're hauling gravel on the job site or parked in a field for months, the Road Charger ensures your trailer battery stays ready for action.
