Purkeys BOSS Dump Trailer Charging System – Charge While Driving

Unlike plug-in chargers, the Purkeys BOSS system charges your dump trailer battery while you’re towing. It connects to your truck’s 7-way trailer harness and directs power to the trailer battery, keeping it topped off during the drive. This is a game-changer if you’re making multiple trips and need the battery ready for each dump cycle.

The system charges faster than standard 7-way circuits, so even short drives can add meaningful charge. It’s purpose-built for dump trailers, so installation is straightforward if you already have a 7-pin connector. The downside is that it only works when the truck is running, and it doesn’t provide a standalone charging option when the trailer is parked.

View all product features

• Connects with a 7-way trailer harness
• Charges trailer batteries while driving
• Charges faster than standard charging systems
• Maintains batteries at a high state of charge
• Includes at-a-glance indicator light

Buyer’s Guide: What to Consider

Choosing the right battery charger for your dump trailer can feel overwhelming with so many options. The key factors depend on how you use your trailer—how often, where you park, and what battery type you have. Below are the most important considerations to help you narrow down the choice.

• Charging Amp Rating: The amp rating determines how fast your battery will charge. For a typical dump trailer battery (75-100Ah), a 10A charger is a good balance of speed and safety. Lower amps (2-5A) are better for maintenance, while higher amps (10A+) suit heavy use.
• Power Source: AC, DC, or Solar: Choose based on where you park your trailer. AC chargers (120V) plug into shore power—great for barns or campsites. DC chargers like the Purkeys BOSS charge while towing via the 7-way harness. Solar chargers are ideal for long-term outdoor storage without wiring.
• Smart Charging vs. Basic: Smart chargers use multi-stage algorithms (bulk, absorption, float) to prevent overcharging and extend battery life. Basic chargers are cheaper but require manual monitoring. For a dump trailer you use regularly, a smart charger is worth the investment.
• Weather Resistance and Durability: Dump trailers operate outdoors, so your charger must withstand rain, dust, and vibration. Look for weatherproof covers, sealed housings, and corrosion-resistant materials. Aluminum enclosures and flip-up covers are common in rugged models.
• Battery Compatibility: Ensure the charger supports your battery type: flooded lead-acid, AGM, gel, or lithium (LiFePO4). Some chargers are universal, while others are designed for specific chemistries. Using the wrong charger can damage the battery or reduce its life.
• Mounting Options: Onboard chargers are mounted directly to the trailer or tool box, saving space and keeping the charger protected. Some models are panel-mount with a flush outlet, while others are portable. Consider your trailer's layout and whether you need a permanent installation.
• Multi-Bank Capability: If your dump trailer has two batteries (e.g., one for hydraulic lift and one for lights/accessories), a multi-bank charger allows independent charging of each battery. This ensures both batteries are maintained without interference.

Conclusion

Your dump trailer’s battery is its lifeline, and a reliable charger ensures you’re never caught with a dead battery when you need to work. From simple AC panel mounts to solar trickle chargers and dual-bank systems, the best choice depends on your specific setup and usage habits.

For most users, a 10A smart charger like the Aituzero or Primary Mover offers the best combination of speed, safety, and convenience. If you often tow long distances, the Purkeys BOSS system is a game-changer. For those who park outdoors, solar options like the SUNER POWER or PolyEnergy provide hassle-free maintenance. Whatever you choose, match the charger to your battery type and mounting preferences, and you’ll keep your dump trailer ready to work.
