PECRON 500W Car Charger DC1242-500

High-Power, Intelligent DC-to-DC Charging for Portable Power Systems

The PECRON 500W Car Charger DC1242-500 is a rugged and efficient DC-to-DC charging solution designed to rapidly charge portable power stations, battery banks, and 12–42 V systems directly from your vehicle’s alternator. Delivering up to 500 W output, it’s perfect for cars, RVs, trucks, boats, and off-grid setups—keeping your energy storage systems charged while you travel. Built for safety, durability, and versatility, it provides professional-grade charging performance for on-the-go power users.

High-Power DC Output
With an impressive 42 V/13 A output, the DC1242-500 provides up to 500 W of charging power, replenishing large battery packs in less than an hour. It efficiently converts your vehicle’s alternator output into clean DC energy suitable for solar-ready batteries and generators.

Wide Input Voltage Range
The charger operates across a 12 V to 30 V input range (up to 50 A max), making it ideal for both standard car systems and heavy-duty truck alternators. This flexibility ensures stable performance regardless of vehicle type.

Adjustable Starting Voltage
A built-in voltage threshold dial allows you to set the minimum vehicle voltage required before charging begins. This smart feature prevents drain on your starter battery—waiting until your alternator stabilizes before outputting power.

Comprehensive Safety Protections
Equipped with short-circuit, over-voltage, under-voltage, and overheating protection, the DC1242-500 safeguards both your vehicle and connected devices. It includes a 100 A inline fuse and active fan cooling for safe, consistent operation under heavy loads.

MC4 Solar Output Compatibility
Designed with standard MC4 connectors, the charger integrates seamlessly with most solar power stations and batteries. Simply connect it to your power station’s solar input port for easy mobile charging—no special adapters needed.

Versatile Applications
The PECRON DC1242-500 is perfect for a wide variety of mobile and off-grid use cases:

• Charge Solar Power Stations on the Road: Recharges up to 500 Wh per drive, up to 4× faster than standard 12 V lighter sockets.

• RV and Van Life Power Support: Keeps portable generators charged while driving.

• Truck and Commercial Power: Ideal for powering tools, electronics, and cab systems.

• Marine and Boat Use: Efficiently charges inverter or house batteries underway.

• Overland and Remote Work: Durable enough for rugged terrain and extended expeditions.

Frequently Asked Questions

Can I plug this directly into a vehicle’s cigarette lighter socket?
No. This charger must be connected using the supplied heavy-duty ring terminals and inline fuse to safely handle the full 50 A current.

Will it drain my car battery if the engine is off?
No. The DC1242-500 should be switched off when the engine isn’t running. Once the engine starts and voltage rises, it automatically begins charging.

What devices can I charge with it?
Any power station or battery bank with a solar input rated up to 42 V, including PECRON E-Series, Bluetti, EcoFlow DELTA, Jackery Explorer, and other compatible systems.

How do I set the voltage threshold?
Use the adjustment dial (gears 0–5) to set the minimum alternator voltage before charging starts. Refer to the included manual for the voltage chart corresponding to each gear level.
