Power your RV, camper, marine, or automotive equipment with confidence. The Quake 12-24V 12AWG Pure Copper Cigarette Lighter Extension Cable is a heavy-duty, high-current power cord engineered for demanding vehicle and marine applications. With a genuine 12AWG oxygen-free pure copper core, 20A rated capacity, and built-in fuse protection, this extension cable delivers stable, uninterrupted DC power wherever you need it.

Made in Mainland China.

Genuine 12AWG Pure Copper Wire — 20A Stable Heavy-Duty Performance

Unlike standard 14AWG or 16AWG thin wires, this extension cable uses a high-purity oxygen-free pure copper core with a larger wire diameter. The result: lower resistance, superior conductivity, and the ability to sustain 20A continuous current output without significant heat buildup, voltage drop, or power loss. Ideal for running car chargers, air compressors, vacuum cleaners, power inverters, and other high-draw devices from your 12V or 24V DC vehicle system.

Built-in Fuse — Overload & Short-Circuit Protection

Safety is built in. The integrated fuse provides professional over-current, short-circuit, and overload protection. If the circuit is abnormally overloaded or short-circuited, the fuse instantly cuts power — protecting your vehicle's electrical system, wiring harnesses, and connected devices from damage. Perfect for extended high-power use and outdoor power operations.

12V & 24V Universal Voltage Compatibility

Supports 12V/24V dual-voltage DC power systems, making it universally compatible with cars, motorcycles, SUVs, trucks, engineering vehicles, RVs, campers, yachts, and boats. One cable handles virtually any DC vehicle power extension need on the market today.

Professional RV & Marine-Grade Durability

Specially engineered for RV, camper, and marine boat environments. The outer insulating sheath uses high-grade waterproof, anti-aging, high-temperature, and wear-resistant materials — built to handle damp marine conditions, outdoor UV exposure, and repeated bending without degrading. Far more robust than standard household or automotive extension cords.

Wide Application Scenarios

Compatible with all 12–24V DC vehicles and marine equipment. Use it to extend power for:

  • Car chargers & USB hubs
  • Air compressors & tire inflators
  • Portable vacuum cleaners
  • Power inverters
  • RV & camper daily appliances
  • Yacht & boat power wiring
  • Outdoor mobile power supplies

Frequently Asked Questions

Q: What vehicles is this 12AWG cigarette lighter extension cable compatible with?

A: This cable is compatible with any 12V or 24V DC vehicle, including standard cars, motorcycles, SUVs, trucks, engineering vehicles, RVs, campers, yachts, and marine boats. Its dual-voltage universal design makes it suitable for virtually any DC vehicle power extension scenario.

Q: Why is 12AWG wire better than standard 14AWG or 16AWG extension cords?

A: A 12AWG wire has a larger cross-section diameter, which means lower electrical resistance, less heat generation, and a higher current-carrying capacity. This cable is rated for up to 20A continuous output — significantly more than thinner gauges — making it safe and reliable for high-draw devices like air compressors, inverters, and vacuum cleaners.

Q: What does the built-in fuse protect against?

A: The integrated fuse guards against over-current, short-circuit, and overload conditions. If an abnormal electrical event occurs, the fuse instantly interrupts the circuit to protect your vehicle's wiring harness, connected devices, and the cable itself from damage. It is a critical safety feature for high-power and long-duration use outdoors or on the water.

Q: Is this cable waterproof and suitable for marine or outdoor use?

A: Yes. The outer insulating sheath is manufactured from high-grade waterproof, anti-aging, UV-resistant, and wear-resistant materials, specifically engineered to withstand the damp, corrosive, and sun-exposed conditions found in marine, RV, and outdoor environments.
