Wholesale 4 Gauge 20Ft Booster Cables | 600A Heavy Duty Jumper Cables Manufacturer

【Excellent performance and reliable quality】
The booster cable utilizes #4-gauge copper-coated aluminum conductors and high-density PVC insulation, capable of carrying peak currents up to 300 amps. Its extra-long 20-foot cable ensures flexible operation in complex rescue scenarios, while its low-resistance design minimizes voltage loss to industry-leading levels. Precision-processed, the booster cable withstands extreme temperature fluctuations, maintaining stable performance in environments ranging from -40°C to 85°C. It has been tested for 3,000 charge and discharge cycles to ensure long-term reliability.
【Extremely long operating distance of 20 feet】
The booster cable offers an extra-long 20-foot (approximately 6-meter) operating range, providing ample operating space for large vehicles and specialized rescue scenarios. The cable features a four-layer insulation structure: an abrasion- and tear-resistant outer layer, a UV-resistant middle layer, and an inner layer that is heat- and corrosion-resistant. The booster cable's specially reinforced design withstands over 20,000 bend tests, far exceeding industry standards. The weight has been optimized to ensure portability while maintaining performance.
【Safety protection and professional design】
The booster cable is equipped with multiple safety features, including reverse connection protection, overload protection, and short-circuit protection. The thickened PVC insulation has passed a 3000V withstand voltage test, effectively preventing accidental electric shock. The booster cable's clamps are fully encapsulated with rubber and feature a serrated design for a secure connection with the battery terminals. Red and black color schemes distinguish the positive and negative poles, and an LED indicator displays the connection status in real time, significantly reducing the risk of operational errors.
【Customized packaging and services】
Boost cables offer customized packaging options, tailored to your needs. They come packaged in high-strength blister packaging with strategically designed compartments to securely store cables and accessories. Customization options include brand logo printing and color matching to meet the individual needs of each user. The manufacturer offers a professional design team to ensure the packaging is both aesthetically pleasing and practical.
【Multi-functional application scenarios】
The booster cable is suitable for a wide range of vehicles, including cars, SUVs, and heavy trucks. It can also provide jump-start functionality for equipment like lawn mowers and ATVs. Equipped with intelligent voltage detection, it automatically identifies the voltage requirements of the equipment. Optimized for high-current transmission, the booster cable excels when starting large diesel engines. Detailed operating instructions are included in the included multilingual user manual.
【Military-grade materials and processes】
The booster cables utilize military-grade copper-plated aluminum conductors with a conductivity of up to 98%. The special PVC outer sheath is UL94V-0 flame-retardant certified and withstands extreme temperature fluctuations. All metal components are nickel-plated for rust resistance, ensuring long-term corrosion resistance. They have also passed salt spray and vibration tests, ensuring they can withstand a variety of harsh operating environments.
【Professional Certification and Quality Assurance】
The booster cables are certified by China Compulsory Certification (CCC), the European Union's CE certification, and the United States' UL certification. Each product undergoes 25 rigorous tests, including load testing, insulation withstand voltage testing, and environmental adaptability testing. The booster cables come with an extended five-year warranty, and a 24-hour customer service hotline ensures prompt resolution of any issues.
【Environmental protection concept and sustainable development】
The booster cables are manufactured from recyclable materials and comply with RoHS regulations. At the end of their lifespan, 90% of the materials are recyclable. The booster cable packaging uses recycled materials to minimize environmental impact. The intelligent energy-saving design keeps standby power consumption below 1W, ensuring environmental friendliness.
