Designed for high power equipment, the 14AWG heavy duty power cord is made of 99.9% oxygen-free copper conductor, which significantly reduces resistance and voltage loss to ensure efficient operation of 12V/24V systems (e.g. LED lighting arrays, security cameras). The cable body is wrapped with flame retardant PVC jacket, which is tear-resistant, grease-resistant, and resistant to extreme temperature and mechanical stress, making it reliable and durable for industrial scenarios. Nickel-plated DC plug provides ultra-low contact resistance, closely bites the equipment port to avoid loose power outage; 20mm bare copper wire is reserved at the pigtail end, supporting soldering or crimping with terminals to meet the needs of DIY modification for home theater, automotive equipment, photovoltaic systems and other diversified scenarios, specification parameters: Interface: DC 5.5x2.1mm (ID 2.1mm, OD 5.5mm) Wire gauge: 14AWG (cross-sectional area 2.08mm²) Operating Temperature: -20℃ ~ 80℃
