Made of carefully selected high-quality raw materials, this high-capacity portable power supply is a long-lasting energy storage device designed for outdoor activities, long-distance travel, household standby and power emergencies. All materials comply with strict safety, heat resistance and energy storage standards. Adopting premium raw materials instead of inferior recycled accessories, every component including cells, shells, protective rubber and internal wiring has passed multi-layer detection. With superior materials, it features higher energy density, better thermal stability and longer service life than ordinary power banks. The shell is made of high-strength flame-retardant ABS composite material with thickened compression-resistant plates, featuring great toughness, insulation and flame retardancy to avoid potential safety hazards under high temperature.

　　The core adopts high-density lithium battery cells made of brand-new raw materials, delivering higher energy density, stronger power storage and more stable discharge performance. Wrapped with high-temperature resistant insulating film, the cells are protected from high temperature and current interference. Eco-friendly flame-retardant thermal cotton is filled inside to isolate heat diffusion and maintain a constant temperature during high-load operation. The high-purity thickened red copper conductive sheets reduce resistance and heat generation, improving energy conversion efficiency and minimizing power loss.

　　The internal thickened high-temperature resistant silicone wires are tear-resistant and aging-resistant for frequent use. The circuit board adopts industrial-grade fireproof substrate with imported intelligent resistors and capacitors for precise current and voltage control. Reinforced alloy ports are corrosion-resistant and anti-oxidation. With carefully selected premium materials, this lightweight power supply realizes large-capacity energy storage and comprehensive safety protection. Suitable for camping, self-driving and emergency use, it is a stable and high-quality energy storage product with lasting battery life.
