This waterproof outdoor power supply adopts high-grade industrial raw materials and a graded material selection system. Every component including cells, shell materials, sealing accessories and circuit substrates uses high-standard industrial raw materials. Developed for humid, rainy and harsh outdoor conditions, the product adopts Grade A original lithium cells without recycled materials. Through layered screening and internal resistance matching, the cells feature stable chemical properties, low attenuation and strong impact resistance, complying with power battery manufacturing standards to ensure long service life and stable discharge.

　　The shell is made of imported modified PC+ABS composite material with military-grade flame retardant and weather resistance. Without recycled impurities, the raw material delivers high hardness, UV resistance and anti-aging performance. Food-grade silicone and high-density waterproof foam are applied for permanent sealing. Industrial waterproof glue prevents moisture penetration. The circuit board adopts thickened copper foil and high-precision glass fiber substrate with strong corrosion resistance. Water-resistant rubber gaskets at interfaces further enhance waterproof performance against rain and dust.

　　Internal pure copper wiring with high-temperature insulation reduces conductive loss and enhances durability. All raw materials pass strict incoming inspections and weather resistance tests to eliminate inferior accessories. Equipped with multi-circuit protection modules, the power supply ensures safety in humid environments. The compact structural design and anti-slip surface improve portability. With Grade A lithium cells, military-grade shell raw materials, high-standard waterproof accessories and rigorous material inspection, this waterproof outdoor power supply adapts to rainy, coastal and humid working conditions, serving as an industrial-grade energy storage product with premium raw material quality and excellent weather resistance.
