Seven layer intelligent protection: built-in original intelligent microprocessor chip imported from America. Effectively control overload and heat, make product performance more stable and safe, effectively protect equipment and battery life. Overcharge protection, overload protection, over current protection, short circuit protection, under voltage protection, over voltage protection, over temperature protection Synchronous rectifier technology: significantly reduces rectifier losses at the output of the switching power supply, improving the conversion rate and reducing the current itself to generate heat. Aluminium alloy housing: aluminium alloy housing design, which is safer than conventional plastic housing, has better heat dissipation effect and more stable performance. International Oxygen Free Copper Core Wire: For input and output connectors, 99.99% oxygen-free copper core wire is used, lower resistance and excellent conductivity. Low heat, low carbon and more energy saving. Fully moulded waterproof design: adopt quality imported organic silicone encapsulation technology of high thermal conductivity, and the interior is completely encapsulated with heat-conducting epoxy resin. Shockproof, waterproof, dustproof, moisture-proof and other functions, protection class IP67. Good compatibility and wide application: suitable for small cars, vehicle recorders, navigation devices, mobile phones, MP3, MP4 and other electronic devices with a power of less than 15W, compatible with more than 95% of common electronic products
