【Fast & Smart Charging】Features a 3-in-1 design with Type-C and dual USB ports. The built-in smart chip automatically identifies devices, and the USB super port supports 12V/1.5A fast output, while the Type-C PD port enables 5V/3A rapid charging. Fast charging with optimal current. The powerful combination of dual USB ports and a Type-C PD port provides up to 66W of power. PD30W. You can charge your smartphone and tablet simultaneously with peace of mind. Say goodbye to the worry of running out of battery while driving. (Safety design with automatic shutdown in case of overload or short circuit) 【5-Stage Protection Circuit】Equipped with a high-performance main control chip, integrating protection functions against overvoltage, overcurrent, short circuit, overheating, and interference. If a sudden current surge or abnormal temperature (below 60°C at room temperature, within the normal heat dissipation range) occurs, the system activates the protection function and automatically adjusts the temperature within milliseconds. It functions as a faithful guardian to protect your important electronic devices. When the charger surface temperature reaches 60°C, it automatically adjusts the output, continuously monitors abnormal conditions, and activates a protective mechanism like providing fire-resistant armor for the device. (Please avoid use in high temperatures or direct sunlight, as this can reduce charging efficiency) 【Wide Compatibility】The metal contacts support a wide voltage input of 12V/24V, compatible with various vehicles such as passenger cars, SUVs, and trucks. Perfectly adaptable to any vehicle, from small cars to large trucks. The metal flexible contacts securely connect to cigarette lighter sockets of various sizes, preventing loosening even on bumpy roads. The 4-in-1 all-in-one interface (cigarette lighter + Type-C + dual USB) simultaneously meets all needs, such as fast charging for mobile phones, powering tablets, and powering a driving recorder. 4-in-1 Cigarette Socket 【66W Super Fast Charging】 Car charger, car charger, supports PD30W fast charging protocol, LED display with real-time battery voltage monitoring function, Type-C, dual USB, 3-port interface, intelligent current distribution function that can charge simultaneously, supports a wide voltage range of 12V to 24V
