1、12/24VDC to 220VAC: The car inverter provides a 220V AC socket for continuous DC to AC power output, and converts 12V/24V DC battery power to standard 220V AC. 2、3 AC Sockets and 4 USB Ports: 220V AC power socket is used to charge large devices such as laptops and tablets, and the USB charging port is used to power USB compatible devices, suitable for camping, outdoor needs or driving on the way. 3、6 Protection Functions: Multiple protections, such as under voltage protection, over voltage protection, over temperature protection, overload protection, battery reverse connection protection, and short circuit protection. 4、Cooling Fan: The smart cooling fan will automatically rotate at different speeds according to the power load and temperature. This design helps reduce fan noise. At the same time, high?speed heat dissipation protects the inverter from overheating. 5、Application: It can be directly connected to 12V/24V batteries for emergency, hurricanes, storms, snowstorms, power outages, mobile phones, laptops, lights, digital cameras, breast pumps, power tools and other electronic products. 6、Real Time Voltage Detection: The inverter always protects the battery, with an intelligent voltage detection chip, real?time zero?second feedback of the battery and inverter voltage, and always protects your electricity safety
