The Jonfa 4000W 12V power inverter is a high-capacity DC-to-AC converter designed to transform 12-volt battery power into standard household electricity (110V–120V AC). It delivers up to 4000 watts of continuous power with a surge capability (typically up to 8000W) to handle appliances with high startup demands
Built for off-grid and mobile use, this inverter is commonly used in RVs, trucks, solar systems, and emergency backup setups, allowing you to run devices such as microwaves, power tools, TVs, and small air conditioners directly from a battery system
