Pure Sine Wave Power Inverter 12V to 220V AC — 1000W Continuous, 2200W Peak, USB 5V 2.1A

Compact, high-performance pure sine wave inverter for 12V systems delivering 220V AC output — 1000W continuous power with 2200W peak capability and a USB port (5V 2.1A). The housing is made from aluminum alloy, keeping weight low while providing excellent thermal conductivity to quickly dissipate heat and maintain reliable long-term operation. The inverter produces a true pure sine wave with intelligent filtering to prevent interference and protect connected appliances. Electrical conversion is optimized via the shortest high-current path to reduce current loss and raise conversion efficiency; overall conversion efficiency reaches up to 95%, with operating efficiency ranging from 80% to 95% and low self-consumption to extend battery life. Thermal design uses centralized dual air ducts (left and right) for even cooling, lowering MOS tube temperature. The product replaces older multi-transformer-series, single-duct designs with a single transformer using vertical multi-layer copper ring superposition winding to cut copper and magnetic losses, reduce heat, and boost efficiency. For safety and reliability, the inverter implements double current detection at both front and rear stages plus multiple protection mechanisms so a single component failure will not damage the power source or connected loads.
