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

Compact, high-efficiency pure sine wave inverter that converts a 12V source to a clean 220V output (1000W continuous, 2200W peak) and includes a USB port (5V 2.1A). Designed for reliable long-term operation with low self-consumption to preserve battery life. Key construction and cooling features: - Aluminum alloy shell: lightweight with excellent thermal conductivity to quickly draw heat away from internal components so prolonged use does not degrade performance. - Advanced cooling layout: centralized double air duct (left and right) provides uniform heat dissipation, lowering MOS tube temperatures and boosting conversion efficiency. - Transformer innovation: replaces older multi-transformer-in-series, single-air-duct designs with a single transformer using vertical, multi-layer copper-ring superposition winding to cut copper and magnetic losses, reduce heat generation, and improve overall efficiency. Performance and protection: - Pure sine wave output with intelligent filtering to prevent interference and protect connected electrical devices. - Extremely efficient conversion—working efficiency ranges from 80% to 95%, with peak conversion efficiency up to 95%—and a short, high-current conversion path that minimizes current loss. - Dual-stage current sensing (front and rear) plus multiple protection mechanisms deliver stable, safe operation and help prevent damage to both the power source and connected loads in the event of a single component failure.
