12V to 220V Pure Sine Wave Inverter — 2200W Peak / 1000W Continuous Voltage Converter with USB Charging & LED

Compact 12V to 220V pure sine wave inverter delivering 2200W peak and 1000W continuous power with built-in USB charging and LED indicators. Designed for reliable long-term use, it provides clean, filtered AC output that won’t interfere with sensitive electronics while keeping battery drain low. Key design highlights: - Power and ports: 12V DC input converting to stable 220V AC output; 2200W surge capacity and 1000W continuous output. Includes USB charging and an LED status indicator. - Advanced thermal and transformer engineering: replaces older multi-transformer series layouts with a single transformer using vertical, multi-layer copper-ring superposition winding. This cuts copper and magnetic losses and lowers heat generation. Cooling is handled by a centralized double air-duct system (left and right) for even heat dissipation and reduced MOS tube temperature. - Improved efficiency: design changes raise working efficiency from 80% to 90%, with peak conversion efficiency up to 90%. - Robust protection: dual-stage (front and rear) current detection and multiple protection mechanisms prevent a single component failure from damaging the power source or attached loads. - Durable housing: lightweight aluminum-alloy shell provides excellent thermal conductivity to dissipate heat quickly, allowing uninterrupted long-term operation. Pure sine wave output plus intelligent filtering ensures safe, interference-free operation with household and sensitive equipment. Low self-consumption further extends connected battery runtime.
