12V to 220V Pure Sine Wave Inverter — 2200W Peak, 1000W Continuous, USB Charging & LED Indicators, Stable and Safe Output

Compact 12V to 220V pure sine wave inverter delivering a peak output of 2200W and continuous power of 1000W. The design uses the shortest current path to cut current loss and boost conversion efficiency. Cooling is handled by a centralized dual-air-duct layout (left and right) for even heat dissipation and lower MOS tube temperatures. The previous single-air-duct, multi-group-in-series approach has been replaced by a single transformer with vertical multi-layer copper-ring superposition winding to reduce copper and magnetic losses, lower heat generation, and raise efficiency. Operating efficiency ranges from 80% to 90% (with conversion efficiency up to 90%). Front- and rear-stage dual current detection plus multiple protective circuits provide stable, reliable operation and prevent a single electronic component failure from damaging the power source or connected loads. The aluminum-alloy shell is lightweight with excellent thermal conductivity to rapidly cool components for sustained use. Pure sine wave output with intelligent filtering prevents interference and protects appliances; low internal power consumption helps extend battery life. Includes USB charging and LED indicators for convenient monitoring.
