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

Compact, high-performance inverter converts 12V DC to 220V AC delivering 1000W continuous power and 2200W peak output, plus a 5V 2.1A USB port for charging small devices. The casing is an aluminum alloy shell — lightweight with excellent thermal conductivity — so component temperatures drop quickly and long-term operation remains stable. Producing a pure sine wave with intelligent filtering, the unit avoids interference and protects sensitive appliances. It achieves high conversion efficiency (up to 95%) and low idle power draw to significantly extend battery runtime; overall working efficiency ranges from 80% to 95%. The design shortens the high-current path to cut current loss and boost conversion performance. Cooling and transformer advances include centralized double air duct left and right uniform heat dissipation to lower MOS tube temperature, and an upgrade from the previous single air duct multiple groups of transformers in series innovation to single transformer vertical multi-layer copper ring superposition winding method — reducing copper loss and magnetic loss, decreasing heat generation and improving efficiency. Safety is reinforced by Double current detection of the front and rear stages and multiple protection measures to ensure stable, efficient operation and prevent damage to the power source or connected loads if a single electronic component fails.
