12V to 220V Pure Sine Wave Power Inverter 2200W Peak / 1000W Continuous with USB Charging & LED, High Power

Compact 12V-to-220V pure sine wave inverter delivering 2200W peak power and 1000W continuous output, equipped with USB charging and LED indication. The design minimizes conduction length for high-current paths to cut current loss and boost conversion efficiency. Cooling is handled by a centralized double air duct (left and right) for even heat dissipation, lowering MOS tube temperature. Instead of the older single-air-duct, multi-transformer-in-series approach, this unit uses a single transformer vertical multi-layer copper ring superposition winding method to reduce copper loss and magnetic loss, decrease heat generation and raise overall efficiency. Working efficiency from 80% to 90%. Double current detection of the front and rear stages provides multiple layers of protection so a single component failure won't damage the inverter, the battery supply or connected loads. The housing is an aluminum alloy shell — lightweight with excellent thermal conductivity to rapidly dissipate heat and support long-term operation. Pure sine wave output and intelligent filtering prevent interference and safeguard sensitive electrical appliances. High conversion efficiency (up to 90%) and low internal power consumption help extend battery runtime.
