Pure Sine Wave Power Inverter 12V to 220V — 1000W Continuous (2200W Peak) with USB 5V 2.1A — Low No-Load Losses

Durable aluminum-alloy housing provides a lightweight case with excellent thermal conductivity to quickly dissipate heat from components, keeping performance stable during long-term use. The unit includes a 5V 2.1A USB output for charging small devices. Delivers a true pure sine wave output with intelligent filtering to prevent interference and to protect connected appliances. The inverter achieves high conversion efficiency (up to 95%) and low self-consumption, which helps extend battery runtime. Working efficiency ranges from 80% to 95%. Electrical layout minimizes conductor length for high-current conversion, reducing current loss and improving overall efficiency. The design replaces older multi-transformer series layouts with a single transformer using vertical multi-layer copper-ring winding to cut copper and magnetic losses, lower heat generation and boost conversion performance. Cooling uses a centralized dual air-duct system (left and right) to evenly dissipate heat, lowering MOSFET temperatures and further optimizing efficiency. Front-and-rear double current detection and multiple protection circuits ensure stable, reliable operation and prevent damage to either the power source or connected loads if a single component fails.
