Feature: 1. Overload Protection: Our inverter can do automatic protection, such as overload protection, can achieve 3 times peaking, strong compatibility, compatible with most devices. 2. Heat Dissipation Design: Our pure sine waves inverter has a slotted heat dissipation design, with great texture, strong metal feeling, beautiful and practical. 3. High Sensitivity: The inverter is more sensitive when short circuit occurs, software detects 1S lockout and does not work, compared to analog circuit with hardware protection. 4. Wide Application: The inverter is perfect for travel, camping, boat rides, etc. Can support a variety of resistive loads, such as computers, fans, copiers, heaters, rice cookers, etc. 5. Aluminum Mg Alloy: The inverter is made of thickened aluminum Mg alloy, which is light and durable with excellent thermal conductivity and can extend the service life. Specification: Item Type: Inverter Material: Aluminum Mg Alloy Input Voltage: 12V Power: 3000W Output Waveform: Pure Sine Waves Conversion Efficiency: 90%.
