Product Description

This Inverter has been designed with pure sine wave to produce the same AV frequency produced on the grid, making it more reliable than traditional inverters, without any fluctuation in power or performance. Operates from a 12V DC power supply found in cars, caravans, boats and commercials. High performance outlet eliminates electrical interference, reducing noise levels during use.
