Voltage converter from 12V to 220V (3500W)

Voltage converter ERYUAN MX-3500 - from 12V DC to 220V AC voltage (output signal shape - step sine wave) is designed to power household appliances with a power of up to 3500 Watts.
When choosing a voltage converter, you should pay attention to the power of the device that will be used, since the voltage converter is designed for a certain load and if there is insufficient power, it simply will not work or will not arrive. And the sequence of connecting devices should be observed: first, the voltage converter is connected to the cigarette lighter socket or battery terminals (depending on the configuration), then the consumer is connected to the converter socket (in the off state), and only then the converter is turned on, and then the consumer itself.
