vansoet 400w Paek-Clipped Sine Wave: It is a specialized form of sine wave. Its fundamental waveform closely resembles a pure sine wave, exhibiting low total harmonic distortion. Load compatibility is on par with a pure sine wave and far exceeds that of modified sine or square waves. Derived from a pure sine wave, the clipped-sine topology uses active circuitry to limit peak output voltage, protecting connected equipment from overvoltage damage. This peak clipping simultaneously suppresses higher-order harmonics, making the waveform ideal for powering highly sensitive electronic devices. Converts DC power from your car battery to AC power for you to use within its watt range. Plug it into a 12V cigarette lighter socket to provide continuous DC to AC power, 2 AC sockets to operate any 110V device, 1 USB-A port (QC 18W) and 1 USB-C port (PD 30W ) intelligently detects your device and automatically provides the fastest charging speed, up to 2.4 amps per port / 4.2 amps maximum. Isolated Voltage Protects Perfectly for your device from Over-voltage,Under-voltage,Overheat,Overload, Reverse Polarity,Short circuit.it will not drain your battery dry because of an under-voltage protection point.The Inverter does automatically sense overload condition and shuts down AC power when the load exceeds 450W. You will need to power Off/On to reset the overload condition indicated by the Flashing Red.The ON-OFF switch only works for the 3-prong plugs. This is an inverter converting DC from your car battery to AC for whatever you want to use within its Watt range.It can pull power from the battery through the cigarette lighter plug or directly clamp the alligator battery clips onto the car battery.Plug this into 12v cigarette lighter outlet provides continuous DC to AC power with 2 AC outlets operates any 110v device and 2 USB ports which detects your device automatically to deliver its fastest charge speed up to 2.4 amps per port/4.2 amps max CPF Certified Product: It is manufactured in an environmentally friendly factory using green photovoltaic energy throughout the entire production process, practicing the concept of sustainable development and being more environmentally friendly. 400W Pure Sine Wave Car Power Inverter DC 12V to 110V AC Inverter vansoet 400w Paek-Clipped Sine Wave is a specialized form of sine wave.
