Review on Car inverter to cigarette lighter socket 12v/24v up to 220v (black) by Mateusz Rybarczyk ᠌

Weird device. The output is definitely not a sinusoid and not 220V, but it works. A separate switch on the side turns on / off only the large socket, the screen with voltage and the backlight. USB ports and cigarette lighter socket always work. Due to unusual output parameters, not all devices can work. Pros below: Fits in a cup holder. Shows the voltage in the input network (on the car battery). Cons below: The output is 110V DC (!) current. However, the power supply from the laptop works (the laptop is charging).
