DC AC Power Inverters are pretty simple devices, they convert DC or Direct Current into AC or Alternating Current. DC is the voltage you often find in your car. AC volatage is most often found in your home.
A good power inverter has several parts too look for.
1: Power Inverter Input Connections:
Notice these are heavy duty connections. DC wiring is often heavier because of the lower voltages. Always use the recommended wire. You also see the chassis ground connection found on some power inverters in this picture.
2: Power Inverter Output Connection or Outlet:
The left side of the picture includes a GFCI AC power outlet.
3: Some sort of display or status light.
The right side of the picture includes the display for voltage and wattage. It also has an ON/OFF switch.
