How Your Cobra Power Inverter Works

The Cobra Power Inverter is an electronic prod-
uct that has been designed and built to take low
voltage DC (Direct Current) power from your
automobile or other low voltage power supplies
and CONVERT it to standard 115 Volt AC
(Alternating Current) power like the current you
have in your home. This conversion process
thereby allows you to use many of your house-
hold appliances and electronic products in auto-
mobiles, RVs, boats, tractors, trucks and virtually
anywhere else.
