How Your Cobra

®

Power Inverter Works

The Cobra

®

Power Inverter is an electronic product 

that has been designed and built to take low voltage 
DC (Direct Current) power from your automobile by 
simply connecting the power inverter to the cigarette
lighter socket (or connecting directly to 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 household appliances and electronic
products in automobiles, RVs, boats, tractors, trucks and
virtually anywhere else.
