Our Thanks to You

Introduction

Thank you for purchasing the Cobra CPI 475

inverter. Properly used, this Cobra product will

give you many years of reliable service.
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 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 household appliances and electronic
products in automobiles, RVs, boats, tractors, trucks and
virtually anywhere else.
