General Features

Type of Inverter
This is the way in which the power inverter will convert the power.

AC to DC: Converts common household AC power to DC Power.

DC to AC: Converts DC power to the common household AC power. Often times these converters can be plugged into the vehicles cigarette lighter.

DC to AC
Maximum Power Output
This is the maximum amount of power that the unit will produce at a given time. Usually this is not the amount of power that is continuously being produced.
800 watts
Continuous Power Output
This is the average amount of power that the unit will produce. If you have specific needs, it is more effective to consider the RMS power output rather than the max power output. Continuous power output is also referred to as a RMS power rating.
400 watts
Sine Wave
A true sine wave inverter will convert the power produced by your vehicle in a true sine wave. This allows for a cleaner power output with less distortion and will allow larger items like appliances to run cooler and quieter. A modified since wave inverter will not convert the power from your car and are typically only suited for smaller items such as fans or lights. If you're planning on hooking up items such as laptops/computers, game consoles or appliances, you want to use a true sine wave inverter.
Number of Power Outlets
This is the total number of outlets that the power inverter, power strip, or other power device has.
USB Port
This means that the item has a USB port. The port can be used to provide the unit with updates or to transfer data on to it.
Fan Cooled
A great feature to have if a power inverter generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the inverter from overheating (burning).
Low Battery Shutdown
When the voltage in the vehicle drops below a certain point, the inverter will automatically shut itself off so prevent the vehicle battery from dying.
Rack Mountable
Some units can be mounted to a rack for organization and convenience.
Battery Cables Included
Battery cables included means that the unit comes with battery cables and clips to connect the unit to the vehicle's battery.

great for roadtrips!

August 11, 2008

Been using it for several months, just an awesome little thing, took this with me from miami to new york, had it plugged up the whole time to my cellphone and laptop, with no problems, and occasionally unplugging one to charge my camera. Have always been a fan of cobra, and this power inverter doesn't disappoint.
