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.

AC to DC
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.
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.
No
Battery Cables Included

This units is great!! I highly recomend it. I use to have a lightning audio amp and stereo with it and it power it with no problems at all, but now that i got my gm-5300t pioneer amp i use a battery to power the system. Even with the 12 volt battery works great!! :D I highly recomend this power supply.

Bigger Than PS12

July 6, 2010

I got this model because the PS12KX were clipping on me when I ran a 1M Candlepower spotlight off it. This unit is bigger and will not clip. I wish they made this with a cigarette lighter plug, but maybe they can't with this size.
