12V 1.5A Power

My monitor's ac/dc adaptor says it puts out 1.5A at 12V, what is the best way to power it without powering it by the computer. I figure it will be some sort of regulator but do not know what kind. Thanks

what brand/model monitor are you using?

and what will you be using to power your carputer?

I bought it off ebay, i dont know the brand, my carputer is a laptop that will be powered by its auto cable, wired to a cigarrette outlet controled by a relay set on the acc line. I just want something separate from the connection of the laptop because they will be very far away. What can i use to keep the dc at 12 V and 1.5 A

you could just buy a dc-dc regulator. look in the mp3car store. your sure to find one. Of the two values you mentioned above, a few things you need to know. If something requires 12 Volts, you ensure the regulator is giving out 12 volts. If it requires 1.5 amps, you make sure the regulator you are using gives a minimum of 1.5 amps. anything more is fine.

I dont risk damaging it by using more than that amount of power?

You will kill the regulator if it cannot provide at least 1.5A. It doesn't do damage the other way around (as long as the Volts are in the ~12V range and depending on how far the manufacturer lets you go below or above 12V)

Where could i get this regulator relatively inexpensively, the ones in the mp3car store dont really seem to be what i want.
