Goce from mp3Car will walk you through the steps necessary to power your laptop using only the p2140 and the wire your laptop power adapter came with.
-For this project you need the following materials:
-p2140 and 8pin molex output harness
-Wire strippers 14-22 gauge
-Shrink tubing and heat shrink tubing gun OR electrical tape
-Solder gun and non leaded solder
-laptop and its power brick
-knife or scissors
The basic procedure here is to cut and strip the laptop power brick, while NOT cutting the multi-strand wires right beneath the black plastic. Then soldering the positive wire of the primary output from the p2140 to positive end of the now cut power brick cord. And then the same for the negative.
In the next video we will show you how to test the polarity using continuity and then actually test turing on the laptop using only the power from the p2140 (through the bench battery of course)

The Chinese manufacturer Bluestar has been making double din all in one units for a few years now. Online carPC retailers digitalww and hipepc have stocked blue star's products in the past but those retailers have now closed up shop.
Mp3car expects to test samples within the next few months to see if this something mp3Car will offer in the hobbyist marketplace(mp3car store). So far so good!
