My Idea for power source

chopperman · 02-21-2009, 08:21 AM

Going go be using a laptop in the Z and I will need it to be portable so I can tune the car. This is my idea to power it. I was going to cut off the AC to DC converter and run it straight to a 12v power source that is on when the car is running. Then the other end will just plug into the laptop and I would be able to move the laptop in and out of the space easily.

I would have it go into hibernation when the power is shut off to save the battery. What do you guys think? Good idea? Is there an easier way?

There is no easier way than how you described. However, the cars electrical system can vary wildly from 9-16+ volts depending on conditions, i.e. cranking the engine, high-speed driving, load of other accessories, etc. This may be harmful to your laptop.

I just wired a Kensington DC-DC adaptor to my car's 12V line, using a relay that is connected to the ignition switch, allowing me to control on/off power to the laptop.
