Ok guys here is my situation.... I have a laptop that is currently running off of an inverter. I also have another device that is 12v, but I would like it to turn on about 2 mins after the laptop powers on. Upon looking at the startup/shutdown controllers in the store I think I have settled on the CarPC 2.5 EZ or the Pro. What I was wondering is the difference between the EZ and the PRO and also I was wondering if this type of senario can be accomplished with that controller?
