Will this Ebay Car Adaptor Work???

**mattsmith999** · 12-30-2003, 04:45 PM

Right here goes,

as with everyone else here the powering of the carputer seems to be the most tricky bit! I have a cubid case with the built in dc psu. I want a nice and easy way to power the machine with cutting it up so that I update it in the house nice and easily. So the best solution for me would be a dc-dc car adaptor. The question is will this one do??

Original AC Adaptor Specs

DC Output = 12v -- 4.58a

Ebay Car DC Adaptor Specs

15v -- 3.5a

--------------------------------

I know what you are thinking!! The voltage and amps are completly different. But would it do the job and if so what would the damage be?? I really want this solution because it is so easy to connect up but i cant find the perfect car adaptor.

Thanks in advance!!

There is no way in hell you would catch me putting 15V into my 12V power supply! It would probably be better wiring directly to the battery.

I'm guessing you have a Morex DC PSU (long and slim), with the ILAN AC brick?

I have that setup, and I have the PSU wired directly into the battery, and it has been fine for the past couple of months. No guarantees it will also be fine in your car, and no guarantees that it will work at all, try it at your own risk.

ok, will this do??

Maxtor 7200rpm or Seagate Barracuda IV, both 40GB, currently the Seagate, which is borrowed from work as I needed the Maxtor elsewhere

It just doesn't have enough juice to keep the hard drive spinning or spin it up when the engine is off, but with it on, it's fine

I would much prefer to wire it directly to the battery with it's 11-13.8V (ish) input than give it a constant 15V input

Forget my last post.

I have found a car adaptor that will do 12v @ 5a (max). Will that do the job? My original is 12v 4.68a, will this car adaptor do the job??

Thanks!!

This should work fine. Allways use the same voltages as the manufacturers supplied power supply and recommendations. Matching voltages is very important and never use less than specified amps. This is a good rule of thumb and actually a rule that should not be broken if you like the equipment you are using.
