im assuming a dedicated laptop power adapter is better than using an inverter and laptop power adapter when tuning to minimize the wideband offset?

am im correct or it doesnt make that big of a difference?

 

I receive intermittent power pulses from inverters.... I don't like them.

Power output is crucial.

 

I never observed any adverse effects when using my inverter but direct DC power should be better (on paper at least).

 

I have noticed unless like 500watts my dinosaur old reliable tough book and latitude get pulses from the inverters.

 

The Dell laptop I use for tuning has an express charge option. When I disabled that in the BIOS it stopped pulsing.

 

I've got a little inverter that plugs into the aux power. Its never been powerful enough to keep the laptop charged. I think I got it at best buy.

Back when I was tuning a lot, I considered going with something more powerful but I've got no use for something like that now that I've stopped.

 

You shouldn't need more than 60 watts to maintain power, which theoretically doesn't affect your offsets more than your stereo would. BUT cheap inverters WILL pulse simply because they're generating a sine wave and they don't have a capacitive filter. I would definitely recommend a DC power source for a laptop unless you paid $200 for your inverter.

 

We have seen inverters damage K-Pros and s300s as the voltage spikes can damage the various components on them. It is best to just have a good battery, or plug into a proper AC access point outside the vehicle.

 

its an hp laptop and original power supply is 18.5 volts 3.5 amps and 65watts
i cant really plug it in when im driving the car around.
found this on newegg
http://www.newegg.com/Product/Produc...9SIA35P14M2868
i think that should work perfect

 

do you guys recommend one of those voltage stabilizers or maybe a simple car audio capacitor when using inverter or any kind of power draining acessory?

 

Get a working battery instead for the laptop instead. You will save yourself money and headaches.

 

not the advice im looking for I need a power supply already have a good battery

it lasts for an hour. when connected to the demon

 

That one you found on NewEgg will work and shouldn't cause any tuning problems for you. But it really is better just to get an extended life battery.

 

I did on my last top it sucked as bad as the regular one even though it was HP brand new battery it lasted maybe 40 minutes longer than original I have an older laptop hp g62 not very big on battery life Ill just disconnect it when im logging and have it charging while taking long trips
I have the laptop with me all the time so im adjusthing it as I drive around so I don't waste gas

 

update:

got the inverter.
car is running at 13.9-14.0v at idle mostly with it unplugged it runs at 14.1v not too bad

 

I have always had an inverter. I have had a small tv and a game system and a laptop running all at the same time without a problem while at idle.
