396xt DC vs AC adapter in Car

[cgresq192]

If I already have a AC/DC inverter for my car would it be ok to use the supplied AC adapter or would I be better suited to get the DC adapter for the car?

A DC-DC adapter would be best (more efficient and much less space required), but I see no reason why a DC-AC inverter wouldn't work.

Most DC-AC inverters generate RFI....DC-DC converters that use a higher input voltage than the output typically use a passive non-switching circuit without components that generate RFI.

I tried this years ago and there was too much interference from the inverter. Everything worked OK with the DC cigar plug though.

Thanks for all the responses. I will bite the bullet and buy the DC plug

Yes my inverter does generate noise, however it's not too bad on the scanner (unless I have the audio output plugged in to the aux input on the stereo).

As far as efficiency with the inverter, you're taking 12v dc, turning it in to 110v ac (modified sine most likely), then in to the transformer where it's going from 110v ac to 6v dc. With the cigarette adapter your going from 12v dc to 6v dc, simple as that.

I think you will be happy that you did. I find reception can suffer depending on the cirumstances when I plug in the AC adapter.
