I suppose this is as good a place as any to ask whether anyone knows of a particular model of adaptor that will allow my 18V laptop to run off of 12 VDC without creating RFI. A few friends have had R

I can tell you one to avoid: the universal adapter with numerous plugs, the one I bought off Internet is Espow brand... about 20-25 bucks on E-Bay... RFI even with ignition off. I tried the small Tri

Hi Chuck, I know of no commercially available DC-DC boost converters that claim to be quiet and produce the voltage/current you need. We've been using this (http://tinyurl.com/2hv8dz) unit that was d

Using raw auto power seems a little risky to me - if you don't want to fry your laptop when running the starter motor or getting a jump start... OTOH, that's what we do with our ham gear. 73 Martin A

That's why most of us fuse our DC cables - perhaps an intermediate battery or large cap might add to mobile gear longevity? I believe that the internal battery in a laptop, together with a fused cabl

Hey Chuck, I think I have the converter you need. I'll post the info tomorrow. I believe it's made by Lund and is 13vdc in and about 19vdc out. They are used for Panasonic tough book Mobile Data Term

My experience is that my IBM T-series laptops run on a direct connection to the car if it's running. I've tried running them from a 12V battery (not being charged), and the charge regulator inside th

Update: The Thinkpad 380ED (an older model laptop to be sure) was satisfied with a Vbatt source w/o the engine running - diagnostics indicated the battery was in charge mode ... but this particular l

Mike, that's all well and fine, and many of us have had similar lash-ups with gear designed to be driven from such 12V sources ... I remember one such lash-up we had back 'in the days' on board a tur
