a rookie with only three post and all of them on this tread...........? sure looks like spam to me

 

I don't think so at all. The guy took the time out to try and help others with his first post and then a LOT of time with his last one. I'm looking into it, because I have some of the problems he's talking about. Thank you freedomrider1.

 

I have a 2500 watt Tripp Lite inverter and have never experienced EMF / RFI issues. Large inverters like mine stay connected and on 24 / 7 / 365, so what good would buying a DC / DC notebook adapter do in my case? Besides anybody who does have interference issues, can simply add some EMF / RFI shielding and STOP the interference.

 

Why you will need a extra inverter to run a laptop.... it has its own batteries and power consumption is very low!!!!

 

Laptop batteries will last a few hours at best. I am gone for days, not hours.

I did have interference with the 1500 watt Xantrex inverter I used to run. I just bought a cheap 400 watt cobra to run my laptop on. Then I only used the big one occasionally to run my microwave. That solved my problem.

 

I've never had any problems with my inverter.

 

I used to have issues with RFI when using an inverter, until I put in a Xantrex IP1012 AL unit. It is an external inverter/charger about the size of a group 31 battery. It can be mounted externally on a frame rail if someone wanted to do that. I had room in my battery box along side of the 4 group 31 batteries and I installed it there. You can even take a pressure washer to the inverter with no negative effect. Since the unit is enclosed, and bolted bolted to the battery box so that it is solidly grounded, it has had virtually zero effect on my CB reception. It is encased in aluminum and I think it kinda acts like a Farraday Cage when it comes to RFI. And when shore power is available, it is a pass thru unit and also will charge the batteries. I managed to get ahold of one of the last of these, since Xantrex discontinued them due to slow sales. True, these units are not the high powered 2500 watt units some may need. They were only a 1000 watt with a 3000 watt surge for 30 seconds. But my power needs are more modest than others, so it was a good choice. It is more than enough to simultaneously run my fridge and other goodies in the truck.

I just checked, and if anyone is interested in one of these, I saw a seller on Ebay that had a few of them, new in the box. Xantrex still has the brochure on these online at their website. They are darn good units that will take a real beating. They were designed for tough marine, construction, and trucking environments and can be placed in engine compartments, external rails, battery boxes, or wherever. They are a little pricey, but when you consider that these units are built like a tank and can handle being exposed to just about any environmental condition, you get what you pay for. And they emit very little, if any, RFI.

 

I bought a laptop with a wind up motor, problem solved

 

LOL. But that would be a possibility, I guess. But, really, one of the small solar power units from places like C. Crane would do the trick in charging up a laptop. There are a quite a few options to get the job done.
