Running a laptop on a 12 volt to 110 volt inverter

17 posts in this topic

Hi, I am wondering if an inverter would have any ill effects on a laptop. I Am thinking about mounting one in my fish house, and wonder how it would do with a laptop. Thanks.

You should be fine. I can see no reason the inverter would harm anything, their power tends to be pretty clean.

While up north a few weekends ago, I ran my laptop off an inverter in the boat so my kids could watch movies while mom and dad got to fish the night bite. Worked excellent! And it didn't hurt the laptop wink

Yes, I do this all the time, there's no problem at all. On a side note though, pay attention to those little sticky tags they put on the cord though. I had the bright idea of charging the batteries for my cordless drill from the inverter. After a while, I noticed the lights on the charger had went out. Lo and behold the tag on the cord said right on it not to run the charger from an inverter. D'oh! Oh well, it only took out the fuse and it was a simple fix, but who woulda guessed?

I do some music and audio recording as a hobby. I frequently take my laptop out in the boat on a nice afternoon with a few friends for some jammin'. Never had a problem.

Thanks for all the quick replies, I think I will get one for my fish house now.

I use it all the times on my truck. Don't need a huge inverter, a 250watts is plenty enough. I also use it just to charge the battery, the battery for camcorder, etc.

We use one all the time in the car. Be sure to get a good one especially one with a fan for cooling as they get pretty warm.

If the inverter outputs the TRUE 60 cycles /second, then you will not hurt your battery. But if the inverter is a cheap one, your battery will have a shortened life. Removing the battery while using a power inverter is usually better.

I use a 400 watt inverter in my van to power my laptop and inkjet printer - business use all day long, for over 4 years now. Works Great!

Most laptop computers can use around 100 watts with cd/dvd drive running plus hard drive running and display active. I recommend getting the inverter at about twice the rating you plan on using. If the inverter runs at less than rated it should last you a good long time.

I have a very small one that fits right in my computer bag. It plugs directly into the cig lighter - the whole thing is self contained. The only drawback is that if the cig ligher is recessed too much, it doesn't fit.

It has a 140W continuous, 175W (max 5 minutes) rating and has a small, nearly silent fan in it.

lets see, we are going from DC to AC to DC.

It's too bad laptops are too sensitive to use the 12 volt car batteries. Laptops use something like 14 volts right? If you had a transformer and a voltage regulator it could be done(?). Of course the inverter is just easier and more available.

Like Rainy River said. The battery in my Dell LT was toast after using about 3 times with the inverter.

That is odd because mine is a Dell and there isn't any problem with the battery life using an inverter.

Our test technicians also use inverters with their computers to do datalogging, etc. and they work fine, afaik.

Mine also is a Dell, and my post above, now over 4 years running from an inverter. Perhaps the little cigarette lighter ones just aren't big enough to do the job. My inverter is a 400watt, wired in.

    •   Really, how deep?  Head scratch?    Oh, I think I'm smelling river.

    • that worked today    friend was throwing jerk bait and 4 nice eyes slammed it. funny!   
    • Cooler than normal temperatures, clouds and rain dominated the last week and slowed down the spring progression, including bird migrations and fish spawning. However, a warm-up in the next couple of weeks could change that quickly.River systems across the entire state are running very high, and while the Memorial Day weekend has traditionally been a popular paddling weekend, recreational safety specialists are cautioning that only experienced and properly outfitted paddlers should be on rivers when they are running this high. The Lower Wisconsin River set a flow rate record this week of 42,000 cubic feet per second at Muscoda and there are no sandbars available for camping. The river is running fast and deep, with some boat launches under water.Fewer anglers were out this week due to the rain and cooler weather and those that were reported mixed success. Along Green Bay one hot spot has been out of the mouth of the Pensaukee River where anglers have been catching limits of walleye. White bass anglers had a great deal of success, with some harvesting more than 20 fish from a few hours of fishing. .
    • I believe they use the same blades so I wouldn't expect much of a difference.   
    • So what is the difference between the Lazer Synthetic and just a plain ole Lazer hand auger when it comes to cutting ice with a hand drill?  Lazer Synthetic is lighter but does it cut any better?

    • My family is going to be headed to Birch Lake near Babbitt, MN in late June for a week on a houseboat.  This trip is a graduation present for our oldest and I am hoping to make it a week to remember.   I would appreciate any advice ranging from fishing locations, bait, suggested lures, and even sites to see on the lake.  I have done a lot of searching on Google with the hope of finding someone who maybe spent a week on a houseboat on Birch but not a lot of luck.  I have about a month to prepare for the trip so I greatly appreciate everyone input.   Thanks,  
    •     I have had good luck with the "My Plate" app.... It is annoying enough to keep you honest, but simple enough to use.
    •   Yeah well once you fire that bad boy up and show her how it works, she will get impressed pretty quick!
