AC to DC inverter are they safe?

by PaBowHunter / August 21, 2005 10:48 AM PDT

Hello

I am planning a road trip to Yellowstone and Glacier National Parks. To enhance my trip, I have ordered a Dell inspron 6000 and a blue tooth GPS. Plan on using the GPS for helping us map our trip and do some geocaching. I was thinking of getting a DC to AC inverter because Battery may not last very long?? (this is my first laptop) Is this a safe move?? I was going to use a surge protector with the inverter. Don?t want to damage my new laptop on its first trip.

Thanks for any ideas
Roger

Hi the term inverter usually refers to changing DC to AC. AC to DC is usually the work of an "adapter" and I would be surprised if an adapter was not supplied with your laptop. Although cood adapters have constant output circuitry a surge protector is always a good idea when plugging into the main as electric storms can kill adapters and anything attached to it. Good surfing with your new laptop. Stewart

I did mean DC to AC. I plan on using it in my Van to keep my laptop running longer. I was told that I could only expect several hours of battery life.

The caveat here is to follow the supplied instructions.

Good idea. I use one all the time. just be sure to get one with sufficient wattage output to comfortably run your laptop. Have a good trip. Stewart

About Wattage. Get plenty.

My smallest inverter is 100Watt and the largest laptop load is 70Watts tops. So that's a safe margin. I prefer 2X safety margin, but that's close enough for non-government work.

Thanks for all the help. I plan on having a good time and the laptop should help. This is my first laptop and all I hear from my friends, is how delicate they are.

Thanks again

umm im not sure if it would work for myne...
by mtf612 / August 24, 2005 3:07 AM PDT

i tried using a 120 watt converter on the plane and it would not work... when i tried it in a car the car lights flickered....it is a 2 year old poor condition converter....so i figured it mAY have been the converter....here is my powercubes specs (powercube is the part bettween the laptop and the male ac plug) ...........

input: 100-240 v - 50-60 hz 2.9a

output: 20v 9a

do they make a converter that plugs into the ciggaret plug and converts it to work with my laptop? also how many watts does my laptop use??? thanks for your help

So 20V at 9A is 180 Watts and you have 120 Watt invertor.
by R. Proffitt Forum moderator / August 24, 2005 3:16 AM PDT

Why did you do that?

Even the flip input side is 100V at 2.9A or 290Watts so again you've overtaxed the invertor.

inverter question
by ooasiss / September 15, 2005 7:50 AM PDT

Hi, I have always wondered if this would work at all...I have a 450w inverter on my boat, connected to two deep cycle batteries which are re-charged by the boats alternator. Is it possible to plug an automotive battery charger (2amp or more)into the inverter and connected the charger cables to the deep cycle batteries to continously charge the batteries when the boat isnt running??

Hi. I'm not sure I'm interprating your question correctly but as you describe it, seems you are trying to use your on board batteries to charge themselves. I think this is akin to the quest for perpetual motion. The only way you can use your proposed setup is to use another source to drive the inverter. Good luck Stewart

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
