    Question Voltage Inverters ??

    Hello -- New to the Board -- Thanks for Reading

    Is anyone familiar with the Voltage inverters that plug into the Lighter - Power plug -- Changes 12Volt to 110 Volt -- Low Wattage -- 350W Max.
    I want to Recharge Computer Laptop battery -- Camera battery - Phone Battery Etc. I just plug my 110 V home chargers into the inverter. Works Great and trouble Free on my Prehistoric 1992 Suburban but I was hesitant to use in on this car with so much gagetry / computers / etc etc.

    Is this acceptable for 99 Seville STS -- ??

    Is anyone else using one with success or Problems ?

    I just replaced the Ignition switch in the car -- it would just die at Random times. Then not for days and never at the Dealership. It took them 3 weeks to get it to do it when near a diagnostic machine. Just dont want to chance anymore electrical problems.

    Thanks -- I appreciate your Input.

    Mike

    Why hesitate? Plug it in! Blow it up, why don't you?

    No, seriously, I use a little pocket sized 75 watt one all the time on both a 1997 Eldorado and a 1999 7 series BMW which is far more complicated electronically than the Cadillacs are. I've used a 400 before on my last Cadillac.

    The worst thing that could happen is that you could blow the fuse for your cigarette lighter. I think it's 20 amps though. Just remember not to load it beyond 150 or 200 watts plugged into a lighter socket. The documentation from the inverter generally mentions that.

    I will agree with Zorb... I have used that sort of thing in all my rides with no problems.

    Zorb is right on when he says the worst thing you can do is blow the fuse for the cigarette lighter. Resist the tempatation to go to a larger fuse in that event.....

    However, fair warning, don't forget to unplug whatever is plugged in there.... leaving it on overnight can suck your battery dry.....

    Newer Cadillacs may have changed, but my 97 ETC has a live cigarette lighter all the time....

    Re: Voltage Inverters ??

    I have a 300W DC/AC Inverter for my laptop. I have never had a problem. Last summer when I drove the car to Colorado from Michigan I had it on the whole time since my Microsoft MapPoint direction software was running off of the laptop. Worked great! However, none of my inverters have ever liked being on when I started the car. they squeal, so i turn them off when starting the car also.

    I was also playing my mp3s on the laptop throught the car stereo with a tape adaptor.

    and yes. unplug it or switch it off when the car is off

    275 watts / 14.0 volts(Engine running) = 19.6 amps. Fuses protect wiring not equipment.I suggest nothing more than 275 watts.Maybe the owners manual mentions something.Just my 2 cents.

    Thanks All --

    THe Documentation with it almost seem more for a 80's Dodge Pickup with Rubber Floor Mats - roll up Windows - AM radio. But, I figured I must not be the only guy out there needing to do this.

    Thank you SIAMETARQ for Mentioning the Squeal -- that would have done it for me.

    My 99STS has a 10 Minute shut down of anything electrical. If you wanted to leave the Inverter/charger Going you have to go out and open the door every 10 minutes.

    Thanks for the help --

    Mike

    Re: Voltage Inverters ??

    My 1997 shuts power off too... I've never had a battery run down by interter. I bought my little one because when I got a telephone I used to have, the car charger was $39, available only from Sprint (aftermarket came out 2 or 3 months later), and I was unwilling to buy it for that price. The 75w inverter was $24.95 and gets used a LOT. Computer, phone, little things like that.

    The squeal is because the voltage drops - it's a battery alarm, but only full size inverters do that. the little one just shuts off for 10 seconds.

    All things being equal, I would agree. However, inverters aren't very efficient. Have you noticed how much heat some of the fanless ones generate? My 400 when loaded to 150 (has digital display) blows some fairly warm air out of it after 20 minutes or so. There's a lot of loss to heat, and to circuit inefficiency. Remember that. The manual from my inverter gave a table of watts load @ 120 VAC relative to watts and amps drawn by inverter at 12 VDC, explaining these facts. I just don't have it here. If I find it in the next couple days, I will let you know. I remember that the efficiencies worked out to be around 70%.

    Hey ZORB750, with all the modern gadgets that people use in their cars I wonder if any automakers have inverters as optional equipment?

    Yes, some cars do have a 120VAC as an option. The Pontiac Vibe has one. A co-worker of mine had the car with that option.

    Yes, and a lot of hybrids have it included with no special order. GM's trucks have a huge inverter system, I believe good for 20 amps 120V ( )! Outlets are inside and out, so you can run power equipment too. You could run a circular saw or a pretty good sized drill off of that thing!

    I know what I'm going to be using that thing for if I get one...

    My minivan (shut up) came with a 120V power outlet in the back standard. You turn it on with a switch in the dash. Right next to the outlet are A/V inputs for the LCD screen. I guess the implication is that you could plug in a PlayStation or something there.

    On inverters: I have had a couple that don't work with my laptop charger but they worked with other things. I don't know why, but it seems to be related to price. The cheaper ones would not power the laptops but they would power a portable TV. YMMV.
