Gateway Notebook Power Supply Question

I have a Gateway/Acer NV5807U and I want to buy an automobile adapter (Basically a DC/DC Adapter) The DC Jack is also the industry standard 2.5 X 5.0MM so I have a lot of options out there. I do not need it to charge the battery so my question is this can I use a 12VDC adapter (Without damage to the computer of course) I am only asking this because I see that the battery is rated at 11.1VDC and the OEM AC/DC adapter is 19VDC @ 3.42A (65W) will it work or will it damage the computer?

I am usually pretty good with electronics but when it comes to an expensive computer I want to be sure that it will work with out damage
and I am not planing on powering it directly from the cars DC Socket😱 obviously as it is not 12V more like 9-16V (Depends on if the car is running and the engine speed)

Thanks
 
you need to condition the alternator it is very rough power. i'd step it up too if you undervolt by that much the gateway will bitch at you.

btw if your car isn't putting out 13-14V at a jaunt you may want to check your charging system.

why don't you buy a generic off amazon? i got one with the right plug and wattage for $17 (8 of them actually). work great.
 
You can also consider an AC Inverter for your car. Then you simply plug in your regular laptop brick. Some vans and SUVs have them built in.
 
I got a DC/DC and AC/DC in one with multiple tips - it doesn't charge certain laptops they refuse to charge but run 100% - so be careful - if that happens and your car stalls or the plug bumps out you could end up with no juice left.

Just for reference - i have to school people on this - even if your voltage varies 3-5% you can do serious damage to the life of your battery - using not factory supplied adapters are probably the easiest way to roast dozens of batteries - i've had to school many schools on this topic after they road a cart of 30 laptops in a few months.

Even a bad charger from your gateway could roach your battery - they are that sensitive. This is not any secret you can go to every manufacturers' website gateway/dell/apple/etc they have near verbatim battery care.

trust me I've had to read the bad news to many folks who don't understand proper care for laptop batteries and improper voltage is one of the worst offenders. A good digital multimeter isn't a bad idea to check now and then. Really though you need to make sure it doesn't droop under full load.
 
Thanks Emulex I was not even thinking about my battery. I don't want to ruin the (Expensive) battery
anyway I found this on that 'bay site😀 So that should work
