Re: Increasing the wattage of the A/C plug to 180w plus?

The specs for the laptop's power are as follows:

"Full Range AC-in 100~240V, 50~60Hz, 180W AC Adapter, DC output 19V, 9.47A"

Would an inverter like this work since it is 400w continuous, and cover the peak load of 330w at 12v?

lower output charger? will take longer to charge, but if topping up on the go it will likely work.

How is it lower output? It's a 400w inverter using the standard ac adaptor.

I like neiltb's idea, it's definitely the simplest so far. He's suggesting using a lower output charger for a different model of laptop. As long as it supplies roughly the same voltage, it will work. It may not be able to keep up with continuous usage, but it would still greatly improve your usage time.

With this particular laptop it can be damaged by not having enough power at the correct voltage going through it. I miss having a normal high end laptop that used a 120/150w psu. This gaming laptop uses a 180/220 psu. I didn't foresee these when I was deciding on a laptop.

And of course I figured the inverter built into the jeep would cover any need I had for it.... Which of course it doesn't.

Re: Increasing the wattage of the A/C plug to 180w plus?

do you game while driving? if you need 19V, buy a charger that supplies 19V but at a lower amperage output (5 or 6A). it will take longer to charge, but it will charge.

If your chauffeur is driving you to work and you like to play WOW on the way to the office, maybe a bigger inverter with the required wiring to ensure you don't set the car on fire, might be for you.

Most newer laptops can selectively power off the GPU. You could set up a power profile that keeps it off and just run on the integrated graphics while you are mobile. Otherwise, personally - I would just add another inverter that can handle your needs under the seat and just leave the stock one alone.

Mine has none, I've just been carrying a 180 in the trunk. Inverters are cheap.

I would just do your research before attempting to do this as I would think you could potentially do harm to the battery and/or laptop.

Re: Increasing the wattage of the A/C plug to 180w plus?

Time to get back to basics...

Do you game in the vehicle?

If yes:
Do you game longer than the battery can last?
If yes, get a bigger inverter. You can wire it in just like an amplifier and hide it under the rear seats.
If no, turn the laptop off to charge (less current draw). The factory inverter may be adequate (try it).
If No:
Do you need a computer with multi-tasking capability to use while traveling?
If yes, how about a netbook? More processing power than a tablet with power requirements that fit the factory inverter. Used netbooks are cheap (everyone wants tablets).
If no, try a tablet. Great for multimedia or communication on the road. Decent tablets are available new for under $200. And, the power requirements definitely fit the factory inverter.

Gaming laptops are great fun and also powerful enough to replace a powerful desktop for road-warriors. They just aren't practical for use in the vehicle without special preparations. I leave mine in the case and use the netbook for most computer-related/non-gaming tasks while traveling. I use the tablet (or phone) for quick communication and multimedia entertainment. I pull out the laptop for presentations and demos (and gaming in the hotel room).

As always, YMMV. Check out NBR for laptop specifics (I assume you know NBR, having a Sager).

Re: Increasing the wattage of the A/C plug to 180w plus?

Tybalt39 makes a good point...if you don't need the specifics of the gaming machine while you're actually traveling in the vehicle, it may be less expensive and less hassle to pick up an alternate device for general purpose use (email, web, etc), such as a tablet or netbook. I use my iPad for that and either leave my (work) laptop home or leave it in the bag unless I really need it use for for a specific reason.

Re: Increasing the wattage of the A/C plug to 180w plus?

Agree. My netbook ps is rated at about 100w on ac (1A input, output is 19vdc 1.58a) so figure 12v 125w and it is running Windows 7-64 with no difficulty. MacBook ps is 1.5A input somore like 180W. Tablets are less.

OTOH if you add a powered amp and speakers it goes up fast. Best use the Aux Input on the radio.
