Alternative power source for a laptop?

So I'm getting a gaming/editing laptop. It will suck power crazy fast. I'm getting an Asus G75.

So maybe when I'm not at home around my trusty outlet, I'm sitting in a waiting room or on break or in a transportation vehicle or somewhere where I can't plug in to some electricity.

I don't mind grabbing a backup [insert device that stores electricity here], whet ever it may be, and plugging into that to do what I need to do. Yeah, it'll most likely be heavy, but it's not like I'll be carrying it around ALL the time.

What am I looking for? I know I've seen some things at CES and other tech websites, but I don't know what's available right now that'll quench my future laptops hunger for power.

Anything exist that'll help me out? :confused:
 
a few lithium phosphate batteries in series to get up to the voltage you need? i believe each cell is 3.7v, if you go over you can just use a voltage regulator, it would require a special charging circuit though afaik so you don't run it completely dead and so you don't overcharge it, that or just find out what voltage the battery is and make your own connector to wire the batteries to, it should already be a standard voltage that you can get from lithium batteries (normally lithium ion but they have thermal runaway issues that lithium phosphate does not suffer from) in this case you would wire them in parallel so the voltage isn't added up (unless it needs to be, then its series)


that or use D batteries or AA batteries or something, even SLA batteries would work (read car batteries) but in any case the batteries are going to be heavy as fuck, your best bet would probably be a couple extra 9 cell batteries for your specific laptop, this is more expensive but it'd be a MUCH cleaner thing to do.


Other then all that the only other thing i can think of is making your own mini power generator with a model gas engine and a small alternator (one from a car or some shit)
