laptop power, to the max

[invictius]

I want to be able to power a laptop (6 amps, 120 watts) for long periods, hopefully 12 hours at a time. I hate the thought of a long, long plane or train journey without a pc. I don't actually have a battery for the laptop atm, but I imagine it would only last 3 hours, max. Sealed lead-acid is out, seeing they're banned on flights - and something not too heavy, hopefully. Any ideas?

If you have more than one bay for batteries, you can just rotate out spares on the plane.

But do remember that rating is the max rating for the laptop, it won't actually use that all of the time....unless that is a laptop like mine...lol

No spare slots, unfortunately. The battery costs $US200 - I'm looking at trying to spend a lot less than that.

Pick up some Li-Ions (http://www.batteryspace.com/index.asp?PageAction=VIEWCATS&Category=843) and a 12V power adapter to plug them into the laptop. Something 4000mah or more would give you a few extra hours at least, make sure it has a PCB protection circuit on it. Still not exactly cheap though. Batteries are always one of the highest cost items in any device that uses them.

universal airplane/train charger?

also most trains i have been on have regular 120v plugs for home adaptors.

Bam.

Exactly what I was thinking. Theres usually a plug under the seat. Have you looked into that?

Never been on an international flight, but soon will be. I'm a bit skeptical that a budget enomoy class airline will have a powerpoint.

How can I charge when there's no power source?

I've only seen a power point on a train in one one of the 4 states I've been to, and staff will not let you uses electronic devices on it - even with a surge protector. Their rationale is that if you're equipment is damaged by a skipe, then it paves the road for you suing them.
