Hi,

I have a power notebook: a gateway 7422 with an athlon64 processor, 1GB of ram and an upgraded 7200rpm hdd. Even though it's 6 months old now it's still a very fast notebook and I'm happy with it. The only problem is that its battery lasts for 1h30 at most.

Since I don't want to buy a less powerful notebook whose battery lasts several hours, I was thinking about buying an external battery pack. I would only use this battery pack during long haul flights when I don't have access to a power outlet (economy class or business class w/o laptop power).

I'm talking about something like this: link to give you an idea

What I was wondering is if there is any kind of law that would prevent me from taking such an external battery on board of lights (especially on Canada-Western Europe flights).

Thanks!
