I have an old, but nice HP Omnibook 6000 laptop that needs plenty of juice! I will by typing for 5-6 hours far away from any sort of electrical point so I require a tip-top external battery pack that can allow me to do this. I have seen something called the Powerpad (which claims up to 12 hours per charge) - but it seems to be discontinued. Has anyone got any good suggestions for a long-lasting external battery pack for laptops (at least 5-6 hours per charge)?
