rechargeable portable power for laptop?
 

Looking for a good rechargeable portable power source for my laptop. Something I can get 6 plus hours from if required. I've seen some that are specifically meant for laptops, but the ones that just take any electrical device would allow for other uses obviously.

Buy extended battery, or two :pimp

I dropped my laptop of my bed.. working at 4 in the morning huh :(

Anyway, since having the plug connection fixed, the battery only lasts about 3 maybe 4 mins when unplugged :Oh crap
