Given limited laptop battery life, how can I use a car battery to power my laptop where no AC power is available? Answered

Current laptop batteries are not really suitable for powering a laptop for 10-12 hours (without using multiple batteries I suppose, and then dealing with the need to recharge them) so I am wondering if there is a way to use an automotive battery and some sort of converter to plug the laptop ac power supply into in those areas, typically outside where standard 120 VAC is not available.

As always, Google is your friend.

1) Buy a voltage inverter for your car. Then plug your laptop into it as you would any other outlet.

2) Buy a car adapter for your laptop. Some brands have them, some don't.
