I have a generator Also, we usually bring in a few car batteries to charge our phones/run small lights. We were without power like 2 weeks during hurricane Katrina. Being right next to the gulf we have plenty of experience without electricity from all the hurricanes.
Think it was some storm... Mom said to fully charge my Macbook Pro battery. I did. It lasted for my first 4 hours on Endblock #fml
Not all outtages == storm. In Australia where I am outtages are caused because it's so hot that it melts the power lines. Plus there's always the handcrank.
