If you live on the East Coast of the United States, you are no doubt bracing for hurricane Irene.
In addition to all of the precautions that your local news is broadcasting on a loop, you might want to think about your gadgets.
In the event of a power outage, I can live without pretty much everything, but I do want to keep my mobile functional so I can maintain communication with loved ones. My plan is to charge up the two batteries I have, which is obvious. My less obvious precaution is that I am charging up old laptops so I can plug my phone into them should I need additional power.
