Well... if our power grid drops out due to "extreme temperature variations", I have my ebook reader charged, I have a good amount of AA and AAA batteries, I have an old MP3 player ready (the kind that runs with AAA batteries), a simple portable radio, a few roms loaded in my phone's Retroarch, and a bluetooth gamepad that has a surprisingly long battery life.

I'm fairly confident I'm not at risk of getting bored. Though I can't rely that much on gaming on my phone. Still, it would hold longer than a laptop. And I could probably charge it a few times over from my laptop and power bank.
