Xantrex, isn’t only the King of the Southern Elves. He makes mini battery backup systems. This one’s a paperback-sized portable power source theoretically good for an extra 2.5 hours on your laptop. It also has USB ports for charging phones and other gadgets that can feed off of them. And a 12-volt car power inverter, that it can use to juice up your 110-volt gadgets, or charge its own battery from. Miraculously, it only weighs a pound. (Must use Mithril.)
