Take a powerstrip. On endless amounts of travel, i've found that having a powerstrip in your bag with all of the stuff in it plugged in inside the bag allows for you to plug in one cord without exposing what you are charging to everyone around. Secondly, if you take a laptop, make sure to get an extremely strong sleave for it. I've dented my macbook in travels. Third, and this is entirely up to you, i always use the crappiest looking bag i can get my hands on for the outside of shell. People seem to assume that if it's a crappy bag, it contains crappy stuff. I like that post about the lock down pac or whatever. Hope you read this.
