We always manage to remember all the stuff we don’t end up needing when we pack to go on vacation. You know, the extra pair of shoes you never wear, the pomade that never quite makes it onto your hair, the book you’ve been meaning to read, but somehow never do.  We always wonder why we can remember things like that, but forget the things we really need day-to-day, like our iPod charger.  Or our Blackberry charger.  Or really, any charger that makes any electronic gadget we’re addicted to function.  Which is why we sing praises to Tumi for making this small, perfectly portable mobile power pack.  You have to charge it by plugging it into the wall with included AC adapter, but after that, it holds enough power to recharge your phone (or other electronic) five times before you’re in need of an outlet again.  It comes with 9 tips that can be swapped out in order to accommodate any electronic device we can think of, a carrying pack for them, and a carrying pack for the entire device.  So finally, avoid the devastating bag rip-apart and subsequent dull stare when you realize your equipment is dead until you (a) go home, or (b) disrupt your vacay time and go in search of an electronics store.  Now, if you forget this, we can’t help you.
