Here's a link to the REI store's Franzus, All-in-One adapter- http://www.rei.com/online/store/Prod...1-c419136671f1. I've had one for 10 years and have yet to go anywhere in the world where it didn't work, and where I couldn't plug in my computer. It's about 2"x2"x3". No need to carry multiple adapter plugs in a bag. It also plugs into the cockpit receptacle using the "Australia" configuration. Can't recommend it highly enough.
