My number one travel tip after:
-Do whatever it takes to get carrier status (thereby allowing airlines to treat you like an actual human being).
Is to always travel with a power strip (above, far left). I know it sounds pretty stupid, but the photo above is just some of the stuff I need to plug in when I get to a hotel. So if you don’t have a power strip you have to plug-in stuff all around the room (if you are lucky enough to have a room with more than one outlet). This can lead to leaving things behind when you checkout.
With a power strip, everything is all together in one place so you generally don’t leave anything behind. Power strips also come in handy when you are at the airport and all of the outlets are taken by cranky passagengers. Just politely ask if the current plug squatter minds if you deploy your power strip and everyone will be happy and fully charged. Finally, having a power strip means that you only need to carry one power adapter if traveling internationally. Because if you travel with a phone, computer, camera, DSLR, iPad and iPod the last thing you need is more crap to tote around. [Monster Travel Power Strip $14]
Update below: Here’s how I do this in Japan with a power strip bought at Muji in Tokyo. Eric this may be even better for you, knowing how much time you spend in Japan.
