Here’s an excellent tip from magazine Girlawhirl, which suggests when traveling on the road to bring an adapter that can turn one outlet into four. It’s a common problem to see people huddled around the scant few outlets available but if you come prepared and ask politely, problem solved. I have a couple small two prong adaptors in my office which I take with me for this very purpose.
Recently after a horrible flight delay she was so low on laptop battery power that she just had to get plugged in. There were a few outlets in the terminal, all in use and with grown men in business suits sitting on the ground nearby. (Another thing that Girlawhirl always wonders about: why are there no plugs near the chairs?) She had to ask someone if they’d let her charge for an hour or so.
The man she approached was a lifesaver. Instead of just pulling his plug, he pulled a new plug out of his bag. He was traveling with an adapter that changed the single outlet into one that could accommodate four more devices.
