Per Matt Cutts’s post
a year ago, I purchased a “triple-tap” AC adapter to put in my laptop bag.

Now when I’m at an airport or coffee shop with my laptop and need to plug in, I’m almost guaranteed an electrical outlet. If an outlet is completely filled, all I need to do is ask someone if they mind splitting the outlet with me. Really, who’s going to say no to that?

Just a little tip that I thought I’d pass along. I used it today while at Caribou Coffee.
