What's so cool about a power cord splitter? Sure, it turns one plug into two, but so what? The genius of this short adaptor is that you can pack it in your travel bag. So when you come upon the lone outlet in an airport, cafe, or hotel lobby that is already occupied, all you need to do is to politely ask to insert this spitter. Now you can add your line without disrupting theirs. And of course, at times you may use its doubling yourself. These little ambassadors should cost less than $2.
