Re: Using In-Seat power on a plane
Call the airline. Empowers require an adapter that can have a two prong US or europe jack, a 12v car adapter, and/or a specific plug for certain laptops and other consumer electronics. The adapters sell for $110 or so. The airline might rent you one. They might include it in first class or business class. They might include them for anyone on the flight. Check when you get on the plane and before they close the door to the jetway...you might get a lot of "A what?" from a junior crew member.
Be fearful when others are greedy, and greedy when others are fearful. Just another form of "buy low, sell high" for those who have trouble with things. This rule is not universal. Do not buy a 1973 Pinto because everyone else is afraid of it.
