The Ultimate Guide to In-Seat Power

Port Type: AC Power

If your seat is equipped with AC Power all you’ll need is the standard wall power brick that came with your laptop or other electrical device. The power on the plane is typically 110V AC and features a semi-universal receptacle that accepts the following types of plugs:

US non-polarized 2-blade plug (both blades are the same size)
US polarized 2-blade plug (one blade is bigger than the other)
US non-polarized 2-blade plug with Ground (aka three-prong)
European standard 2-cylindrical prong plug (two round prongs)

Port Type: Cigarette DC Power

This is the same type of power port available in almost every car. On an airplane, it typically features 15V DC Power at up to 75 watts per outlet and if you want to plug in our laptop, you’ll need an adapter. Adapters are usually available from your laptop manufacturer and are often advertised as “Air/Auto” adapters. Many personal DVD players and cell phones already come with an adapter for the car which you can use right at your seat.

Port Type: EmPower® DC Power

EmPower® is the most widely installed in-seat power system in the skies today. Over 125,000 seats on 40 airlines feature this type of port. EmPower features 15V DC power at up to 75 watts per outlet and if you want to plug in your laptop, you’ll need an adapter that is compatible with EmPower. If you already have a cigarette style adapter, you can buy a small, inexpensive device that will allow you to use your cigarette adapter with an EmPower port.
