Laptop power

Our in-seat laptop power is available in our Premium Economy and Upper Class cabins, and will keep your gadgets going onboard throughout your flight.

Depending on which aircraft you're flying on, there are two types of power options of available onboard - AC power and EmPower.  

As you'll need to bring a laptop power lead with you onboard, we want to make sure it's the right one.  Which is why we've put together our guide below...  

If you know which aircraft you're flying on, use our table below to determine which power option, your cabin is equipped with - AC Power or EmPower.

If you're not sure which type of aircraft you're flying on, just log into Manage My Booking to find out. 

AC Power:

For in-seats equipped with AC Power, all you'll need is the standard wall power supply that came with your laptop or other electrical device.

The power on the plane is typically 110V AC and features a 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).
  • UK 3 Pin plug.
  • + other types of plug.

EmPower® DC Power:

EmPower features 15V DC power at up to 75 watts per outlet, so you'll need an adapter that is compatible with EmPower.

The system has a power limit it can provide to a seat.  Therefore, there may be occasions where a passengers device may draw more than the system is able to provide and will either work for a short period of time, or will not work at all.

If you're an Apple laptop owners, MagSafe Airline Adapter is compatible with EmPower outlets.

If you don't have your own lead, our cabin crew crew have Kensington power leads you can borrow upon request.


USB sockets are supplied which will power devices but not to be used for charging.
