Not well known, but the Dreamliner (even in cattle class)has multi type 110v AC sockets. Look under the seat squab (behind your legs)under the armrests. There are 2 per 3 seats. If you check your Laptop or CPAP power supply, they are usually 100v to 240v.
You can use these to keep your laptop powered up to watch movies for the whole duration of your flight.
Both Jetstar and Resmed confirmed these safe to use my CPAP on the overnight flight to Brisbane. If they are safe for medical devices, they would be safe for laptops.
