WTP and CW - in-seat power
 

What exactly does BA mean by in seat power for WTP and CW. I have the opportunity to upgrade my WTP seat to CW for reasonable money but, as a CPAP user need a proper power outlet. If I can use my CPAP machine and get a decent night's kip, it might be worth the premium.

Take note of the voltage and wattage limits.

Fab. Thank you. I should have been able to find that!

Interesting.

who chose 110 volts for a U.K. airline !

I only ever use usb but I assume most mains devices won’t work unless your adapter happens to have a wide voltage range

Probably designed that way to prevent passengers plugging in appliances more substantial than a phone or laptop charger (air fryer, Grorge Foreman grill etc).
Im pretty certain for medical need items such as that of the OP's there is a separate supply for them to connect to. I'd probably be inclined to raise this to the medical assistance team before travel rather than assume such medical devices will work on in-seat power.

A lot of devices, especially portable devices (think poweradapters) are mult voltage/frequency anyway.

From the manuals, pre authorisation for a CPAP is not required and seat power can be used where available. However, it states the usual caveats of unable to guarantee availability and max output is 75W.

The adapter takes 100v to 240v 50hz/60hz. I just checked.

that's a useful nugget of information. Thank you. Again looking at the unit its 1 to 2 Amps and 12v so, not being an electrical engineer I looked it up and 75w should be plenty.
