Sleep Apnoea Forum Bringing Help + Support to the Patient
As part of my work I travel between Scotland and London fairly regularly, in the past mainly by air. Sadly, since the DVLA has taken away my licence, early-morning trips to Edinburgh Airport are out of the question, so I'm going to use the Caledonian Sleeper overnight train for the next few months. I've done it before (pre-diagnosis) and know that I am able to settle down on it.
Anyway, I'd be interested in hearing if anyone has experience of using a CPAP machine through the power sockets on board the sleeper? Each compartment has a shaver point into which you can plug a mobile phone charger via a 3-pin to continental adaptor - I've used it to charge a phone overnight as well as (occasionally) a laptop. There are signs that say it should only be used for electric shavers though.
At the moment, I have a ResMed S9 AutoSet (i'm still on the initial auto-titration phase of the therapy), but by the time the next journey down south comes around, I might have moved to a different machine, depending on what the hospital gives me when I go back for my next appointment. Does anyone know what current is drawn by the AutoSet's power brick? The last thing I want is to blow the electrics on the entire train somewhere outside Carlisle at 2am!
I have the offer of a loan of a battery from a fellow sufferer up here (thank you if you're reading!), which is probably the safer bet, but if someone else has already done the journey with CPAP and confirm that the power sockets in the compartments provide enough juice, I'm willing to give it a go on "mains" instead.
Thanks!

Looks like nobody has had experience of this Iwan, so looking forward to you educating us after your experience. Would be worth ringing Caledonian to ask - might even be a first for them too? Can't see the power being an issue though as they take very little power.
why dont you check with ResMed they maybe able to give some advice on the power outage etc and what plugs sockets etc it can be used in
Coming back to this some four years later... The power on the trains is unreliable, and the ResMed power supply cuts out when the voltage drops so as to protect itself/the CPAP. Consequently when I tried it out I found my machine cutting out every few minutes. Sorry it's taken so long to update! :-)
Wow that's some delayed update 
Did you get your driving licence back by the way Iwan? I know what you mean about power on the trains, so perhaps a portable battery would be a better option.
Well, I would have a small battery and have it charging and the CPAP running on 12vdc, that way when the train supplies some power it will top up the battery. However, sometimes the power on trains flicker so I don't know how that will work.
