I'm afraid Sleeprider let the smoke out...

RE: The Most Likely Part Failure
I've learned my lesson. Had a brick power supply quit at night waking me up. Fortunately I had an old supply from another AirSense 10 that I could use. I ordered another brick power supply the next day. I'm on my third AirSense 10 and had 2 power supplies go bad.
I got curious and took the first power supply apart. There are slo-blow fuses on the AC in lines-both were open. After examining the components, I found a ceramic capacitor (C4) quite burned. It sits across 2 legs of Q2 (transistor). I then opened the other bad supply. Exactly the same components were bad-open fuses and burnt c4 capacitor. Don't know if the Q2 transistor went bad or not-can't find any data on it.
So, if you use an AirSense 10 or similar power supply, definitely have a back-up. You can find them cheaper than through a DME supplier.
RE: The Most Likely Part Failure
I purchased 3rd party power supplies from Amazon for both my S9 and A10 units. Since they were 1/3 the Resmed price, I was expecting potential problems. Not so! These KFD power supplies have been working for the past 4 years.

RE: The Most Likely Part Failure
AZGuy thanks for your post.
Personal experience--travelling to Cape Cod stayed in a terrible motel in the middle of nowhere. Had a violent, near-by lightning strike. Lights out. TV out. The TV never came back on. My S9E did. It was plugged into my surge suppressor-extension cord...I always use it.
Observations--scared the u know what out of me. Realized that I am totally scared about not using my machine every night. Moreso--this vacation started in Toronto, via Watkins Glen and on to Cape Cod, then returned. Had my machine died I would have packed and gone home.
I called
[DME Link Removed] Supplier #1 . They as US suppliers would not honour a Canadian prescription for a new cpap machine.
The stress was terrible until I returned to Canada and home. If I was home my DME supplier would have provided a loaner unit. However, they would not send one to me in the US.
I'm sorry you had this experience. I'm grateful you reommended a new/spare power unit.

RE: The Most Likely Part Failure
Makes me think we should all travel with a backup system, even if not of the same type. I'd rather have the use of a 10 year-old basic CPAP machine than take the risk of going one night with oxygen deprevation. More luggage, I know, but it could just sit in the trunk or separate suitcase when air travel. Can't imagine even one night without an xPAP. Upon loss/failure with no backup, I'd be tempted to go to the nearest HD for a hack with a leaf blower and some duct tape!

WakeUpTime==car's too small!
I already travel without my humidifier and water source. I've purchased an end plate for the S10 "for her" machine so I can do so. That was easier to do with my S9E; I simply unclipped my humidifier and used a different hose.
RE: The Most Likely Part Failure
I'm glad I have a ResMed machine. Followed suggestions here.
But this shows no design is perfect. Power Pack is clearly a weak link in the chain of design...
RE: The Most Likely Part Failure
Good idea, WakeUpTime.
If you upgrade your CPAP machine every 5 years, hopefully your old machine and power supply are still working. You can carry the old machine and power supply as backup. I've never had a machine go bad on me (knocking on wood right now), but the power supplies are scary. Nothing like being far away from home and have an issue with the machine, power supply or even mask/hose. I'll start carrying all with me as spares when away from home.
