Suggestions for small travel CPAP machine

[jerrykur]

With the pandemic getting better we are looking to get back to travelling in the next few months.  Most of this will be by air and we prefer to carry on our baggage.  Some may be on small planes that do not have a lot of excess baggage space.  So, I am looking for something I can put in my existing carry-on backpack.  Does anyone have any suggestions?

I love my Resmed S9. It's an older model, but has proven extremely reliable and well-made. Though not explicitly designed for travel, it will fit in a backpack, no problem. If you don't need the humidifier module, it is about half the size.
