Looking For A Good Quality Travel CPAP Device

Hello,

I have recently joined this forum and as I'm looking for a good quality, travel sized CPAP machine. Currently in my home, I have a ResMed CPAP machine (not sure of the exact model as I type this), and I'm looking for something that I can travel with that has similar features / functionality to my ResMed. I would be looking for one that has:

- water reservoir (don't need it heated)
- powered by batteries (would be nice, but is not mandatory)
- can use nasal pillows with machine (as opposed to facial mask)
- compact in size

I'm basically looking for something that works well, compact, and easy to travel with. I'm on the road a fair amount and I find it a pain to pack my RedMed up every time, even if I'm going out of town for a single night.

Any suggestions are greatly appreciated.

Thanks in advance!
