I got this a year or so back. I really need my CPAP so it comes in handy. I fought with mine for a while too. http://www.gocpap.com/somnetics-transcend-ii-travel-cpap-machine/
try one of these masks... they are designed to diffuse the air so it does not blow on your bed partner. Really quiet too. http://www.gocpap.com/catalogsearch/result/?q=airfit
I got this one a while back and it works great. Quieter than I expected and only about the size of a beer can, I got a hook and hooked it to a nail. It will work in any direction. http://www.gocpap.com/somnetics-transcend-ii-travel-cpap-machine/
I got the battery. The rep told me the solar charger needs to be in direct sunlight to charge properly. If you get both I would email and ask for a bundle deal. They took 10% off of the battery and unit for me.. saved me close to 80 bucks. Never hurt...
