Doing an elk hunt in Montana this fall. First one since I was diagnosed with sleep apnea. Horseback to camp and back.

I've lost some weight and plan to lose more, but I think it's best to pack the dam machine anyway.

Anyone have recommendations for the best small cpap (bipap), a battery, and a solar charger?

What my buddy has done in the past is used an inverter connected to a 12v and solar charger. Seemed to work for him pretty well.

Costly but may be what you need.

The CPAP machine is about the size of a soda can. Then get a Extra battery.

I saw that thing. And it is dam expensive, but you're right, it may be what works. Thanks.

It won't seem all that expensive when you're freezing your butt off. Been there, done that.

I use a power convertor off a deep cycle battery and it works well

I use mine with a power inverter and a deep cycle battery. I remove the humidifier and only use the blower part to save on electricity.

I've done the inverter/deep cycle battery thing... its a pain and not practical for an elk hunt. I got the mouthpiece last year and it works pretty well for travel and camping.

When I went on an international flight a couple years ago, I borrowed a battery pack from a friend. I can't find it online now, but these two sites have some stuff worth considering... still kinda pricey though.

Ask your doctor or dentist about a Mandibular Advancement Device(MAD) or Oral Appliance Therapy (OAT). Most OSA patients can be treated with a 'mouthpiece' which requires no batteries.

I have one of these too... it works ok but not as good as the cpap.

Or try one from puresleep.com for $60 -- I can't sleep without mine
