This is how I use my ResMed AirMini for overlanding/camping when I go on my road trips. First, I take an AirMini. It is way smaller and more importantly, I have have humidity using humidX while still being more power efficient than my AirSense Machine. This means I can take a small CPAP battery when I go on an overnight hike or if I am without power.

Those using high pressure, will need larger powered batteries. But for those 10cm and under, a small 85Wh battery will give you enough for about 8 hours. Personally, I do not use a high pressure and therefore never need a larger battery. I also usually sleep 6-7 hours while in a tent, so power is a non-issue for me.

To charge up, I use my GaN charger when I stop at hotels/campsites. And also use my 12v car charger to keep my batteries topped up. Hope this answers your CPAP travel questions!
