Is anyone using the HD Z2 machine yet?

While I do okay with an oral device while hiking, I really think I'd sleep much better with a cpap. Sadly, I've gotten pretty comfortable using one.

The Z2 looks to be the best lightweight option at this time. Before I buy one, I am curious about what people are carrying for batteries in order to cover the distance between charging opportunities.

Any real world insights would be appreciated.

Many thanks.
