For air travel, I really like my Xreal Air glasses now that I have a newer iPhone 16pro. Just plug in the USB-C cable, and you have a virtual 60" screen in front of you which works perfectly for Netflix, etc. And they cost less than 10% of the cost of an AVP, and are not limited to 2-3 hours of battery life (they get power from the phone).

Note that if you have an older (lightning) iPhone, don't bother with these. They require a pair of dongles. Not only does that make things really awkward, but one of the dongles ends up apparently blocking HDCP, and prevents you from using anything but ... your own... downloaded content.

As I get older, a gin and tonic (or two) is what makes air travel more relaxing.

Taking a flight as an opportunity to indulge in a moment of blissful idleness is great... on a three-hour flight.

But on a 14-hour trans-continental flight, you've gotta have something to do. If nothing else, to distract you from how uncomfortable it is to be effectively confined to your seat + a few feet of narrow walkway for that long. That's more confined than a prison cell!

Nah. I do Europe-Korea frequently, and I've definitely slowly settled into a happy optimum of sleeping 7-8 hours inbetween the meals.

Killing time is a rather slower flight experience than being unconscious.

I'm very happy WiFi continues to be an expensive opt-in product. If it was always-on, I'm sure I'd break the above habit.

With my CPAP need that's not going to work :(

Knowing nothing, I was curious (there's also an apnea comment). It seems travel CPAP and APAP (auto pressure) is a thing, but travel BiPAP (inhale/exhale pressures; required by some conditions) not so much. A recent reddit comments suggest non-existent (exhalation relief only). Most all need Heat Moisture Exchange plugs. Yet I noticed eg the Philips BiPAP Pro Bi-Flex, bit of a brick (1.5 kg; 2500 linear cm - but qualifies as a medical device), but its spec says ok for airlines w/o humidifier attachment. So I'm puzzled.

So airlines allow 2 batteries of up to 160Wh (with airline approval) and as many 100Wh batteries as you can carry [note: I have not actually tried to show up to the TSA security line with a suitcase full of 100Wh batteries, so your mileage may vary].

A BiPAP machine uses 50-150 Watts, according to a random Google query, so you're looking at somewhere between 500 and 1400 Wh of total storage to get your 9 hours of sleep on a plane.

So what you're looking for is (a) a way to daisychain these batteries together so that you don't need to wake up ever 40 minutes to 2 hours to swap batteries and (b) a way to plug in your BiPAP machine, if your battery packs are all USB-C and your BiPAP isn't.

Ehm this is not really accurate. Not many people use a BiPAP machine. They're only for very old people who have serious difficulties breathing. A BiPAP machine can serve a largely different pressure for exhaling and inhaling, a normal CPAP machine can only do that with about 2cmH2O difference which isn't a lot. But normal people have no issue exhaling against the output of a CPAP anyway so it's not a problem.

For this reason BiPAPs have much more beefy motors so they can ramp up and down quickly. Or perhaps two separate motors, I have never taken one apart (I have normal CPAPs which is basically just a pressure fan in a box with some regulation electronics)

But anyway my point is, a normal CPAP doesn't use that much power. It may use more than that if a humidifier is used (which is probably not a bad idea on a plane, but it requires distilled water which is an issue to bring on the plane in sufficient quantity). Because the humidifier is just a heater and heaters use lots of power.

I don't use a humidifier, my CPAP has a PSU of about 60W but I doubt it uses more than 20. The problem is more that they are not USB-C powered, nor are there official USB-C converters for it. I could probably construct one but bringing home-built electronics on a plane is probably not a great idea either.

So yeah I don't think this will be a great option tbh. If power is provided on the plane it would work but I've never seen this on my flights except in business/first.
