Their “no battery advantage” is just the opposite. If you lose power to the 14v plug in outlet circuit, then you also lose Oxygen. 
 

You have to carry a portable oxygen tank as backup. With an Inogen you can just toss in an extra battery. 

A lot of wrong in that comment. 
 

if you lose power and you’re on oxygen you should be descending and looking for somewhere to land. 
 

the portable oxygen tank is not required. It is however a nice to have. 
 

compared with the inogen which is very limited in its use, the Aithre is very light. I don’t think it has the same altitude limitations as the inogen.

Aithre is a small company focused on aviation. They have some interesting products in the experimental market. I did not have good luck with their forehead/ear oximeter but their service was good. 

You could probably call them and chat about pros and cons.

The point is that if you have Aithre, and you lose power you will be facing both loss of oxygen and loss of power.  With Inogen you will only face loss of power.  Loss of oxygen will only make a helmet fire worse.

And BTW, I said loss of the power to the charging circuit.  That could be a breaker issue on that circuit rather than a total loss of power to the plane. 

And BTW if someone wants a light Inogen just leave the battery off and run it on plane power like @Pinecone says he does in the Inogen topic.

And if you’re worried about those things you can use the supplemental bottle. 
 

these portable generators are NOT good above 15k for two people or 18k for 1. Pressurized bottles and on demand delivery is by far cheaper, and better in every scenario anyway, so I don’t know why anyone would consider this. (Yes, I have tested this scientifically and am working to put together the data)

Includes a backup: "a simple Aithre fixed flow 47L oxygen bottle is provided with the kit for emergency backup. This lightweight carbon fiber composite bottle provides for 2 hours of continuous flow at approximately 0.5 LPM for an added layer of safety."
