I want to travel to Tibet, and I am afraid of lack of oxygen. Is there a portable oxygen generator?

Of course there is a small oxygen generator! But it is not convenient to use on the road.

Personally, I think it's best not to use it. If you must use it, you can use medical oxygen bottles and oxygen pillows ... which are light and convenient. It's too inconvenient to carry an oxygen generator.

But it's best not to rely on oxygen.

Personally, I think it is absolutely unnecessary to use oxygen to overcome psychological barriers in Tibet. I have been to Tibet many times, and I have been to places above 5000 meters above sea level. I have only some asthma and no other problems.

The main thing is to adjust your mentality.
