The model is small enough to carry around, and the fully charged battery lasts about four hours, so I'm satisfied that my daily needs can be fully met.

The body is compact and easy to carry on the go, just tight enough to fit in a backpack. The most important thing about a portable is that it's lightweight and easy to store and carry, and this machine is just right for my needs.

Small and portable, while the battery is removable and can be used for a long time on a single charge, which can be very convenient as a portable one.

The small and compact shape is perfect for storing and carrying on the go, and the whole body plus the backpack won't be very heavy and won't be a burden on the go, so you can enjoy relaxing and burden-free oxygen anytime and anywhere.

It is fine with the white hose but is awful noisy and the vibrations are terrible with clear hose. I love the light weight. It is so much easier to put around my waist while I clean house or mow grass. Get these to medicare facilities as they mike life so much better. Thank you Ellen
