Extremely light and portable. Makes shopping possible when in need of oxygen. Traveling in car is easy.
Very good for high mobility.
Cabling for batteries and chargers with on and off switches can be cumbersome to install and change around. Remembers all is lightweight.

Main downside is the noise it makes when used in side.
