Inogen G4/OxyGo FIT

Are you planning on purchasing a used portable oxygen concentrator? The Inogen-Oxygo G4 is extremely lightweight compared to any other model out there only weighing 2.8lbs. The Inogen-Oxygo G4 has been clinically tested to provide a pulse flow of oxygen up to 3 liters per minute. It provides necessary oxygen for all patients during all phases of daily life activities, including times of rest and at night for sleeping. Each concentrator is tested, reviewed, and validated by our team of experts to make sure each concentrator has the best quality parts and will last for a considerable duration of time. As a result, investing in a used portable oxygen concentrator will give you a piece of mind knowing you wont have to spend money on machine maintenance in the future.

A few things to know before you make a purchase:

As I have mentioned above all units deliver oxygen at a pulse flow. Not continuous. You will have to make sure this is something you can get used to, being able to switch from continuous to pulse. Next thing is the battery life. Because this unit is so small, the battery life is completely different compared to our other products like the Used Inogen g4 . Unlike the 8 and 16 cell for single and double batteries for the g3 and g5, the Inogen-Oxygonext G4 is going to be a 4-cell single battery or 8-cell double battery. Now depending on how many liters you are on depends on how long your battery will last. We believe you should always have a backup battery for emergency purposes. Hopefully, this information has helped you to find and pick the best portable oxygen concentrator for yourself or for your loved one. Our products are purchased and used nationwide. We also offer the best models through Inogen and Oxygo at the most affordable price out there. Please look through our amazing range of products and pick the product that best suits your needs.
