Oxlife Independence Frequently Asked Questions

The Oxlife Independence is a very exceptional portable oxygen concentrator in many ways, and these great features have spurred many questions from those shopping for the right portable oxygen concentrator.

Q: How long does the battery keep a charge?

A: At the highest pulse dose setting, the Oxlife batteries last for around 6 hours. You can expect around 5 hours of charge on the highest continuous dose setting. There are two batteries you can use, and these duration times are based on the use of both batteries. If you are traveling by car and you use 2 LPM or less, you will be able to charge the battery as well as run the concentrator from the car's battery at the same time. If you need more than 2 LPM continuous flow, you can run the concentrator from the car's battery, but you just won't be able to charge at the same time. If you need more time with 100% mobility, you can purchase more batteries, so you can switch them out when you're on the go.

Q: Will the Oxlife work as well at a higher elevation as it does at sea level? How high can it go and still give me the right oxygen purity?

A: Some portable oxygen concentrators can only go to around 10,000 feet and still be able to give you the amount of pure oxygen that you need. The Independence is exceptional, as it can travel to around 13,123 feet above sea level and still bring in enough oxygen to give you the purity that you would get at lower altitudes. This portable oxygen concentrator is perfect for those who live in very high altitudes, or for those who like to travel to these areas.

Q: Can I use this concentrator at night with CPAP?

A: The Independence has capabilities for both CPAP and BiPAP, which covers obstructive sleep apnea and central sleep apnea respectively.

Q: How easy is it to move around, since the handle is attached to the machine itself?

A: This portable concentrator is one of the larger ones, since it has both continuous and pulse dose settings, as well as all of the other great capabilities. Therefore, it can only be moved around via a cart, so it was designed to eliminate the need for getting a separate cart. The 6 inch wheels make it easy to move around, even on bumpy and uneven surfaces, and absorbs any shock. The handle is very easy to fold down and out of the way when you are sitting still.

Q: Will I be able to fly with it?

A: Like all of our portable oxygen concentrators, the Independence has been approved by the Federal Aviation Administration for airline travel. You should always notify your airline 2 weeks ahead of time that you will be bringing a portable oxygen concentrator on board with you. The concentrator, as well as your accessory bag, will not be counted as carry-on.

      There is a desktop charger that you can purchase for this unit that will allow you to charge the batteries outside of the machine.

      Hi. I think there are 2 things needing to consider:
      1. How old is the unit? If over 3 years old, It might need to be repaired.
      2. Call the manufacturer with the serial number and they can look up the age of the machine. If you did buy it from us we can do it for you.

      But give us a call and we can help you navigate some of this either to a repair or new machine.
