What to Look for in a Battery Operated Oxygen Concentrator

Portable oxygen concentrators (POCs) are becoming quieter, more portable, more energy-efficient and less expensive every day. While portable oxygen tank systems only allow for carefully timed outings, the latest portable oxygen concentrator systems allow you to do much more. With today’s portable oxygen concentrators, you can enjoy lunch and a movie with friends, spend more quality time with out-of-town family members and even travel across the country, all with your POC by your side. But what should you look for in a battery operated oxygen concentrator, and how do you know which one is right for you given so many choices? Read on to learn about a few of the most important things to consider for you and your oxygen needs.

Battery Life

battery operated oxygen concentratorBy far, one of the most important aspects of a portable, personal oxygen concentrator is the amount of time it allows you to be mobile, as it runs on a rechargeable battery. But knowing the advertised battery life of a particular POC’s battery is not enough; manufacturers often advertise the battery life consistent with the lowest possible setting.

You must consider how much battery life you’ll have when using the POC at the oxygen setting you require. For example, if the manufacturer’s advertised battery life is 4 hours on a pulse-dose setting of 2, it might only last 3 hours on a pulse-dose setting of 3. This is very important to understand, especially if you lead an active lifestyle and enjoy doing things away from home. Some POCs, like all the Inogen One models, give you the option of purchasing a double battery. For Inogen One models, this provides you with up to double the battery time listed for the battery life (at flow setting 2) with the single battery.

Pulse Dose or Continuous Flow?

There are two main types of POCs available: continuous flow and pulse dose. Which you choose will depend upon your oxygen needs and personal preference. Continuous flow POCs deliver oxygen continuously at a constant rate. This means regardless of whether you are inhaling or not, the oxygen is still flowing. Depending on how much oxygen you need per minute and when you need your oxygen concentrator, your doctor may suggest a continuous flow device as the best choice for you.

Pulse dose POCs, on the other hand, deliver oxygen based on the user’s breathing rate and inhalations. These types of POCs are generally recommended for people who do not have high oxygen requirements per minute. Your health care provider can help you choose which POC to pick based on your condition and individual needs.

Size and Weight of Unit

Most people purchase a POC because they don’t want to be tied down to a heavy oxygen delivery device. As such, the size and weight of the device, including the unit’s battery and accessories, are probably very important to you. Because continuous flow devices are able to meet a wide range of oxygen demands, they are generally bigger and heavier than pulse dose oxygen concentrators. A continuous dose home oxygen concentrator can weigh about 18 pounds or more, depending on the manufacturer. Though an 18-pound oxygen concentrator can be moved around the house, heavier options may not be possible to move without a cart. Pulse dose units are typically much smaller and lighter, with some weighing less than 5 pounds. These units are so light and compact that they can be easily carried and often come with a handy carrying case that you can strap across your shoulder or a lightweight backpack for ease of use. Inogen One models range between 4.8 pounds for the Inogen One G5, with the longest battery life available in Inogen POCs, to as little as 2.8 pounds for the Inogen One G4, which is as small as a pound bag of coffee.

How Much Oxygen Does the POC Deliver?

Before you choose a POC, it’s important that you know your oxygen requirements at rest and during activities and sleep so you can better understand which unit will deliver the amount of oxygen you require to maintain your oxygen saturation. Continuous flow POCs deliver oxygen in liters per minute (L/min), usually ranging from 1-3 L/min, whereas a pulse dose unit administers a volume (bolus) of oxygen in milliliters per breath (mL/breath). Usually, continuous flow POCs deliver up to 3,000 mL/min, while pulse-dose POCs deliver between 450 mL/min to 1,250 mL/min. Your health care provider and oxygen supply company will help you determine which choice is best for you, depending upon your typical oxygen saturation and your oxygen needs.

Approved for Flight by FAA?

As of May 2016, the Federal Aviation Administration (FAA) allows oxygen-dependent passengers to carry their own POCs on board all U.S. domestic and international flights beginning and ending in the United States if the POC satisfies acceptance criteria and bears a label indicating conformance with the acceptance criteria. This rule also allows for older, previously FAA approved models to be used. Because these models will not have the label, airlines may use the approved list available in Special Federal Aviation Regulation (SFAR) 106 to determine its eligibility. If you plan to travel by airplane, you’ll want to choose one of these. Please note, the Inogen One, Inogen One G2 and Inogen One G3 are all approved by the FAA for in-flight travel, while the Inogen One G4 and Inogen One G5 both meet FAA requirements.

Warranty

Most POCs come with a standard, 3-year manufacturer’s warranty. Some companies, including Inogen, give you the option of purchasing a longer warranty for an additional charge. The Inogen One G4 and Inogen One G5 both offer optional Freedom Packages, which include a lifetime warranty, along with additional batteries. Be sure to check warranty information when purchasing a POC and consider the included warranty, and extended warranty options, when looking at the overall cost and value of the unit.

The Bottom Line

Choosing the POC that’s right for you is one of the most important decisions you’ll ever make. Your primary health care provider or pulmonologist can assist you in determining whether a continuous flow or pulse dose device would work best for you based on your individual oxygen needs. Once you know this information, you can compare the features and benefits of a variety of battery operated oxygen concentrators that are currently on the market.

    I am interested in the Inogen 3 model.

  2. Avatar Jade Brunet says:

    Thank you for this information concerning what one should look for in a battery operated oxygen concentration. It is nice to know that battery life is an important aspect to consider. It would be nice to have up to nine hours of battery at a time.

  3. Avatar Russell Esposito says:

    What is the weight of each of the batteries and what is the time required to "re-charge" the batteries? In addition,
    can a POC be "plugged in" to a standard" electrical outlet, thereby preserving the battery life : able to select "charge"
    when in ""this mode of operation? What all is included in the "Basic Imogene One; OneG2; and OneG3? Are these
    POC's covered by Medicare and Medicaid? What would be the "average" monthly "out of pocket expense" for each
    of the above referenced machines? Does the respective
    POC's each have a "stand alone" home concentrator that
    is included in the different Inogen Models? What are its
    dimensions and weight?

    I am using Oxygen concentrator at home. Can i purchase a battery which is suitable for this concentrator. I require 2-3 litres per minute.

    1. Inogen Inogen says:

      Hi Kirthi, The Inogen at Home was designed for home use only. For power, the Inogen at Home uses an AC power cord rather than batteries. Since you only require 2-3 liters per minute, our newest model the Inogen One G4 may be a good choice for you. With 3 flow settings and at only 2.8 pounds, the Inogen One G4 is battery-operated and can give you the portability you desire: https://www.inogen.com/products/g4-systems/

      Our other portable options, the Inogen One G2 and Inogen One G3 are slightly heavier than the Inogen One G4 but they are also battery-operated and easily portable. For more information on each please see the links below.
