The Inogen One G5 was made with the user convenience and overall performance improvement in mind, with its consistently high oxygen output, lightweight design, and great battery life all merged into one product and making it the perfect portable oxygen concentrator for all kinds of patients with different needs. Not to mention that this particular brand, similar to its fellow Inogen models, has a user-friendly interface and has been designed with easy-to-read LCD displays and simple control functions, further giving emphasis to usability and functionality. In addition, with the product’s long battery life and portability, Inogen One G5 is a reliable companion that enables the patient’s independence, carrying on with their day-to-day activities and travels with no hassle, no heavy carts, and no worries of not delivering enough oxygen (it’s FAA approved, too!).

And we’re just getting started. It’s got the Inogen, Inc. touch of superior quality portable oxygen machine and leading research in the field of oxygen therapy, alright. But why Inogen One G5? What’s it got that others don’t?

Don’t worry – we’ve got a couple things listed down that might interest you in some way:

1. It’s easy to carry around

You might be hearing portable and lightweight too many times to count, not only because oxygen therapy has generally evolved from the use of carts and heavy tanks, but also because it’s exactly what Inogen One G5 is. Completely eliminating the flaw of the heavyweight G2 (but that’s with a high oxygen output) by weighing exactly 4.7 pounds, it immediately places itself among the lightest oxygen concentrators in the market, without even compromising oxygen flow and battery life.

Convenience and hassle-free have never sounded better. With the height of approximately 8.15″ and a weight of not more than a bottle of 2-liter soda, Inogen One G5 users are spared of the burden of rolling carts and limited locomotion. You can walk around the streets and go as far as travelling by air without any troubles. With this, there’s less barrier for you to be active and enjoy you day. Seriously though, you really might want to avoid rolling carts for your oxygen concentrators.

It’s a huge weight on your shoulders (literally) and might cause injury especially if you have special attachments to your device. Plus, it’s not suitable for bumpy pavements and transportation.

2. Can be used 24/7, day and night

Just like the other Inogen models, the Inogen One G5 is clinically proven and designed for day or night oxygen use, which is especially helpful for people whose breathing rate may change or sustains shallow breaths while sleeping and would like to sleep with oxygen support. This model has a “Sleep Mode Technology” allowing your device to run efficiently not only in the day, but also reliably in the night. Paired with its ability to detect breathing patterns and giving you enough oxygen for every inhale, there’s no need to buy another oxygen concentrator at night nor worry about it shutting down on you (not when its processors are designed for about 2.3 years of continuous use).

The Inogen One G5 is also compatible with the CPAP and BiPAP machines, so to everyone with sleep disorders that’s required to use these machines for opening up your airways – we got your back (though, you should continue to consult with your respective specialists). All there’s left is for you to lay back, turn on your Inogen One G5 and sleep in the peace of its 38 decibel, non-existent noise, one of the quietest among the rest.

3. Long external battery life

This is a key feature in Inogen’s newest model, one which stands out in the “G” series of POCs and is one of the most important features in portable oxygen concentrators. The Inogen One G5’s battery is unlike those with its predecessors – it makes use of an external, easily rechargable and replaceable battery located in the bottom part of the device and can be readily removed with a pull of a tab. No need for an expert to replace batteries, nor worry about not being able to gauge your battery life, which is the case for internal batteries.

Because of the 16-Cell double battery installed, the device can continue running for up to 13 hours (at a setting of 2) and can be plugged in anywhere and anytime at your convenience with its AC power supply and DC cable. That’s up to 13 hours of uninterrupted walking, doing activities, and whatnot, without worrying whether it can last for long, for only a single charge. That makes the Inogen One G5 a contender for the longest battery life for a portable oxygen concentrator, putting a whole emphasis on what it means to be portable and convenient.

4. Impressive oxygen output

One concern with ultra-small units is the maximum amount of oxygen it can deliver, saying that the smaller the device is, the lesser the oxygen output it has. It is, once again, something that the Inogen One G5 has broken out of and even went beyond considering its 4.7-pound weight. It surpasses the popular Inogen One G4 with twice the oxygen flow setting, with a whopping 6 levels, making it suitable for both low and high-flow oxygen users. Adding its excellent 1,260 mL of oxygen output per minute to that list, too.

Inogen’s Intelligent Pulse Delivery, as mentioned previously, can seriosuly save up energy compared to tanks with continuous oxygen flow. Another point for efficiency, right there. Also, what’s a good portable oxygen concentrator if it doesn’t match your daily lifestylee and activities? With the wide range of pulse flows and lightweight features, Inogen One G5 can answer that.

And if you think it all ends there, then wait ’til you hear of this mighty perk: if you’re on your phone as often as you use a POC, then why not take advantage of both? Inogen One G5 is Bluetooth-enabled and has its own mobile application which can be downloaded for free! It’s a huge help for those who are constantly anxious about battery life and other aspects. And it literally takes minutes to set up with your Inogen One G5.

With the Inogen Connect App, you can quickly check the status of your Inogen devices by looking at your phones or tablets, including the battery status, sieve column life, oxygen purity status, and cannula and filter maintenance updates. You can also set your pulse flow settings and perform your column resets there.

And of course, it doesn’t go without the latest Inogen One G5 software updates, user manual, troubleshooting information, and frequently asked questions. If that doesn’t give you the peace of mind about whether the Inogen One G5 is working as you want even if your device isn’t by your side – don’t worry, it will.


Too long to read it through? Here’s a summary of all the great highlights of the Inogen One G5:

  • Super lightweight (at 4.7 pounds), discrete, and perfect on-the-go
  • Pulse flow settings of 1-6, the most out of the previous Inogen models
  • Maximum Oxygen Output of 1,260 mL, the most for many concentrators in the market

  • 24/7, day and night oxygen delivery
