Additional information
The G4 is the most affordable Inogen portable oxygen concentrator with Bluetooth connectivity. It’s a great option for users looking for a lightweight, travel-friendly device. It can be charged via AC power in your home or DC power in a car or airplane. An external charger is also available for on-the-go convenience.
Drawbacks
The G4 has a few limitations compared to the G5. It has a shorter battery life, maxing out under 3 hours on a single battery and up to 5 hours on a double battery. It also offers fewer oxygen flow settings (1–3) than the G5 (1–6), limiting the amount of customization available.
The G4 is not water-resistant, although it can withstand light rain briefly when transferring between locations. Inogen recommends using the carrying bag for added protection and avoiding extreme temperatures below 41˚F or above 95˚F, as this can impact battery performance.
Inogen Connect App
The G4 supports the Inogen Connect App, which allows you to monitor your machine from a smartphone or tablet. The app displays:
> Filter life
> Nasal cannula life
> Battery cycles
> Battery status
It also provides software update alerts, making it easier to maintain the machine and keep it functioning efficiently. Filter and cannula reminders help you stay on schedule with maintenance tasks, and battery cycle tracking lets you know when it’s time for a replacement (the G4 battery supports up to 500 full charges).
The G4 may be a good fit for those looking for an ultra-lightweight machine with smartphone connectivity. If you need longer battery life, more flow settings, or a quieter device, the G5 may be a better fit.
