Battery life and charging

The Inogen One G4 single battery is used to charge the oxygen concentrator and it works automatically when it is attached to the device. The battery's life depends on the patient's BP meaning that for different patients with different pulse flow rates, the battery lasts a different amount of time.

  • For oxygen users and patients who have a pulse setting of 1, the battery can last up to 2 hours and 40 minutes.
  • For patients who have a pulse flow rate of 2 the battery life can reach a maximum of 2 hours and 15 minutes.
  • For users as well as patients with a pulse setting of 3 the battery lasts the shortest with the maximum time of 1 hour and 20 minutes.

So, the longest the single battery can last is for 2 hours and 40 minutes (on a pulse flow rate of 2).

Regardless of where you are, you always have ways to charge your battery and use it again. Whether you are on a trip, visiting family members or you are simply staying at home, Inogen One G4 battery allows you to pick out of the three ways you can charge your battery again.

Thus, the convenient options for charging your single battery are through:

The best thing about this battery is that the external battery charger and the DC power cord are included with the purchase of your Inogen One G4 oxygen concentrator. 

DC Power cord

The Inogen DC power cord is one of the handiest options when it comes to charging both, Inogen devices or Inogen batteries, really. Due to the reason, it can be used in a car, boat, SUV, truck or R.V it meets the users' needs perfectly.

The power cable is lightweight, therefore very easy to be carried around. It also works simply as it does not require a conventional wall power source. All you have to do is plug it into the vehicle's cigarette lighter outlet, and let the cord to the rest of the work. As long as the cable is attached to electricity, it will make sure to charge your device.

The Inogen DC power cord has the ability to fully recharge your drained battery in a maximum of 3 hours. The patients are allowed to use their G4 concentrator while the power cord is charging the device.

Surprisingly enough, if you use your G4 concentrator while charging your single battery through a DC power cord, it will only increase the charging process.

The power cord is included when purchasing an Inogen One G4 oxygen concentrator.

AC Power supply

Unlike the DC power cord, the AC power supply is compatible with conventional wall outlets and it is the most common method for charging oxygen devices.

This power supply is mostly used at home while taking care of errands, relaxing or watching a TV. The Inogen AC power supply will fully recharge the depleted single battery in up to 3 hours.

Also, another dissimilarity to the power cord is that using the G4 device during the charging cycle will take a longer time for the battery to recharge completely.

External battery charger

Purchasing more than one battery for your G4 device is highly recommended. If this is the case, then the additional cost for this external battery charger is an excellent choice.

The external battery charger works pretty simply. In order to be able to charge your device, the external battery charger requires a conventional wall outlet. The patients and users are allowed to use their G4 device simultaneously with another battery while the other battery is charging through the external battery charger.

This charger is perfect for both, staying at home or traveling. You can use it to charge your battery before leaving the house so you can have a fully charged battery while out, or you can simply leave your battery on the charger while you are running errands.

Status Checker

The owners of the Inogen One G4 single battery do not have to worry about not knowing the status of their battery. The battery consists of an onboard LCD screen that shows the life of the remaining battery as well as the battery gauge expressed in percentage. All of this information is displayed on the home screen.

Easy use and removal

The Inogen single battery is very easy to be used, charged and removed. As previously mentioned, there are many options when it comes to charging. Speaking of the usage of this battery, it is important for it to operate with a charged battery and to be attached to the G4 device that is in a need of power.

The removal is equally easy. Every user should be able to remove the battery within seconds. All you have to do is press the blue button named ''eject'' that is placed on the battery. By doing this, the battery is immediately going to be removed from the Inogen One G4 concentration base.

Then, you can either put a fully charged battery inside the device and put it back in its initial place, or charge the battery that you have for later use.

Travel companion

Even though the users are able to use the single battery at home too, the majority of the users really use it for traveling or when being out of the home. It should be your go-to-choice when living the home. By having the Inogen One G4 single battery with you at all times, you will not have to worry about the battery of your G4 device.
