Battery life and charging

The Inogen One G4 double battery is used for charging your G4 device and work automatically up to 5 hours. However, it is very important to mention that the life of the battery depends on the user's BP.

For charging this G4 double battery, users and patients have three options:

In this manner, the Inogen One G4 double battery has ways of recharging identical as the Inogen One G4 single battery. Therefore, when deciding which of the batteries to purchase consider the battery life instead of the charging options. The DC power supply, as well as the external battery charged, are included charging options with the purchase of the G4 device.

DC Power cord

Since this G4 double battery was initially made to provide more comfort in moving around, most of the Inogen users take advantage of it when traveling. Lasting for a maximum of 5 hours allows everyone who is using oxygen concentrators to freely move in and outside their house as well as travel carelessly.

However, in the case of traveling a long distance or already using a battery that is not fully charged, the patients always have an option to recharge the battery in their vehicles.

Thanks to the DC power cable, all you need to do is connect your battery with a DC power source, which can be mainly find in the cigarette lighter outlet. Such power sources can be found in almost every car, R.V, SUV, and boats.

This only means that even if you are traveling, you have an option to recharge your battery in your vehicle by using the DC power supply. With this power cable, a fully exhausted battery will take up to 5 hours to recharge.

AC power supply

In a case of not traveling a lot, or mostly using conventional wall outlets, your G4 double battery can be also recharged through AC power supply.

Such power supply uses electricity of 110 volts and will take up to 5 hours to recharge the batteries completely. The G4 oxygen concentrator is allowed for use while charging the double battery. Nevertheless, keep in mind that if you happen to use the device while charging it will only extend the charging process.

External battery charger

Using the external battery charger also requires plugging it into conventional wall outlets. This battery charger allows the users to use their G4 device while the batteries are simultaneously getting recharged.

The external battery charger, just the same as the AC power supply, uses the power of 110 volts. Patients and users also have the option to leave the batteries to recharge using this external charger while they are using another battery for their concentrator.

Status Checker

Inogen One G4 double battery has a home screen. This screen helps the users be informed about both, the battery life as well as the battery gauge. Displaying these stats helps the patients and users know when their battery is fully charged and when to recharge it again.

Easy use and removal

Then in order for the G4 device to be empowered, the batteries should be inserted in. That is how the automatic charging begins.

The process of removing the double battery is equally effortless. It is made for every owner of a G4 device to be able to quickly remove the batteries.

Travel companion

In a comparison with the G4 single battery; this battery doubles the battery life by only adding a half-pound to the concentration weight.
