On-the-go solution

Traveling or even visiting nearby places is probably one of the most stressful situations for the patients obligated to carry oxygen tanks. Portable oxygen concentrators were invented but they for sure cannot last forever. Like any device, they need to be charged from time to time in order to properly function.

It is not that uncommon to forget your original charger while you are on the go. That's why this DC power cord is the smartest solution for everyone living on the go. Not only is it lightweight, but it can also be connected to power sources we all have available while traveling.

These standard DC outlets can be found in your car, boat, and a vast majority of vehicles. Due to this reason, it finds a great purpose for anyone who does not prefer bringing their original charger with them.

Easy to use

This accessory is very easy to use. Besides having it with you at all times, what you should do is connect the DC power cord with a power source and let the cord do the rest of the work. The power cord will allow your Inogen One oxygen concentrator to charge as much as it needs. Later, you will have a fully recharged oxygen tank ready to use.

An absence of a power brick

Generally, power suppliers are being connected to an often heavy and bulky power brick. Well, this is not the case with the Inogen power cord.

The cord does not have any form of a power brick, which only makes the Inogen One G3 DC power cable perfect for use.

Automatic charging

As mentioned above, the DC power cable works when connected to DC adapters such as the cigarette lighter outlet you all have present in your cars, boats, and trucks. Once the connection between the electricity source and the battery is established, the cord provides automatic charging of the battery. The power input is not bigger than 15.5 Volts and not lesser than 13.5 Volts.

The DC power cord has the ability to charge both, 8-cell and 16-cell battery units.  After the recharging is done, the G3 oxygen concentrator users are able to use their device freely.

Real-time charging

Inogen One G3 can be either an 8-cell battery unit or 18-cell battery unit.

If you are using the DC power cord to charge an 8-cell battery it will take you a maximum of 3 hours to fully recharge the battery. If you are using the power, cable to recharge a 16-cell battery it will take you a maximum of 4.5 hours for recharging the depleted battery.


The Inogen One DC Power Cord is an accessory that is very convenient for the patients. Not only it is lightweight and extremely portable, but the cable itself is also, in fact, a perfect length of 6 feet. Because of this reason, the patients do not have to worry about restricted mobility due to short cord lengths.
