The One G4 weighs 2.8 pounds and stands at 7.2” H x 5.91” L x 2.68” W, meaning that the G4 is the smallest and lightest portable oxygen concentrator to offer pulse flow settings 1-3.

 

The small size and light weight makes the Inogen One G4 perfect for any occasion, and you don't have to worry about using it everyday because Its compressor is rated to last 20,000 hours. 

 

It’s small enough to carry virtually anywhere without physical strain to you or your body. The One G4 is the perfect travel companion, you can go by foot, plane, boat, car, etc. it has never been easier to be on the move with oxygen than it is with the G4.

You will receive a padded shoulder strap with the purchase of your One G4. This will help you be comfortable carrying your Inogen One G4 to the doctors, through the airport, or at the store. And at 2.8 pounds, you will use very little energy to carry your oxygen with you!

 

Great Battery Life

One of the biggest perks of owning a portable oxygen concentrator in general, is having an oxygen device that runs on battery power. Portable oxygen concentrator will utilize the air surrounding the device so you never run out rather than a finite amount of oxygen that would come in a tank or reservoir. 

 

A rechargeable lithium-ion battery give you peace of mind because as long as your device is charged, you will have oxygen, and there is no more waiting around for your tanks to be refilled or replaced.

The battery is what adds the real weight to any portable oxygen concentrators, so the bigger the battery the heavier the device will be. If the oxygen device requires a lot of energy, as a continuous flow portable oxygen concentrator does, the battery must be bigger and the device will be heavier. 

 

So the 2.8 pound One G4 has a relatively small battery compared to the Respironics SimplyGo which is the lightest weight continuous flow portable oxygen concentrator, however the battery life is surprisingly good for how small this machine is!

Being less restrictive with its oxygen settings and by giving you up to 5 hours of battery life, the Inogen One G4 set the bar high for competitors to follow.

 

The One G4 is compatible with two different batteries, a single battery and a double battery. The Single battery weighs less than the double battery, but it does not last as long. 

 

With the single battery, you can get up to 2.25 hours of use on a single charge on a setting of 2 and your Inogen One G4 will weigh just 2.8 pounds. This setup is perfect for making trips to the doctor’s office, running to the store, doing things around your house, and exercising.

The double battery, on the other hand, gets up to 4.5 hours of use on a single charge. Despite doubling your battery life your Inogen One G4 will weigh a mere 3.3 pounds with the double battery installed. This setup will give you the freedom and independence to travel, go to sporting events, or get dinner and see a movie.

 

 

Pulse Flow Oxygen Output

Oxygen output is the most important aspect of your portable oxygen concentrator. Your oxygen device must be able to give you the amount of oxygen you need to maintain healthy oxygen levels day and night. Oxygen flow is measured in liters or milliliters per minute. 

 

Here are the flow setting options you have with the One G4, the One G4 only offers pulse flow operation. 

 

Flow Setting Oxygen Output (milliliters per minute)

Setting 1:  210 ml/min

Setting 2: 420 ml/min

Setting3: 630 ml/min

 

Approved for Nighttime Use

Even though the Inogen One G4 is a pulse flow portable oxygen concentrator it is still approved for nighttime use while you sleep because it is equipped with Intelligent Delivery Technology. Now, the G4 won’t work for everyone at night, but as long as you don’t require a CPAP or BiPAP machine to sleep it should work for you!

 

Inogen’s Intelligent Delivery Technology is more sensitive when detecting your breath and it is more efficient at delivering your oxygen to ensure minimal amounts of your oxygen get wasted.

Here’s how Inogen’s Intelligent Delivery Technology works:

 

To make suer that you get all of the oxygen you require and the oxygen is not wasted, Intelligent Delivery Technology delivers your oxygen within the first 400 milliseconds after your G4 detects your breath. This almost guarantees that you are receiving the full bolus dose of oxygen.

 

When you sleep, breathing rate slows so the Intelligent Delivery Technology monitors your breath rate and it will increase or decrease the amount of oxygen in each bolus dose depending on your breath rate and the oxygen setting you are using.

 

Used Units Starting at $999

 

This guarantees you are getting your required oxygen!

 

If you aren’t sure if the Inogen One G4 will work for you at night, you can always speak with your doctor about it or get a sleep test to make sure before you try it yourself.



Easy to Operate

Just like the other Inogen concentrators, the Inogen One G4 is simple and easy to use. The control panel is equipped with a backlit LCD screen and large push buttons.

 

The backlit LCD screen is easy to read in direct sunlight or in the dark. It displays vital information like your flow rate, your remaining battery life, and it will notify you if anything is wrong with your concentrator. And the font is large and easy to read so you won’t have to squint to see what it says.

Operating your G4 is simple. The control panel only has 4 push buttons:

 

Power Button (standard power symbol)

Flow Rate Up Button (plus sign)

Flow Rate Down Button (minus sign)

Audible Alarm Button (bell)

 

Changing batteries on your G4 is quick and easy too! The G4 batteries are equipped with easy push-to-release tabs that allow you to change your battery in seconds. And you won’t have any difficulty getting your replacement battery installed. To make the process as easy as possible, Inogen engineered the battery slot to have a track that ensures your battery perfectly aligns with your concentrator.



Three ways to Charge the Batteries

 

Comfort Battery

 

Recharging your Inogen One G4 batteries is fast and convenient. You have a total of three different charging options to choose from:

 

  1. AC Power Supply
  2. DC Power Supply
  3. External Battery Charger

 

The AC power supply is the most common charging option. It charges your batteries faster than the DC power supply and you can use your Inogen One G4 on all 3 oxygen settings while you recharge. The AC power supply is equipped with a 110v power cord allowing you to plug it into any wall outlet. You can use it at home, in your hotel room, on a cruise ship and even some of the newer airplanes have 110v outlets at every seat.

 

While your Inogen One G4 is plugged into the AC power supply you will have an unlimited amount of oxygen. So, make sure you plug your G4 into the AC power supply if you plan on using it to sleep.

The DC power supply gives you the ability to power your concentrator and recharge your batteries on the go! It is equipped with a 12v power cord so you can plug it into the cigarette lighter or 12v outlet in your vehicle. You can take it in your car, truck, RV, or on your boat!

 

While your Inogen One G4 is plugged into the DC power supply it will recharge and supply you with oxygen on all 3 settings. However, if you are using your G4 while it is plugged into the DC power supply it will take longer to recharge. Remember to turn your vehicle on before plugging your G4 into the DC power supply otherwise, you might blow a fuse or drain your vehicle’s battery.

 

Inogen One G3 2 Battery Package

 

Although the external battery charger is an optional accessory, it is the most convenient charging option available for your Inogen One G4. It’s a single bay charger that gives you the ability to recharge your extra batteries without plugging your concentrator into a power supply. This means you can run errands, exercise, or go visit your friends and come home to a fully charged battery waiting for you!
