This versatility allows you to switch between modes based on your current needs or activity level.
The Inogen One G3 focuses exclusively on pulse dose delivery with oxygen therapy settings ranging from 1–5. This specialised approach makes the device lighter and more energy-efficient.
Impact on Usage Patterns
These differences in delivery modes have a significant effect on how the devices are used. If you need oxygen therapy during the night or have specific medical conditions that require continuous flow, the SimplyGo’s dual functionality becomes crucial. On the other hand, patients who primarily need support during the day while being active often find the Inogen One G3’s pulse dose system perfectly sufficient for their lifestyle needs.
Who Is Each Portable Oxygen Concentrator Best Suited For?
Usage suitability varies significantly between these two devices based on your specific oxygen therapy needs. The Philips SimplyGo serves patients who require continuous oxygen users support, particularly those needing uninterrupted oxygen delivery during sleep or rest periods.

Your lifestyle and medical needs directly influence device choice. Sedentary patients or those with severe respiratory conditions typically benefit from SimplyGo’s continuous flow capability, while active users with stable conditions often prefer the Inogen One G3’s superior portability and battery endurance.
How Do Weight and Portability Compare Between Philips SimplyGo and Inogen One?
Device weight represents one of the most significant differences between these two oxygen concentrators. The Philips SimplyGo weighs approximately 10 pounds, making it substantially heavier than the Inogen One G3, which tips the scales at just 4.8-4.9 pounds. This weight difference of roughly 5 pounds can dramatically affect your daily activities and mobility.
The portability advantage clearly favours the Inogen One G3. You can easily carry this lighter unit in a shoulder bag or backpack without experiencing significant fatigue during extended periods. The SimplyGo’s additional weight requires more consideration when planning activities or travel arrangements.
Carrying options help offset the SimplyGo’s weight disadvantage. Philips includes a sturdy carrying bag with padded straps, and you can purchase an optional wheeled cart that transforms the unit into a rolling suitcase-style device. These accessories make transportation more manageable, particularly through airports or during longer walking distances.
The travel-friendly design of both units accommodates different user preferences. The Inogen One G3’s compact size and lighter weight make it ideal for spontaneous outings and active lifestyles. The SimplyGo’s wheeled cart option provides excellent mobility for users who prioritise continuous flow capability over minimal weight.
Your physical strength, activity level, and daily routine should guide your choice between these Philips SimplyGo vs Inogen One models, as weight directly impacts your independence and quality of life.
What Are the Battery Life Differences and Their Impact on Usage?
Battery life is one of the most important factors to consider when choosing between these portable oxygen concentrators. It directly affects your freedom and ability to continue therapy throughout the day.
Inogen One G3 Battery Life
The Inogen One G3 has an impressive battery system with 16 cells, allowing it to last up to 8 hours on pulse dose setting 2. This means you can go about your day without worrying about finding a place to recharge.
Philips SimplyGo Battery Life
The Philips SimplyGo has different battery performance depending on how you choose to use it:
