Welcome to InspiredPortableOxygen.com, your go-to source for everything related to portable oxygen solutions!
If you're comparing OxyGo portable oxygen concentrators, two important models to understand are the OxyGo NEXT NG and OxyGo FIT Plus. Both are prescription pulse-dose portable oxygen concentrators designed for everyday portability, but they offer different advantages in weight, available settings and battery life.
In this 2026 OxyGo review, we'll compare the NEXT NG and FIT Plus, explain their practical differences and help you decide which questions to ask before purchasing.
Important: Both systems provide pulse-dose oxygen rather than continuous flow. Pulse settings are not equivalent to liters per minute. Your healthcare provider should confirm that a specific device and setting meet your prescribed oxygen requirements, including during activity or sleep.
OxyGo Reviews 2026: NEXT NG vs FIT Plus at a Glance

OxyGo NEXT NG Review
The OxyGo NEXT NG portable oxygen concentrator is the larger of these two systems. It weighs approximately 4.8 lbs with its standard battery and offers pulse-dose settings 1 through 6.
For customers whose prescribed needs can be met by this system and who prioritize longer battery runtime, the NEXT NG deserves consideration. Its standard battery offers up to 6.25 hours, while its extended battery can provide up to 12.75 hours under manufacturer test conditions.
- Weight: Approximately 4.8 lbs with standard battery; 5.8 lbs with extended battery
- Pulse settings: 1–6
- Battery life: Up to 6.25 hours standard; 12.75 hours extended
- Noise: Approximately 39 dB at setting 2
- Power: AC household power, compatible DC vehicle power and rechargeable batteries
- Maintenance: User-replaceable batteries and approved sieve columns
- Warranty: 5-year limited concentrator warranty; component coverage varies
Our perspective: The NEXT NG is worth considering when a customer wants more available pulse settings and greater battery flexibility without moving to a much larger portable oxygen system. The trade-off is its additional carrying weight compared with the FIT Plus.

OxyGo FIT Plus Review
The OxyGo FIT Plus portable oxygen concentrator is designed for customers who place a high priority on portability. At approximately 2.9 lbs with its standard battery, it is considerably lighter than the NEXT NG.
The FIT Plus provides pulse settings 1 through 4. Its standard battery offers up to 3 hours of runtime, while its extended battery provides up to 5 hours and 49 minutes under manufacturer test conditions.
- Weight: Approximately 2.9 lbs with standard battery; 3.4 lbs with extended battery
- Pulse settings: 1–4
- Battery life: Up to 3 hours standard; 5 hours 49 minutes extended
- Noise: Approximately 39 dB at setting 2
- Power: AC household power, compatible DC vehicle power and rechargeable batteries
- Design: Compact, with optional hip-worn carrying accessories
- Warranty: 3-year limited concentrator warranty; component coverage varies
Our perspective: The FIT Plus is particularly appealing when carrying weight is the customer's biggest concern. However, its smaller size should not be the deciding factor unless its oxygen delivery capabilities meet the customer's prescribed requirements.

What We Recommend Considering Before Buying an OxyGo
At Inspired Portable Oxygen, we help customers compare portable oxygen systems based on more than the numbers in a specification chart. A few practical questions often make the difference between choosing a system that looks good on paper and choosing one that fits a customer's routine.
1. Will the System Meet Your Prescribed Oxygen Needs?
The NEXT NG has six pulse settings, while the FIT Plus has four. However, a higher numbered setting does not automatically mean a particular system is suitable for a patient. Pulse-dose performance and triggering characteristics differ between devices.
Confirm the appropriate device and settings with your prescribing healthcare professional. A pulse setting should never be assumed equivalent to a continuous-flow prescription.
2. How Important Is Carrying Weight?
The difference between approximately 2.9 lbs and 4.8 lbs can matter during long outings. Consider how you plan to carry the concentrator, whether you use a shoulder bag or backpack, and how long you'll be away from home.
3. How Much Battery Runtime Do You Actually Need?
Advertised battery runtimes generally represent maximum performance under specified conditions. Customers using higher oxygen settings should expect shorter runtime than the published maximum.
Think about your typical day: appointments, shopping, restaurants, travel and time away from a power outlet. A spare battery or external charger may be just as important as the initial battery size.
Learn more about portable oxygen batteries and external chargers.
4. What Comes With the Package?
When comparing prices, confirm whether the package includes a standard battery, an extended battery, additional batteries, carrying accessories or an external charger. Two advertised prices may represent very different packages.
Also compare the warranty applicable to the exact model, including separate coverage terms for batteries and other components.
OxyGo NEXT NG vs FIT Plus: Which One Is Better?
There is no single best OxyGo for every customer. The right choice depends on prescribed oxygen delivery, portability preferences, battery requirements and daily activities.
Consider the OxyGo NEXT NG if:
- Your healthcare provider confirms that the NEXT NG meets your oxygen requirements
- You want access to a wider range of pulse settings
- Longer maximum battery runtime is a priority
- You are comfortable carrying approximately 4.8 lbs or more
- You frequently spend extended periods away from electrical power
Consider the OxyGo FIT Plus if:
- Your healthcare provider confirms that the FIT Plus meets your oxygen requirements
- Minimum carrying weight is a major priority
- You prefer a smaller concentrator for errands and daily mobility
- You can manage its shorter battery runtime or carry spare batteries
Bottom line: The NEXT NG offers more available pulse settings and longer maximum battery runtime. The FIT Plus offers substantially lower carrying weight. Neither advantage should override your prescribed oxygen needs.
OxyGo Battery Life: What to Know
Battery specifications are useful for comparing portable oxygen concentrators, but advertised maximum runtime is not guaranteed in every situation. Actual battery life varies with oxygen setting, breathing rate, battery condition, temperature and other operating conditions.
For users who routinely spend long periods away from electrical power, the NEXT NG has a significant advantage in maximum available battery runtime. For shorter outings where minimizing weight matters more, the FIT Plus may be more convenient.
Can You Travel With an OxyGo Portable Oxygen Concentrator?
Both systems are designed for portable use and are identified by OxyGo as suitable for commercial air travel. Travelers should confirm current airline requirements, required documentation and lithium-ion battery rules before departure.
For air travel, plan for adequate battery capacity, including airline-required reserves, rather than relying only on the manufacturer's maximum battery runtime.
Can You Use OxyGo While Sleeping?
Both models are designed for extended use, including 24/7 operation. However, whether a pulse-dose concentrator is appropriate during sleep depends on your individual oxygen requirements, breathing characteristics and prescription.
If you have been prescribed oxygen during sleep, ask your healthcare provider to confirm that the specific device and setting are appropriate for nighttime use.
OxyGo Warranty: NEXT NG vs FIT Plus
The OxyGo NEXT NG carries a 5-year limited concentrator warranty. The OxyGo FIT Plus carries a 3-year limited concentrator warranty.
Batteries, sieve columns and other components may have different coverage periods. Review the applicable manufacturer warranty for the exact system and accessories being purchased.
