Portable and stationary oxygen concentrators serve different needs. A portable oxygen concentrator is designed for mobility and usually runs from rechargeable batteries, while a stationary concentrator is designed mainly for longer use at home from mains power. The right choice is the one that can deliver the flow mode and oxygen setting prescribed for the person—at rest, during activity and, if required, during sleep.
This India-focused guide explains the practical differences, including pulse-dose versus continuous-flow delivery, battery backup, home electricity, airline travel and service support. It is a buying framework, not a substitute for an oxygen prescription or clinical assessment.
Portable vs stationary oxygen concentrator: quick comparison
| Decision point | Portable oxygen concentrator | Stationary oxygen concentrator |
|---|---|---|
| Primary use | Moving around the home, appointments and approved travel | Regular oxygen therapy at one main location |
| Oxygen delivery | Many compact models use pulse-dose delivery; some larger units also offer continuous flow | Many home units provide continuous flow; verify the exact model |
| Power | Rechargeable battery plus compatible AC/DC power options | Mainly mains electricity; a separate emergency backup plan is important |
| Mobility | Designed to be carried or wheeled, depending on size | Usually moved only short distances within the home |
| Output range | Varies widely; compact size can limit continuous-flow capability | Often suited to prescribed continuous flow for home use, within the model's rated range |
| Travel | Potentially suitable for travel, subject to medical and transport approval | Generally unsuitable for routine travel |
| Best fit | People whose tested prescription and breathing pattern match the device while active | People who mainly need oxygen at home or require a compatible continuous-flow setting |
Direct answer: choose a portable unit for mobility only when it meets the prescribed flow mode across the activities for which it will be used. Choose a stationary unit when dependable home use and continuous-flow capability matter more than portability. Some people use both: a stationary concentrator at home and a clinically matched portable device outside.
What is a portable oxygen concentrator?
A portable oxygen concentrator (POC) draws in room air, removes much of the nitrogen and supplies oxygen-enriched gas. It is built around a smaller compressor and sieve system, with battery operation for mobility. For example, Philips describes the SimplyGo Mini as a travel-ready portable concentrator with five pulse-dose settings. That does not mean every setting suits every prescription.
Compact POCs are attractive for appointments and daily movement, but their output, battery runtime and triggering behaviour vary. A person should be assessed using the exact device during the activities that matter, particularly walking and sleep if either is part of the prescription.
What is a stationary oxygen concentrator?
A stationary or home oxygen concentrator performs the same basic concentration process in a larger mains-powered cabinet. It is designed for use at one location and often provides continuous flow within its rated range. The Philips EverFlo 5-litre concentrator is one example listed by MareeZon for home comparison.
A stationary unit still needs ventilation, routine care and a plan for power cuts or equipment failure. It is not an oxygen reservoir: when electricity stops or the device fails, it cannot continue producing oxygen unless supported by a compatible backup arrangement.
Pulse dose vs continuous flow: the most important difference
Continuous-flow oxygen
Continuous flow supplies oxygen throughout the breathing cycle at a prescribed flow rate, commonly expressed in litres per minute (LPM). Many stationary concentrators offer this mode. Some larger portable units may also provide continuous flow, but the available range and battery duration must be checked model by model.
Pulse-dose oxygen
Pulse-dose equipment senses the start of an inhalation and delivers a measured bolus of oxygen. It can conserve oxygen production and battery energy, which helps make a device smaller. However, successful delivery depends on the device reliably detecting the user's breath.
A pulse setting is not automatically equivalent to the same number in LPM. A setting of “2” on a pulse-dose machine must not be treated as 2 LPM continuous flow. Pulse volume and delivery algorithms differ by model. Only the prescriber or respiratory team should match and adjust the setting after assessment.
Who may prefer a portable concentrator?
A portable model may be considered when the person:
- needs prescribed oxygen while walking, attending appointments or leaving home;
- can trigger the device consistently and maintain the clinician-defined oxygen target on the exact model;
- can manage its weight, controls, cannula and battery changes, independently or with a caregiver;
- has access to enough charged batteries and compatible power supplies for the planned journey; and
- has received any required airline, railway or medical clearance.
MareeZon currently lists the Philips SimplyGo Mini portable concentrator and the Philips SimplyGo portable concentrator for comparison. Confirm current availability, included batteries and accessories, delivery modes and prescription compatibility before ordering.
Who may prefer a stationary home concentrator?
A stationary unit may be the more practical primary device when the person:
- uses oxygen mainly in one room or within the home;
- has a prescription that requires compatible continuous flow;
- expects longer daily operating periods and has reliable electrical power;
- does not need to carry the concentrator outside regularly; or
- needs a higher flow range than a compact portable device can provide.
If the main question is capacity rather than mobility, read MareeZon's 5L vs 10L oxygen concentrator guide. A higher-capacity machine should never be selected simply because it sounds more powerful; it must fit the prescribed flow and intended clinical use.
10 checks before buying an oxygen concentrator in India
1. Start with the written prescription
Confirm the flow mode, setting, hours of use and whether oxygen is needed at rest, during exertion or during sleep. Do not select a device from a spot SpO₂ reading alone.
2. Confirm pulse dose, continuous flow or both
Ask for the exact model's technical specification. Marketing terms such as “5 setting” or “5 litre” do not establish that two devices deliver oxygen in the same way.
3. Test the exact device where possible
A clinical team may need to confirm saturation and symptoms while the person uses the model at rest and during normal activity. Pulse triggering can be affected by shallow breathing, mouth breathing, exertion and sleep.
4. Calculate realistic battery coverage
Battery duration changes with the selected setting, battery age, breathing rate and environmental conditions. Plan from the manufacturer's stated runtime for the exact configuration, then allow a safety margin and charging time.
5. Make a power-cut plan
In areas with unreliable electricity, discuss a suitable backup with the oxygen provider and clinician. This may include charged batteries or a prescribed oxygen-cylinder reserve. Ensure the caregiver knows whom to contact if the device alarms or stops.
6. Check travel rules before departure
For flights, contact the airline well in advance. A manufacturer's aviation compliance statement does not replace the airline's approval, medical forms, battery limits or current Indian airport requirements. Carry the prescription and keep spare batteries in accordance with airline instructions.
7. Review alarms and user controls
Look for clear indicators for power loss, low battery and device faults, plus any oxygen-concentration or breath-detection alarms stated by the manufacturer. The user and caregiver should understand each alarm before taking the equipment home.
8. Check home fit, heat and sound
Allow the manufacturer-specified clearance around air inlets and outlets. Do not place the unit in a closed cupboard or cover it. Consider operating sound, tubing routes and whether heat from the machine will be comfortable in the intended room.
9. Confirm consumables and service support
Ask which nasal cannula, tubing, filters, humidifier bottle and batteries are compatible; which items are included; and how replacements are obtained. Verify warranty terms, preventive-maintenance requirements, service turnaround and a backup option during repairs.
10. Verify the seller and device documentation
Request the exact model identity, invoice, manufacturer information and applicable Indian regulatory documentation. Check that the device and accessories match the prescription when delivered.

Oxygen safety at home and while travelling
- Keep oxygen away from smoking, vaping, flames and heat. Oxygen supports combustion and can make a fire burn faster.
- Use the electrical supply, charger and batteries specified by the manufacturer. Avoid improvised adaptors and damaged cables.
- Keep the air intake unobstructed and follow the cleaning schedule. See the oxygen concentrator maintenance guide.
- Route tubing to reduce trip and entanglement risks, especially near beds, stairs and doorways.
- Do not change the prescribed setting, add a humidifier or connect another device unless the clinician and manufacturer permit it.
- Keep the provider's contact number, prescription and emergency plan accessible to the user and caregiver.
Portable, stationary or both: a simple decision framework
- Match the prescription first: eliminate any machine that cannot supply the prescribed mode and range.
- Map daily use: list the hours spent at home, outside, travelling and sleeping.
- Assess the exact device: confirm oxygen response, triggering, noise, weight and caregiver usability.
- Plan for failure: account for power cuts, depleted batteries, servicing and emergencies.
- Compare total support: include batteries, accessories, consumables, warranty and local service—not only the machine price.

Frequently asked questions
Is a portable oxygen concentrator better than a stationary one?
Neither is universally better. Portable concentrators prioritise mobility and battery use; stationary concentrators prioritise dependable home operation and often continuous flow. Prescription compatibility decides which is suitable.
Does every portable oxygen concentrator give continuous flow?
No. Many compact portable models provide pulse-dose oxygen only. Some larger portable units offer continuous flow as well. Check the exact technical specification and prescription.
Is pulse setting 2 the same as 2 LPM?
No. Pulse settings are not automatically equivalent to continuous-flow litres per minute. The oxygen delivered per breath and the device algorithm vary, so the setting must be clinically matched.
Can a portable concentrator be used during sleep?
Only if the prescriber approves the exact device and mode after appropriate assessment. Some users may not reliably trigger pulse delivery during sleep, and oxygen needs can differ from daytime needs.
Can I take a portable oxygen concentrator on a flight in India?
Potentially, but approval is airline-specific. Contact the airline before booking or departure, complete any medical forms and follow its battery and onboard-use rules. Do not rely solely on a device's general aviation claim.
Can a portable concentrator replace a home concentrator?
Sometimes, but only when its delivery mode, output and duty cycle meet the full prescription. Battery charging and backup planning also matter. Many users retain a stationary unit as their main home system.
What happens to a concentrator during a power cut?
A stationary unit normally stops producing oxygen. A portable unit can continue only while a charged battery is installed. Follow the clinician and provider's written backup plan rather than waiting for an outage.
Should I rent or buy an oxygen concentrator?
Renting may suit short-term or changing requirements; buying may suit a stable longer-term prescription. In either case, compare exact device suitability, maintenance, replacement support, hygiene processes and the total cost of batteries and consumables.
