Portable Oxygen Concentrators
We carry portable oxygen concentrators (POCs) built for travel and everyday use outside the home. Every unit here runs on rechargeable battery power, so you can stay active, fly, and keep your routine without being tied to a wall outlet. For home-based, continuous-flow systems, see our stationary oxygen concentrators. Looking for the full oxygen therapy range instead? Browse all oxygen therapy devices.
Portable vs. stationary oxygen concentrators
Portable units are designed to move with you: they run on battery, weigh only a few pounds, and are built for pulse-dose delivery, which releases oxygen only when you inhale to conserve battery life. Stationary concentrators plug into a wall outlet, deliver continuous flow, and are built for use at home or bedside. Many people use a portable unit during the day and a stationary unit overnight or at home. Here is a quick side-by-side comparison.
- Portable: runs on a rechargeable battery, typically 3 to 10 lb, mostly pulse-dose delivery, and FAA-accepted for flying. Best for travel, errands, and active days.
- Stationary: plugs into a wall outlet, larger and built to stay in place, delivers continuous flow. Best for home use, overnight, and bedside.
How do I choose a portable oxygen concentrator?
Pulse dose or continuous flow
Pulse-dose delivery senses each breath and releases oxygen on inhale, which extends battery life and suits most active, on-the-go use. Continuous-flow delivery provides a steady stream of oxygen regardless of breathing pattern, which some prescriptions require, particularly for sleep or higher-need use. Your prescription will specify which delivery method and flow setting you need.
Flow rate (LPM)
Flow rate is measured in liters per minute (LPM) and determines how much oxygen a unit can deliver. Your prescribing physician will specify the flow setting you need; compare each product page for its maximum LPM output before choosing a model.
Weight and battery life
Portable units generally weigh between 3 and 10 lb, and battery life varies by model and flow setting, generally in the range of 2 to 10 hours per charge. If you plan to be out for a full day, look at extended or additional battery options on the product page.
Flying with a POC
Most portable oxygen concentrators sold here are FAA-accepted for use on commercial flights, but you should always confirm your specific model's FAA status and check with your airline ahead of travel, since documentation and battery requirements can vary.
Noise level
Sound output varies by model and by pulse or continuous setting. Compare the noise spec listed on each product page if quiet operation is a priority for you.
Shop by brand
We carry portable oxygen concentrators from Inogen, Oxlife, Rhythm, and Drive DeVilbiss, including the Inogen Rove 4, Rove 6, and One G4, the Oxlife Independence and Liberty (and Liberty 2), the Rhythm P2 and E6, and the Drive DeVilbiss iGo2. Explore the full Inogen collection for that lineup, or compare specs across brands on each product page.
Prescription, cost, and insurance
A prescription from a licensed physician is required to purchase a portable oxygen concentrator. We sell POCs for purchase, not rental, so you own your device outright. Pricing varies by brand, flow capacity, and battery configuration; check each product page for current pricing. Most portable oxygen concentrators qualify as FSA/HSA-eligible purchases, and financing options may be available at checkout. Round out your setup with nasal cannulas, extra batteries, or other oxygen therapy accessories.
