Runtimes are a range because the device's draw varies. The lower figure assumes it draws at the top of its range for the whole time, the higher assumes the bottom. How we calculate runtime.

9 models cannot run this device at all

Capacity is not the constraint. These have the stored energy but their inverters cannot deliver the startup surge, so they fail the moment the device kicks in.

• Jackery Explorer 500 (518Wh): 500W continuous output is below the device's 600W draw
• Jackery Explorer 500 v2 (512Wh): 500W continuous output is below the device's 600W draw
• Goal Zero Yeti 300 (297Wh): 350W continuous output is below the device's 600W draw
• Jackery Explorer 300 Plus (288Wh): 300W continuous output is below the device's 600W draw
• Anker SOLIX C300 (288Wh): 300W continuous output is below the device's 600W draw
• Jackery Explorer 240D (256Wh): No AC inverter: this unit has DC outputs only and cannot run a mains appliance
• EcoFlow RIVER 2 (256Wh): 300W continuous output is below the device's 600W draw
• EcoFlow RIVER 3 (245Wh): 300W continuous output is below the device's 600W draw
• Bluetti AC2A (204Wh): 300W continuous output is below the device's 600W draw

For a few hours at a low flow setting, yes. For a full night at a high setting, no: nothing in the catalogue we track covers it, and no amount of comparing models changes that. A power station is a bridge to a proper backup here, not a substitute for one.

Quick Answer

• A 5L home concentrator draws roughly 90W at a low flow setting, up to 600W at a high one
• It runs continuously, with no duty cycle to stretch runtime the way a fridge has
• Nine of the 42 units we track cannot run one at all, failing on continuous output rather than startup surge
• At a low setting, a large unit covers a night
• At a high setting, no current model reaches eight hours

The flow setting matters more than the power station. Check yours before reading any runtime figure below.

Why the Flow Setting Changes Everything

Most device pages on this site can quote a runtime range of maybe two to one. Here it is closer to seven to one, because a concentrator’s compressor works proportionally harder to concentrate oxygen at a higher flow rate.

The shortlist above shows this directly: the same unit that lasts under three hours at 600W lasts most of a day at 90W. Both figures describe the same power station and the same concentrator. Only the prescription differs.

This is why a recommendation made without knowing your flow rate is worthless. A neighbour’s setup that comfortably covered their outage tells you nothing about yours.

Continuous Output, Not Surge, Is What Rules Units Out

On our fridge and sump pump pages, units fail because they cannot deliver a brief startup spike. A concentrator is different: it fails units on sustained output.

A 300W inverter cannot hold 600W for hours no matter how large its battery is. The nine excluded units named above are almost all in the 300W to 500W class, and their batteries are irrelevant to the verdict. This is the opposite failure mode to a compressor: not a spike they cannot clear, but a load they cannot hold.

The practical consequence: for a concentrator, read the continuous watt rating on the box, not the surge figure the marketing leads with. The same limit rules out the same nine units for a high-end gaming PC, which is the only other load we cover that sustains this kind of draw.

No Power Station Covers a Full Night at a High Setting

The overnight row in the shortlist above is empty, and that is the most important line on this page. It is not a gap in our catalogue. It is the answer.

At a high flow setting a concentrator needs something in the region of 4,800Wh to run eight hours, and that is before inverter losses. The largest units we track top out at roughly 4,000Wh, so even the biggest battery on the page falls short of the raw figure. Buying up does not solve this problem, and any page that implies otherwise is selling you something.

What actually covers an overnight outage:

• Backup oxygen cylinders from your supplier. This is the standard answer, it is what suppliers provide for exactly this reason, and it does not depend on electricity at all.
• Telling your utility you are on a medical priority register. Most utilities keep one. It affects how quickly your street is restored and whether anyone checks on you.
• A generator, if outages where you live are long and frequent enough to justify it.
• A power station as the bridge between the outage starting and one of the above taking over, which is a genuinely useful job and the one it is suited to.

What People Miss

Portable concentrators are a different device. A small portable unit draws far less than a 5L home concentrator and has its own battery. The figures here are for home units, and applying them to a portable is misleading in both directions.

There is no duty cycle to help you. A fridge compressor rests roughly two thirds of the time, which is why a fridge outlasts its wattage on paper. A concentrator runs continuously. Runtime estimates that feel pessimistic compared to a fridge are correct.

Pulse-dose versus continuous flow changes the draw substantially. If your concentrator supports a pulse-dose mode and your clinician approves it, it draws considerably less. That is a clinical decision, not a power one.

Test the unit before you need it. Confirm the concentrator starts and runs on the power station on an ordinary day. A concentrator that will not start on battery is not something to discover during an outage.

Cold and battery age both cut the real figure. These estimates assume a healthy battery at room temperature. See LiFePO4 vs Lithium-Ion vs Lead-Acid for how chemistry and age affect what you actually get.

The calculator defaults to the top of the draw range, which is the conservative choice for medical equipment. If you know your concentrator’s actual draw at your prescribed setting, use that figure instead.

Bottom Line

Check the continuous output rating, not the surge figure, and check your flow setting before anything else: it moves the runtime by a factor of seven. A power station is a reasonable bridge for a short outage at a low setting, and it is not an overnight solution at a high one, because nothing on the market is. Arrange backup cylinders with your supplier and get onto your utility’s medical priority register. Size a bridge for your own setup in the calculator.
