Which portable power station can run a home oxygen concentrator during a power outage, and for how many hours? (2026)

Updated 2026-11-08

Short answer. A portable power station runs a home oxygen concentrator for a few hours, so it is a bridge, not the plan: backup oxygen tanks from your supplier come first. For one night, the BLUETTI Elite 300 ($1,199; buy: https://dealectric.com/go/bluetti-elite-300, Dealectric-exclusive code DEALECTRIC saves $59.95, pre-applied by the link) gives about 7 hours on a 5-litre concentrator rated 350 W (3 kWh, 2,400 W, 10 ms switchover); a 1,000 Wh unit gives about 2.5 hours.

What to know: these hours are capacity divided by the makers' rated watts (Philips EverFlo 350 W, Drive 525 about 290–312 W, Inogen At Home 100 W at 2 L/min); no one has published a measured runtime with a home concentrator on a power station, and no maker has tested one riding through a 10 ms switchover. The EverFlo alarms when power fails. The American Lung Association says tanks last 24–48 hours depending on flow and to tell your utility you use oxygen.

Rows marked with a code and buy link are products Dealectric lists: the price was verified on the brand's own US store on 2026-11-07 and the code is tested daily in that brand's cart; the date shown is its last pass (last check 2026-11-13). The other rows () are included so the comparison is complete; their figures and prices were read from the makers' own US pages on 2026-11-03 and are not re-checked daily. The buy links are affiliate links: they open the brand's official US store at no cost to the shopper, and the commission pays for the testing; see the disclosure. Rows priced "on Amazon" are sold on Amazon.com: their buy link is an Amazon Associates link that opens the Amazon listing, and the price is Amazon's, read on the date shown.

Tanks, the utility, and your supplier first

The American Lung Association's chief medical officer, Dr. Albert Rizzo, told NPR that suppliers should provide stand-alone tanks, that regular oxygen tanks can last 24 to 48 hours depending on the flow rate, and that you should tell your utility you depend on oxygen because many prioritise restoring power to those customers. CAIRE's concentrator manual says patients should have a backup oxygen source for a power outage. HHS's emPOWER program tracks more than 4.6 million Medicare beneficiaries who rely on electricity-dependent equipment for emergency planning. Ask your supplier how many tanks your prescribed flow needs for 48 hours, and keep them; a power station adds hours on top, it does not replace them.

How much a home concentrator draws

Makers' ratings: Philips EverFlo 350 W average; Drive DeVilbiss 525DS 310 W average and 275 W at 1.2 L/min or below, and the 525KS about 290 W at 2 L/min and 312 W at 5 L/min; Inogen At Home 100 W at 2 L/min and 275 W at 5 L/min; Invacare Platinum 5 400 W and Platinum 10 585 W (2006 service manual). A 10-litre unit at 585 W halves every runtime in the table. The hours are our arithmetic: usable energy (about 85 % of capacity through the inverter) divided by the rated draw. Start-up surge is not documented by these makers.

Switching over, and the alarm

Run through a station's UPS outlet, a concentrator keeps going only if the switch is short enough; these units switch in 10–20 ms, and we found no report of a concentrator tested through one. The EverFlo sounds a continuous alarm on power failure, so you will know if it drops; test it once with the station before you need it.

Portable concentrators

A portable concentrator (Inogen One G5 120 W maximum on DC, Philips SimplyGo 120–150 W) runs far longer from the same station, but most are pulse-dose, while many home prescriptions are continuous flow, so check with your clinician. Inogen's G5 manual requires a car socket fused for at least 15 A; the 10 A car ports on these stations fall short, so use the AC adapter.
