Power stations for a home oxygen concentrator: which are enough
Of the 54 power stations in the Enough Watts data set, 17 are enough for 8 hours of nonstop use, 36 run it but not long enough, and 1 cannot power it. The closest fit is the BLUETTI Apex 300 (2,765 Wh), with 8.1 h of this routine.

The setup
The loads, with the goal of 8 hours of nonstop use
Counts the running watts for every hour you enter.
Starting watts not published; motors often need 2 to 3 times their running watts to start.
Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.
For medical equipment, confirm the power needs with the device maker and keep a backup plan. This page is not medical advice. At the top of the published range, 590 W, the BLUETTI Apex 300 lasts 4.0 h of this routine, short of the 8 hour goal.

The 54 power stations in the data set, ranked smallest capacity first (the closest fit), then lower price, then lighter. Whether a link can earn us money never changes the order.
Enough Watts may earn a commission when you buy through links on this page. It never changes the math or the ranking.
A stationary oxygen concentrator runs its compressor nonstop: about 290 W at the typical figure in the data, from 200 W to 590 W depending on the model and its flow setting. That makes it one of the heaviest continuous loads a household plans for, 6,960 Wh a day.
The goal here is 8 hours. That alone takes 2,320 Wh usable, so 17 of the 54 stations are enough, all of them large. For a full day of nonstop use from one charge, 1 station is enough.
Plan for the gap, not only for the battery. Keep the backup oxygen your supplier provides, know how long it lasts at your flow rate, and confirm the power needs of your concentrator with the device maker. A station buys time; it does not replace that plan.
A portable concentrator on a pulse setting draws far less, and the question below works out the same 8 hours with one.
What size power station do you need for a home oxygen concentrator?
This setup uses 6,960 Wh a day. Lasting 8 hours takes 2,320 Wh usable, about 2,729 Wh of rated capacity at 85% efficiency. It also needs 290 W of continuous output.
Which is the smallest power station that is enough?
The BLUETTI Apex 300, at 2,765 Wh: 2,350 Wh usable gives 8.1 h of this routine. The ranking puts the smallest capacity first, then the lower price, then the lighter unit.
What about a portable oxygen concentrator?
With a portable oxygen concentrator in place of an oxygen concentrator (home, stationary), the setup uses 1,140 Wh a day and needs 95 W running. 48 of the 54 power stations are enough for 8 hours of nonstop use, against 17 for the setup above. The closest fit is the Goal Zero Yeti 500 (499 Wh).
