The short answer: yes, for power. A home oxygen concentrator typically draws 300 to 600W, far under what a Jackery HomePower 3000 can supply, and its 3,072Wh of battery runs a 400W machine for about seven to eight hours. A portable concentrator uses a fraction of that and runs for days.
The HomePower 3600 Plus and the Solar Generator 5000 Plus stretch it further. A word before the tables: this is equipment people depend on, so the section on safety below matters as much as the arithmetic. This page is general information, not medical advice.
What medical equipment actually draws
Wattage varies a lot by model and by flow setting. These are typical ranges; the label or manual on your own machine is the figure to trust.
| Device | Typical draw |
|---|---|
| Home oxygen concentrator, 5 litre | 300 to 450W |
| Home oxygen concentrator, 10 litre | 500 to 650W |
| Portable oxygen concentrator (charger) | 40 to 90W |
| Nebulizer | 50 to 100W |
| Hospital-style adjustable bed | 100 to 200W while moving, near zero at rest |
| CPAP with heated humidifier | 40 to 90W |
| Mobility scooter or wheelchair charger | 100 to 300W |
| Phone and tablet charging | 10 to 20W |
Many of these run only part of the time, so a day’s energy is often lower than the nameplate suggests. A concentrator is the exception: it runs continuously.
How long it runs
The table assumes the machine runs constantly and counts the battery alone, with no solar. It ignores conversion losses, so real runtimes are roughly 10 to 15 percent shorter.
| Equipment | Draw | HomePower 3000 (3,072Wh) | HomePower 3600 Plus (3,584Wh) | 5000 Plus (5,040Wh) |
|---|---|---|---|---|
| Portable concentrator charger | about 70W | about 44 hours | about 51 hours | about 72 hours |
| 5 litre home concentrator | about 400W | about 7.7 hours | about 9 hours | about 12.6 hours |
| 10 litre home concentrator | about 600W | about 5.1 hours | about 6 hours | about 8.4 hours |
Two things stand out. A home concentrator drains a battery quickly because it never stops, so one battery is hours of cover, not days. And a portable concentrator is a very different load, which is why many households keep one as the long-outage plan and use the big machine only when the power is on.
Stretching the hours
- Switch to the portable concentrator for the length of the outage if your doctor and supplier agree it meets your needs. It cuts the draw by around 80 percent.
- Recharge with panels. A bright day returns 1,500 to 2,000Wh with a typical panel set, which is another three to five hours of a 400W machine. Our guide to how many panels charge a HomePower 3000 shows the charge-time sums.
- Keep everything else off the battery. Run lights and phones from small devices and keep the fridge to a minimum while the concentrator runs.
- Charge fully before a forecast storm. Plug the unit in whenever bad weather is coming, so it starts full.
Safety steps to settle before an outage
This is the part to do on a calm day, not in the dark.
- Ask your equipment supplier or doctor whether your machine can run on a battery generator, and what to do if it cannot.
- Keep the backup cylinders your supplier provides, and know how long they last at your flow setting.
- Register with your utility as a customer who relies on medical equipment. They keep a list and some send advance warnings.
- Test it now. Switch to the battery for an hour on an ordinary day and check the machine behaves, the alarm does not trip, and you know where everything plugs in.
- Keep a plan B. A neighbour, a relative with power, or a nearby hospital or shelter, written on a card by the machine.
- No flames near oxygen. Keep the concentrator and tubing well away from candles, gas stoves and smoking, which matters more in an outage when people reach for candles.
Battery generator or gas generator?
For medical equipment the choice is usually clear. A gas generator has to run outdoors because of carbon monoxide, needs refuelling through the night, is loud, and takes a few seconds of attention when you may be least able to give it. It can run longer, but it asks a lot of the person using it.
A solar generator is silent, sits beside the bed or chair, has no exhaust, and switches on without a pull cord. Its limit is runtime, which is why it pairs best with panels and a backup cylinder. Our solar generator versus gas generator page covers the trade-offs in full.

Which unit to buy
For a portable concentrator, nebulizer, CPAP and phones, the HomePower 3000 is more than enough, with days of cover and plenty left for a fridge. Our CPAP guide works the overnight sums.
For a home concentrator that runs all day, runtime decides it. The 5000 Plus gives the most hours, about 12 on a 400W machine, and the panels carry on from there. Our sizing guide shows how to add medical equipment to the rest of your list, and the home backup buying guide lays each unit out against it.
