What Size Generator Do I Need for An Oxygen Concentrator?

Patients with asthma as well as those recovering from surgery or other medical conditions, frequently use oxygen concentrators.

Concentrators not only deliver oxygen to patients but also remove carbon dioxide, preventing potentially life-threatening cases of hypercapnia (also known as "over-breathing"). To accomplish this, they filter the oxygen out of the surrounding air and turn it into a liquid, which is then kept in a tank nearby.

Oxygen concentrators' energy needs are between 75 and 300 Wh, depending on the type. An oxygen extractor can be powered by a generator producing between 600 and 1400 watts. You should search for a generator with at least 700 watts of continuous output capacity if you intend to use it solely to power your oxygen concentrator. A gasoline-powered generator is the best bet because it is silent, lightweight, and simple to maintain. Instead, solar-powered generators could be a choice if you're concerned about your impact on the environment.

This is a significant part of the above discussion, and it's the day's topic. You may be wondering what an oxygen generator is at this point. It's different than we have any reason to use it. I need clarification as to its function. Finally, why do we need an engine for it in the first place?

So, you could use a small generator that you can keep inside to power an oxygen concentrator. And you might have some questions which we, as a WireQuality team, tried to answer here.

How Oxygen Concentrator Works ?

Air contains 21% oxygen and 78% nitrogen; an oxygen concentrator removes the nitrogen, leaving only the oxygen, which is then compressed and put into a tank for patients to use. Oxygen concentrators, whether stationary or portable, can be powered by both mains electricity and batteries.

What is the best generator for an oxygen concentrator?

Medical emergencies can happen at any time. All you need to do is be ready. And making sure your oxygen concentrator keeps running when the power goes out is one of the most important things you can do to be ready.

You can run extension cords from other rooms in your house or even from your neighbours' homes, but that isn't always convenient or safe. You need something small and reliable that will keep your oxygen concentrator running as long as possible. This is where the A-iPower Portable Inverter Generator, 2000 Generator comes in.

Can I use an inverter generator to power an oxygen concentrator?

You need to know how to keep an oxygen concentrator running if you have one.

You know that the last thing you want is for the power to go out. But what happens if they do? What other options do you have?

In fact, many companies that make medical equipment say that your home or business should have an inverter generator. In the event of a power outage, an inverter generator can keep on giving power, and it can run devices like oxygen concentrators without any problems.

What Size Generator Do I Need for An Oxygen Concentrator - Inverter Generator

Still, it's important to find an inverter generator that fits your needs since not all generators are the same. You need to make sure that your generator can handle the load that your equipment is putting on it. For example, an oxygen concentrator uses between 75 and 300 watts per hour. If you want to buy a generator but don't know how much power it will give you, check the specs on the product page or call customer service before you buy!

But in general, an oxygen concentrator can be powered by any inverter generator with a power rating of at least 600 watts. And a gasoline-powered generator is a great choice if you want a generator that can handle the occasional power outage and the occasional use of your oxygen concentrator.

How many watts does an oxygen concentrator need to function?

When powered by 120 volts, most common oxygen concentrators consume four amps. The oxygen concentrator requires about 480 watts of continuous running power from its motor.

Do I Need Special Wiring to Join an Oxygen Compressor to a Generator?

If you're using a portable oxygen tank, you'll need to plug it into a power outlet.

Oxygen Concentrators and Backup Battery?

The typical oxygen concentrator does have a reserve battery that keeps it going for up to 20 minutes.

An "inverter generator," which produces a cleaner waveform, is preferable when powering electrical devices. While inexpensive non-inverting kinds may function normally in appliances like refrigerators and kettles, they may malfunction in computer and microprocessor-controlled medical devices.

This option is more expensive than a regular gas or diesel engine, but it is much better for protecting delicate machinery.

Fridges have a greater starting current than when they are running, so additional capacity is needed when running multiple appliances at once.

There is not much of a burden on oxygen concentrators because of the small pumps and the molecular sieve column swapping control. The dialysis equipment is a pump, which raises questions.

When using an oxygen concentrator, what size inverter should I use?

To operate your oxygen machine, you must have a TRUE SINE WAVE POWER INVERTER. Depending on your prescription, many oxygen devices require up to 1500 watts of sine wave power.

Modified sine power converters are not safe for oxygen concentrators and can cause them to malfunction or even break.

Can you use an extension cord with an oxygen concentrator?

High concentrations of oxygen are extracted from ambient air using energy in an oxygen concentrator. It's best to keep your concentrator away from extra cables to avoid any potential accidents. Lighter than a standard home unit, a portable oxygen concentrator can be powered from a 12-volt outlet in your motorhome or tow car.

The oxygen generator can be left on all night if necessary.

Leaving the oxygen generator on overnight: safe? Yes. Those who have breathing difficulties or a respiratory disease can safely leave their oxygen concentrator on all night. Still, you should make sure the generator will last all night by checking its capacity.


A generator is a smart way to make sure that a patient's oxygen concentrator keeps running even when the power goes out.

To figure out what size generator I need for an oxygen concentrator, I do need to give it some thought.

You should now know about real-world factors and be ready to act.
