How Much Does a Portable Oxygen Concentrator Weigh (on Average)?

Portable oxygen concentrators are generally lighter and smaller than any other oxygen device. If you dive into the oxygen concentrator industry, you will find that the average weight is between 5 to 10 lbs. While a good chunk of portable units fall in this range, you wouldn't have trouble finding ones that are lighter or heavier. 

There are POC units under 5 lbs. They are the smallest of them and are typically travel-size. POCs heavier than 10 lbs are physically larger and commonly come with wheels or a cart. 

Portable Oxygen Concentrators Weight by Size

Portable oxygen concentrators are not a one size fits all scenario. Each unit is different and each model is unique. The size and weight differences of portable concentrators are related to the oxygen flow that it delivers and the battery life.

That is why stationary or home concentrators weigh more than POCs. It is also why they have longer battery life. If you start looking into various portable oxygen concentrators online, you will find that there are small, medium, and large concentrators. 

Small Portable Oxygen Concentrators

Portable concentrator units of the smallest size often weigh around 5 lbs. It is with or without external batteries mounted. While they are the most portable and mobile, keep in mind that they have the lowest oxygen capacity. It is not ideal for patients with high oxygen needs to settle for a small portable concentrator. 

Also, they tend to have shorter battery life. It would be wise to bring extra batteries just in case. 

Medium Portable Oxygen Concentrators

Medium-sized portable concentrators weigh between 6 and 10 lbs by themselves, or with the external battery mounted. They are physically bigger than small portable concentrator units and have higher amounts of oxygen capacity. They are still great for traveling and transport. 

Large Portable Oxygen Concentrators

Large concentrators typically weigh over 10 lbs. They have the largest oxygen capacity amongst portable concentrators. They also have the capacity to provide as much as 10 liters per minute.

Typically, a POC with this weight has continuous flow delivery options. There are a few who have dual-use or purpose, having both continuous and pulse dose delivery modes. 

These POCs often feature a convenient rolling cart or a strap system to make transport and travel more effortless. Large POC units have bigger compressors and batteries.

Why Is Weight Important When Buying a Portable O2 Concentrator?

Weight is a vital factor when choosing a portable concentrator, which is why it’s something that you will need to consider. Here are the benefits of buying a portable oxygen concentrator that’s light and easy to carry.

1. Mobility

Generally speaking, most are not satisfied with the weight of their oxygen device. These machines are undoubtedly heavy, which limits your ability to move freely. The more weight you carry, the more energy you exert — and ironically, you will need more oxygen to compensate for that. 

That is why weight should be a factor to look into. Since you need supplemental oxygen to manage your respiratory-related symptoms, you will need your oxygen device near you. That is not just possible with larger oxygen machines like oxygen tanks or cylinders. It hinders your mobility. 

2. Travel

If you have an active lifestyle and a love for traveling, you need a POC with the right weight. Dragging a heavy oxygen device is not just ideal if you are constantly on the road. Lightweight POC units are perfect for traveling around since you can carry them easily and pack them inside a suitcase.

3. Convenience

One of the main reasons people choose portable oxygen concentrators is due to the convenience they offer. Most portable concentrators do not need additional equipment like wheeled carts to bring them around. Since they are light, you can throw them inside your backpack or shoulder bag with no problem. 

4. Space

Large and heavy oxygen devices, like stationary oxygen concentrators, need space in your house. That is one of the unfortunate downsides of them. They are not easy to store and would stand out often. 

Since portable concentrators are small and lightweight, they naturally take less space. You can store them inside a cabinet or on top of a drawer. Even the heaviest portable concentrators do not need as much space as a home concentrator. 

5. More Freedom and Independence

The lighter the POC is, the more freedom and independence you have. With a light POC, you would not have much trouble carrying them around. May it be a walk to the park or a stroll in a mall. Patients with light POCs can lead more active and energetic lives.
