Comparing the Battery Life of Portable Oxygen Concentrators

When you need to rent a portable oxygen concentrator, the first thing you need to consider is how well it will meet your dosage needs, as prescribed by your doctor. You need a portable oxygen concentrator that delivers a continuous flow? Go for a versatile model, such as the DeVilbiss iGO or SeQual Eclipse, which are both portables that offer continuous flow settings. Only need a pulse dose? The Respironics EverGo or the LifeChoice will do the trick.

After your oxygen needs are met, check out how long the battery will last, how long it will take to recharge, and if you will be able to charge the battery while plugged into an outlet, so that you can continue using the machine.

Your concentrator battery needs will depend on where you plan to go with your oxygen concentrator, how many hours out of the day you will need it, and at which setting you need the oxygen as per your prescription. To help you choose the right portable oxygen concentrator for you, here are a few comparisons for different situations that might match your own.

Need Oxygen While You Sleep?

  • The lightweight LifeChoice features a special sleep mode that detects the changes in your breathing pattern while you're sleeping, to make sure you're still getting the oxygen you need during the cycle of inhalation and exhalation. With the internal battery and supplemental battery, you shouldn't have to charge for around 6 hours. The batteries will then have to charge for around 6 hours after that, however, but you will be able to plug it into an outlet and still use it if you need to. It has pulse dose settings from 1 to 3.
  • The highly versatile Oxlife Independence isn't as light as the LifeChoice, but is still light enough to carry with you wherever you go and has a built in cart handle and wheels. It offers a continuous dose between 0.5 and 3, which is best to use while sleeping, along with the pulse dose settings from 0.5 – 6. Plugging this in while you sleep is your best bet, as long as you have access to a power supply, but the battery will last 2.5 hours on it's own, but that's only if it is left on the highest setting.

Doing Some Strenuous Physical Activity?

  • In a test conducted in 2008, there were two proven best POCs to use during exercise – the first one is the EverGo by Respirionics. This one is also ideal for exercise because it has a battery life of 4 hours on the highest setting (pulse dose from 1 to 6) and it only weighs 8.5 pounds and has an operational elevation of 8,000 feet – you can go hiking with it in the mountains!
  • The second best POC for physical activity is the Inogen One G2, with a battery life of 3.5 hours on the highest setting. You can choose between the 12 cell battery model and the 24 cell – the 24 cell giving you more battery life, or course. It's also small and light, weighing only 7.25 pounds.
