7 Best Portable CPAP Battery Backup (for 2020) – Reviews & Comparison
People use CPAP for different reasons, one of them being sleep apnea. Most of the CPAP (Continuous positive airway pressure) devices on the market are AC powered. So when there is no electricity or when you are traveling somewhere, it could be difficult. To mitigate such a situation, we can use portable battery backups. In this article, we shall see some of the best battery backups for CPAP devices. You’ll learn more about what to look while purchasing a CPAP battery and our best picks, which will help you make an informed purchase.
There are many reasons for wanting to use CPAP battery backup – one of the common ones being unreliable sources of electricity to run your CPAP machine. Other times it’s a busy travel schedule that takes you to off-grid places where sources of power are limited and inconsistent.
In other scenarios, people are remotely located, and lousy weather quickly brings down the power grid. Whichever the case might be, a CPAP battery pack can offer significant assistance in such inconvenient times.
Before looking at our seven best picks, the following information should help you get started.
Things to consider when buying a portable battery for CPAP
1. Battery Capacity
This has to be the number one consideration in choosing a battery for your CPAP machine. The battery life determines how long your CPAP device can be powered with the battery. For example, if your CPAP requires 50W of power and you have a 500Wh battery. In this case, your battery can drive your CPAP continuously for 10 hours. Similarly, if the battery rating is just 200Wh, the backup time will be 4 hours.
Off-grid locations require you to have machines that can sustain overnight functions, or at the very least, one that can last long on a single charge. Therefore, to secure yourself from significant disappointments and inconveniences, you must pay attention to battery life.
Typically, CPAP devices like Resmed consumes around 50W of power/hr
2. Power Capacity
As the battery capacity, the power output capacity of a CPAP battery is another significant consideration. The power capacity determines whether your battery can power your CPAP or not. For example, if your battery’s power capacity is 50W and your CPAP requires 55W, then the battery cannot power your CPAP.
Most backup CPAP batteries have a power rating below 100W. This means that the best option you have is buying one closer to or above the 100W power rating. With so doing, you’ll have an added advantage of extending the use-time with your CPAP machine. If you are planning to use this battery for powering gadgets like TV, Laptop, etc along with your CPAP, you should pick a multi-purpose portable power station.
The last but certainly not least consideration you should observe is the battery’s portability. Travelling already comes with so much lifting, and to add to your luggage might make you more frustrated.
Therefore, you need a portable CPAP battery to minimize the heavy lifting in your travel. More and more people are inclined to owning less bulky and sleeker CPAP machines. This goes without saying that they also prefer CPAP batteries capable of matching the same design.
However, in looking at portability, you must ensure that you pay close attention to the battery’s functionality.
Now that you have some significant knowledge of what to consider before buying a portable battery for your CPAP machine let’s look at the products.
Our Best CPAP Battery Picks
While choosing the power stations, I made sure all of them are suitable with almost 95% of CPAP devices including Resmed, Philips, DeVilbiss, etc. Also, I have picked the batteries of different ranges from 200Wh to as high as 500Wh. This is to make sure that the backup time will be at least a day.

Also, choosing a power generator of higher wattage (say 300W) will let you use the battery for powering many other electronic equipments. For example, if you own a 300W battery station, it can not only power your CPCP but also your laptop, TV, electric bulbs, etc.

Now that you have seen the best battery backups for your CPAP device, it is time for my final advice. If I place myself in your shoes, I would go with either Rockpals 300 or Bluetti AC50. Rockpals is an amazing budget-friendly option. Bluetti is packed with so many good features but it is slightly expensive. If you are looking for multipurpose use (including CPAP), Bluetti AC50 is a good option. If I am very tight on budget, I would go with Acopower. It is a basic battery backup but it can do the job. Jackery 240 and Aeiusny are very good alternatives but are slightly expensive. Renogy is quite advanced and may not be suitable for everyone. If you need more ports, going with Renogy makes sense. Goal Zero has an aesthetic design but it is super expensive when compared to others. I would avoid it.
