CPAP machines are vital if you have sleep apnea, which is true for people who travel as well. The problem is that many CPAP machines can only be used with an AC outlet. Meaning they will need to be plugged in to a power socket. This isn't ideal for travel, so you want a version that has a good battery supply. Let’s talk about the best options in terms of the best battery operated CPAP machines that last the longest.

Considerations For Battery Operated CPAP Machines

As you probably know, a battery operated CPAP machine can end up being really expensive. You don’t want to go out and buy one that doesn’t suit your needs or preferences. When it comes to CPAP machines and batteries, there are a few important things that you need to consider.

Is It Only DC?

DC stands for direct current and it means that power only flows in one direction. Batteries are DC power supplies. You need to look out for CPAP machines that can only use DC power supplies (batteries) with a DC to AC converter. This is not ideal as you will need a converter, which adds bulk to the equation, plus it costs money too. Look for a battery powered CPAP that can handle a battery without this DC to AC converter.

Battery Integration

These CPAP machines are intended for travel, so you obviously want as small a machine as possible with as little weight as possible. Having an integrated battery is great for this. You can plug these machines in or you can use the integrated battery. Versions with inbuilt batteries usually use a simple power cord or USB cord for charging.

The Battery Life

This might be a bit of a no-brainer, but you do of course need to look out for the specific battery life of the machine in question. Some battery powered CPAPs can go for 8 hours and some for 13 – 15 hours. There are even ones that can actually last for several days without being charged. The better the battery the higher the price, but the less hassle involved for you.

Recommended Battery Operated CPAP Machines

Z1 Auto Travel CPAP Machine

The Z1 Auto Travel CPAP Machine is a pretty decent option to go with. Just like most other travel CPAP systems, this one does run on good old AC power, so you can plug it in whenever possible. However, it does also come with a special Power Shell that is perfect for those overnight camping trips or any other time when you might not have an electrical outlet handy.

You can easily get a full night of battery power out of the Power Shell. It should last for about 10 hours, which is more than enough time. On a side note, this Power Shell needs to be purchased separately and it will add more bulk to the equation as it is an external component.

Philips Respironics Dreamstation Auto CPAP

The DreamStation Go is another good battery operated CPAP device to go with thanks to its fairly good battery life. Yes, you can plug it in whenever you need to, just like all other CPAP machines, but it does also have a battery for those times when there is no plug to use. The battery is totally integrated into the system, so there is no external battery or power shell to deal with. It’s compact and thus convenient to travel with.

To charge the battery for this CPAP machine, simply use the integrated USB slot or cord that can be plugged into any power supply. This battery can last for a total of 13 hours, making it slightly more longer lasting than the Z1 Auto CPAP I spoke about before. This is definitely a convenient CPAP option to go with for travel, but a pricier one as well.

Transcend II Travel CPAP Machine

The Transcend II Travel CPAP Machine has probably the longest lasting battery of all. Now, you should be aware that there are two battery options to go with. One being an overnight option and the other being a multi-night option. Both of these batteries are sold separately, so you will need to pay a little extra. The batteries do not integrate directly into the machine. They need to be plugged in right where the power cord would usually go. This also adds a little more bulk and weight to the equation.

The overnight battery can last for 8 or 9 hours, which is pretty decent. However, the real standout aspect is the multi-night battery which can be used for up to 3 nights depending on the pressure setting you have the Transcend II on. All in all, the Transcend II CPAP has the ability to last the longest in terms of battery life, but with the purchase of a separate battery, thus increasing the price significantly.
