Portable CPAP power – even with a humidifier!

The Atom Pro is the second generation of portable power stations from Powapacs, and is ideal for powering your CPAP machine on your travels. The integrated Lithium-Ion battery makes the Atom Pro a compact power station weighing just 2kg, allowing almost all electrical devices up to 150 watts to be run from it. With a battery capacity of 312 Wh and both 12V DC and 230V AC sockets, the Atom Pro is suitable for powering any CPAP machine – even when using a humidifier!

Please be aware that the high capacity of this battery mean it will be too large for most airlines to accept on board – either in the hold or your hand luggage. If you need to take a battery pack on a flight, please consider the smaller, flight-friendly Powapacs ION Battery Pack.

Most battery packs have a 12V output only – which is great for most CPAP machines as often the manufacturer will produce a 12V cable. However not all machines have a 12V power option – and if you’re using a heated humidifier, then a 230V AC power supply is the only option. The Atom Pro does both.

Estimated running times

When powering a CPAP machine (without a humidifier) via a 12V cable, the Atom Pro’s huge capacity means you can expect up to a weeks’ worth of power on a single charge, depending on your particular CPAP machine and pressure requirements. Here is a table of estimated run times using a 12V DC connection with no humidifier:

CPAP Machine5cmH2O10cmH2O15cmH2O20cmH2O
ResMed AirSense 10 (all)28 hours20 hours17 hours12 hours
ResMed S9 AutoSet / Escape25 hours22 hours19 hours17 hours
ResMed S8 AutoSet / Escape25 hours23 hours15 hours13 hours
Philips REMstar 60 Auto / Pro60 hours40 hours29 hours23 hours
DreamStation Auto / ProTBC35 hoursTBCTBC
DeVilbiss SleepCube AutoAdjust Plus / Standard Plus55 hours39 hours29 hours21 hours
Transcend 3 Auto140 hours80 hours45 hours33 hours

The above times are estimates only, and are not guaranteed. Actual running times will vary based on multiple factors including machine, pressure setting, altitudes, mask leakage, exhalation relief, and more. When charging the Atom Pro, it takes approximately 5-6 hours to go from 0% to 100% using the mains charger.

If using the 230V option, run times will be reduced as this is a less efficient way of getting power from the battery to the machine. Running times will be around 70% of the estimates above – so we do recommend using the appropriate 12V cable for your machine rather than the mains lead where possible.

If using a humidifier – run times will be significantly less than the times above. Heated humidifiers use a lot more electricity than a CPAP machine by itself. Running times will be around 20-30% of the estimates above – in most cases still enough for a couple of night’s use per charge. Before the Atom Pro, the only real option for portable power with a humidifier was a bulky, heavy deep-sea battery. Now it is much easier to continue to benefit from humidified CPAP therapy while on the move.

Another option worth considering for short-term use is a Waterless Humidifier. These are small filter-type devices that sit between your mask and tube, recycling the humidity from your exhaled breath. This provides a good level of humidification without needing a heated humidifier, meaning you will be able to get considerably more hours use from your Atom Pro. Each Waterless Humidifer lasts for three nights before needing to be replaced, making them an ideal short-term solution. You can find out more about those here.

Which 12V cable do I need?

We recommend using the appropriate 12V power adapter to connect this battery to your CPAP machine, which will provide greater efficiency (and therefore run times) than the mains lead. Intus provide most of the appropriate cables, which you can find below:

*Please note ResMed state that their cables are “not for aircraft use”. Please bear this in mind if planning to use your ResMed machine on a flight. We suspect that means not to use the cable directly into the aircraft power supply should there be a socket available at your seat, as it is difficult to see why you would not be able to use it with an independent battery source such as this one. However the wording on this note is unclear and we would strongly recommend seeking clarification from ResMed and your airline as to whether or not it will be OK to use this cable on a flight with an independent battery pack rather than the aircraft’s power.
