5 of the best portable batteries for CPAP machines

portable power supply for cpap machineA dependable backup power supply for your CPAP machine can be a literal lifesaver. Some of the scenarios that require portable power banks for CPAP machines are:

  • Power outages or blackouts. Although not very common, these events can last for a few minutes or a few hours, but sometimes even a few days.
  • Being in transit. Such as having to sleep during a flight, on a bus, or on a train.
  • Camping. With the right power supply, sleep apnea patients can enjoy the big outdoors too!

This is why we put together a list of some of the best portable power banks that can supply steady power to your CPAP machine until regular power becomes available again.

The MAXOAK CPAP Battery Backup has been specifically designed for powering CPAP Machines, which is why it’s compatible with a wide variety of them: Resmed Airsense/Aircurve 10, Resmed S9, Dreamstation, System one, HDM Z1(12V only), Transcend Mini, Airmini.

With a listed capacity of 297Wh, you can expect anywhere between 35 to 50 hours of continuous power or the equivalent of 5-6 nights. Of course, the actual duration can vary according to your actual CPAP machine power consumption.

It can be charged via a regular wall outlet, or even using a DC car plug, but in this case, you’d need a DC to AC converted, which is not included with the product. Furthermore, it should be noted that due to the high capacity this backup battery cannot be taken on planes, as it exceeds the 100Wh limit imposed by the FAA and TSA.

  • One DC output port
  • Two USB-A output ports
  • One car lighter output
  • Ergonomic and portable design
  • Weight: 44.6 ounces

The Renogy 72000mAh Laptop Power Bank with 12V Socket is a small but powerful and reliable back up for CPAP machines, despite not being mainly designed for it.

Thanks to its 12-volt DC cigarette lighter-style plug, it can be used to power devices that are bigger than a power bank, meaning it’s compatible with CPAP machines. Besides, its capacity of 72000mAh/266Wh is so powerful that it can work for 35 hours on a single charge with a CPAP pressure of 14 lb, the equivalent of 4 good night’s sleep. Sadly, no adapter is included, so you’ll need to buy one for the respective CPAP machine.

Recharging this portable charger is done via a DC pin, taking up to 8 hours, but thanks to its pass-through charging technology, there’s no need to disconnect it from the CPAP machine and wait until it’s full. Unfortunately, you cannot take this portable charger on planes, not even with special permission, as its 266Wh capacity is well above the 100Wh limit imposed by the FAA and TSA.

The Jackery Portable Power Station Explorer 500 is a monster of a backup battery. With a huge 518Wh capacity, it can power your CPAP machine for anywhere between 23 and 40h. But some users reported it lasting for about a week of daily use without needing a recharge.

One important feature of this portable power bank is the fact that it comes with 3 different DC output ports. Two regular ones and a car lighter port. This means that you can hook up to 3 different DC machines to it simultaneously. Actually 4 if you also count the AC plug, but this is less efficient than the DC ports, so using it will drain the battery faster.

The Anker Powerhouse 200 is a multi-use portable power generator which among many other things, can power CPAP machines. This device gives you the option to power your CPAP either via the AC outlet or via the DC car outlet plug. If your device cannot connect directly to the car outlet, you can use an adaptor, which you need to purchase separately. Charging your CPAP machine via DC might be less energy-intensive and might prolong the use time of your machine. Read our full review on the Anker Powerhouse 200.

5. BiXPower BP90 Portable CPAP Battery

BiXPower BP90 X2 High Capacity (96 Wh x 2 = 192 Wh)

  • Weight: 2.9 pounds

The BiXPower BP90 is the best portable CPAP power bank for travel. It seems to be made especially for taking advantage of the TSA and FAA rule regarding taking batteries on board. This rule specifies that the maximum Wh that can be taken on a plane is 100Wh and a maximum of two <100Wh batteries can be accepted per person. The BiXPower BP90 with its two dedicated batteries of 96Wh and a total capacity of 192Wh, comes just under the maximum capacity allowed on board.

These batteries are made specifically for AirStart 10, AirSense 10, and AirCurve 10 produced by ResMed. However, they should also be compatible with basically any 24V CPAP machine, but some dedicated connectors might be required in this case.

What to look for in a power bank for your CPAP sleep apnea machine

CPAP machines are medical devices that are used for treating various respiratory-related diseases. Although they are also used in intensive care units too, their most common use case is in treating sleep apnea, which a lot of people suffer from. In fact, as many as 20 million people have this condition in the USA alone, a big part of which are not even aware of it. Many sleep apnea patients have their own CPAP machines by their bedsides and they use them on a daily basis.

However, there are some cases where the CPAP machines cannot be powered from a regular wall-outlet anymore and they need an alternative power source. This is where portable power banks can help provide the needed power until an outlet becomes available again.

It’s highly important that you make sure that the backup battery you want to order is a good fit for your personal CPAP machine. This is why you need to do some due diligence before buying any portable charger, but also after it arrives at you. Here’s a quick checklist:

  • See if the power bank battery is specifically compatible with your CPAP machine model. Some batteries list all compatible sleep apnea machines in their product review
  • If you can’t find your model listed on the battery specifications, then make sure it can supply the exact power you need for your machine. Most CPAP models are powered by either a 12V or 24V supply.
  • Check if you don’t need any other extra equipment. In some cases, you may need to purchase a power inverter or an adapter in order to be able to connect your CPAP machine to the backup battery.
  • Once you receive your battery, test it right away! Don’t wait until you actually need it. Make sure it fits your machine and that everything works accordingly. If for some reason, you cannot make it work, then return the battery and look for a more suitable power bank
