Best Portable Power Pack for CPAP Reviews

1. MAXOAK Portable Power Pack

The MAXOAK Portable Power Pack is my best overall pick when considering the best portable power pack for CPAP.

This easy-to-carry and lightweight battery is specifically made for use with CPAP machines. It’ll power your CPAP machine for those nights out camping without access to power outlets and is also a trusty backup power source if you’re stuck in a power outage.

As for the top features of the MAXOAK Portable Power Pack, you’ll get:

  • An incredible capacity of 297Wh, making it the most powerful battery of the ones recommended here. This will get you multiple nights of power for your CPAP machine.
  • As for the specific battery life, you’ll get 40-50 hours for most CPAP machines with the humidifier/heater off and a low pressure setting.
  • Two charging options: with the included AC adapter that plugs into the wall and it can also be charged with a car charger (a DC 12V to AC car converter is required and not included with purchase).
  • A short charge time of just 5.5 hours.
  • Three DC outputs (12V, 15V, and 24V) designed for a variety of CPAP or BiPAP devices with various voltages.
  • A fast-charging 2.5A USB port for 5V USB-powered devices such as your smartphone or tablet. This is an extremely handy feature to have in case you need to charge your phone for an important or emergency phone call while camping or in a blackout.

Due to the high capacity of the MAXOAK Portable Power Pack, it’s important to note that it’s not TSA-approved. The capacity of the battery is too high to be able to take it with you on flights.

However, the MAXOAK Portable Power Pack will certainly be your reliable power source for long roadtrips to power your CPAP machine and charge your phone for your camping adventures.

What comes with the MAXOAK Portable Power Pack:

  • 1 AC adapter charger

Portable Power Pack for CPAP Buying Guide

Below I’ve outlined the key features for you to consider to help you decide which product is best for you. Once you have a good understanding of these features, take a look at my table at the end of this section to help you compare the features across the products.

CPAP Specificity

CPAP batteries are recommended over universal batteries since they’re specifically designed for CPAP machines. The universal batteries, however, will still work for powering your CPAP machine (and are some of the most powerful batteries recommended here) and come at a lower cost.

Battery Life

The battery life of these devices will vary depending on the type of CPAP machine you have, pressure setting, use of humidification, use of heated tubing, altitude, and many other factors.

FAA/TSA-Approved

There are specific regulations on the Wh of a lithium ion battery that you can carry with you on a plane. This is something to consider if you need to fly with a portable battery.

Dual Battery Capability

This is the ability to have two batteries connected to power your CPAP machine for a longer period of time. The Battery Power Solutions Freedom Portable Power Pack is the only battery with this capability.

This is definitely something to consider if you want a battery that you can take with you on a plane but also need a longer battery life to spend more nights out camping.

Use as Battery Backup Power Supply

Not only are these batteries excellent sources of power when you’re away camping or away from home, but they can also be a reliable backup power source during a power outage. I highly recommend keeping one of these at home for this reason.

Charging Options

Depending on where you plan to use the battery, something to consider is your options for charging it. Some of these batteries can be charged in your car or using solar panels in addition to the standard AC charger you plug into the wall.

Battery Life Cycles

One battery cycle is the time from a fully charged battery to a fully discharged battery. The number of battery cycles tells you how many of these charging life cycles the battery has until it needs to be replaced.

Helpful Portable Power Pack for CPAP Tips

  • Check CPAP compatibility: don’t use the battery if your CPAP machine isn’t compatible with it, as this can damage the device or battery.
  • To prolong charge time: use your CPAP machine without humidification, on a low pressure setting, and at a low altitude if possible. Also, keep in mind that powering multiple devices at once will decrease the run time of the battery.
  • Consider if you need to fly with your battery: According to the Federal Aviation Administration (FFA), lithium ion batteries including power banks must be carried in carry-on baggage only. The Wh limit per lithium ion battery is 100 Wh. There is no quantity limit for most batteries. Also, with airline approval, passengers can also carry up to two additional lithium ion batteries of 101-160 Wh.
  • Avoid: charging the battery while powering devices at the same time.
  • Safety precautions: don’t get the battery wet or expose it to extreme heat or fire.

Best Portable Power Pack for CPAP Summary

maxoak cpap battery backup

Overall, you see that the MAXOAK Portable Power Pack is my number one pick. It’s specifically designed for CPAP machines and is an extremely powerful battery that will last you many nights out camping or provide a trustworthy backup power source in case of a blackout.

However, if you need a battery that you can take on a plane, then I recommend the Medistrom Pilot-24 Lite Portable Power Pack. The Battery Power Solutions Freedom Portable Power Pack is another excellent CPAP-specific option here that comes at a slightly lower price.

Finally, if cost is the most important factor to you, then either of the universal batteries (the Renogy 72000mAh/266WhPortable Power Pack or Flashfish EA150 Portable Power Pack) are great. Remember that since these batteries aren’t specifically CPAP batteries, you may run the risk of damaging your CPAP machine.

Hopefully you found this review and buying guide helpful, and now you can easily decide which is the best portable power pack for CPAP for you.
