Top 5 Portable CPAP Power Generators : Comparison of 200-1000 Watt Picks

Best Portable CPAP generators, CPAP (Continuous Positive Airway Pressure) is a medical device that helps sleep apnea patients to breathe more comfortably while asleep. It increases air pressure in the user’s throat to keep the air passages open while sleeping.

What is Sleep Apnea?

Sleep apnea is a severe sleeping disorder characterized by the repeated stopping and continuation of breathing while sleeping. There are different symptoms and types of sleep apnea. To read more about sleep apnea, you can click here. A CPAP machine is the best treatment for sleep apnea.

Why buy a generator for a CPAP Machine?

When you are at home, you can use your home electricity to power up your CPAP machine. However, when you are outside or traveling, you cannot always find an electric source to run your CPAP machine. What will you do when the power goes out for a long time? Why limit yourself indoors when you can enjoy camping, boondocking, and off the grid living? You don’t need to worry, as you can use a generator to power up your CPAP machine. With the right CPAP generator, you can not only power up your CPAP machine, but you can also use it to run a TV, cooler, ice shaver, coffee maker, or any other appliance in its power range.

Some Pre-requisites before buying a CPAP Machine

The most important thing to check before buying a CPAP machine is its ability to power your CPAP machine. You must also look at the backup time and number of CPAP machines it can manage. Ensure that the generator you intend to buy can be charged through various modes such as AC power, solar panel, generator, and a car outlet. It must be easy to carry and store. We have discussed these features in detail and other qualities you must look for in a CPAP machine in this review’s buying guide section.

Buyer’s Guide

Users must have to consider the following factors at the time of purchasing the best CPAP generators.

Compatibility

First of all, check if the CPAP generator is compatible with the CPAP machine you have. Compatibility is one of the most important things to consider when buying a CPAP generator. Many CPAP generators are compatible with 90% of the CPAP machines, but it is still necessary to check.

Power Needs

The next thing to consider is your power needs. If you plan to run any other appliances along with a CPAP machine, take their wattage into account. Generally, people use phone/laptop chargers, coolers, and devices with 100-150 watt power on a CPAP generator. It is better to have a cushion of extra power when it comes to a CPAP machine generator.

Pure Sine Wave

A CPAP machine is a sensitive medical device; hence, it needs pure sine waves. Inverters with modified sine waves are not advisable for CPAP machines. So, make sure you are buying a generator that produces pure sine waves.

Battery Capacity

A CPAP generator with a higher battery capacity can power your medical device for a long. Take an example of Jackery Explorer 500 that comes with a battery capacity of 518Wh (watt-hour). This generator can easily power a CPAP machine for up to 5 nights. But if you are a traveler and go on long trips, then a generator with a 1000Wh battery capacity would be ideal for you.

Portability

To power your CPAP machine outdoors, you must need a portable generator. This article has all the lightweight and compact generators that are easy to lift and move.

The lightest CPAP generator is the FlashFish EA150 that only weighs 4.5 pounds.

Power Outlets 

Many CPAP machines operate on both AC and DC voltages, so it is up to you to either uses a 110V AC plug or a DC plug to power your medical device.

If you have a 24 Volt CPAP machine, make sure your CPAP generator features a 24 Volt outlet. Or, if you own a 12 Volt CPAP machine, make sure you are selecting a generator having 12 Volt ports.

Battery Management System

Battery Management System is the most useful feature of CPAP generators that protect numerous factors beyond our control.

It gives over-voltage protection, low-voltage protection, overheats protection, and over-current protection, along with short-circuiting protection and lock-on protection.

Display

When you have a generator with a fully loaded display, it becomes easier to use it. The latest models tell you about battery percentage, recharging status, and power is drawn.

Warranty

All the CPAP generators on our list are of high quality and will not create any problems soon. However, a warranty adds value to your purchase and gives you peace of mind. In case of any unfortunate event, you have a warranty to claim and get your generator sorted out.

Price

A basic CPAP generator will not cost you much. However, if you want more power and the latest features, you will have to pay more. We suggest you never compromise on quality as it is critical for your wellness.

FAQs

How much power does a CPAP machine use?

Before purchasing a CPAP generator, it is necessary to determine how many watts your CPAP machine uses. Most of the CPAP machines use 30 to 60 watts of power, so make sure you are buying a generator that can produce more power than the CPAP requirement.

How can I calculate the backup time for my CPAP device?

You can find out the backup time with the help of a simple formula given below.

Backup Time: Generator Power Output*0.8/CPAP Machine operating Power

For example, your CPAP machine’s operating power is 60 watts, and the generator has a power rating of 500 watts. The backup time will be 6-7 hours. For a CPAP machine with 30 watts of power, it will be 13-14 hours.

How to lower the power rating of my CPAP machine?

You can reduce the power drawn by your CPAP machine by removing the humidifier part of the CPAP machine. Only do this if you can manage without it. Secondly, you can use a DC adapter instead of an AC adapter to conserve power and enhance your generator’s backup time.

What other devices a CPAP generator power?

Other than a CPAP machine, the generator can power any device falling under its rated power limit. They will be mostly small appliances like mobile/laptop charger.

Can a single generator power 2 CPAP machines?

Yes. If the generator has more than one CPAP plug output, it can power 2 CPAP machines. Please keep in mind that the backup time will be half for both machines.

Can I take my CPAP generator/machine on a plane?

A CPAP generator is not allowed on a plane. However, there is no restriction in taking a CPAP machine along with you.

What care should I take for my CPAP generator?

Always keep your generator in a dry place away from water and snow. Make sure it is kept under the shade and not exposed to sunlight. If you plan to store your machine for a long time, ensure that it is completely charged and check it periodically.

What are the advantages of using a solar generator for CPAP?

Advantages:

A solar generator serves as a handy power bank during outdoor trips like camping, hiking, and others. There will be no need to find electricity hook-ups in campsites to power your CPAP. Also, during emergencies like power outages caused by natural disasters having a solar generator is quite useful.

Solar generators are highly portable because they are light in weight and have a compact design. So, as a traveler, you can easily carry them anywhere with ease.

  • Solar generators don’t require fuel to run, so it is an eco-friendly option for CPAP users.
  • They are energy-efficient as well.
  • You can recharge the solar generator battery via a carport or an AC wall outlet.

What type of solar panel is best to use for a CPAP generator?

Solar panels collect solar energy and convert it into electricity. But crystalline solar panels are different from amorphous panels.

Crystalline solar panels are more efficient in collecting and converting electricity as compared to amorphous solar panels. They are further divided into polycrystalline and monocrystalline panels. But these crystalline panels are quite expensive. So, if you don’t have enough budget for a crystalline panel, then an amorphous panel is the only option for you.

Conclusion

Now that you know everything about a CPAP generator, you can select one from the list above and make your life easy. Don’t compromise on your outdoor trips if you suffer from sleep apnea because a portable CPAP generator is there to help you.
