Best Portable Power Stations For CPAP in 2022 Reviewed

-

A CPAP machine (Continuous Positive Airway Pressure) is the most common treatment for sleep apnea. Sleep apnea causes interruptions or pauses in breathing due to a temporary blockage or obstruction in the throat.

A CPAP machine sends a steady flow of pressurized air. It helps people with sleep apnea breathe easier, in addition to lowering blood pressure and reducing the risk of stroke, diabetes, and headaches.

The only downside to a CPAP machine is that it relies on a constant power source throughout the night to deliver continuous airflow to the sleeping person. Frequent power outages or living off the grid make it challenging to receive a reliable air supply.

This is where a portable power station (PPS) comes in, so you can have backup power when you need it most. Find the best portable power stations for CPAP machines in 2022 to ensure a restful and healthy night’s sleep.

What to Look For When Buying Portable Power Stations for CPAP

Battery Capacity

Battery capacity is the most critical factor when buying a PPS for a CPAP machine. The capacity of any PPS relates to how much energy it can store, which determines how long it can supply backup power. 

Battery capacity goes hand-in-hand with your CPAP machine’s wattage usage. You need to know how many watts your CPAP machine uses to purchase an appropriate PPS.

Most CPAP machines require between 30-60 Watts. Your machine’s specific power intake should be listed on the device, in the manual, or readily available online. The energy use calculation will often be in ampere-hours, so you may need to convert it into watt-hours.

The calculation is simple: Amps x Volts = Watts.

Once you know the watt usage of your CPAP, you can multiply that by the number of hours you’ll be asleep.

For example, suppose you have a 60 Watt machine and want to sleep eight hours. You’ll multiply 60W x 8 hours = 480 watt-hours. 

The 480Wh is the minimum capacity you need to look for in a PPS. All the PPS units reviewed here have more than enough capacity to run your CPAP machine. 

Multi-Device Functionality

Remember that you may also want to run other appliances or devices from the power station in addition to your CPAP machine, particularly in the event of a power outage or if you are living off-grid.

The best solution here is to look for higher capacity PPS units that offer multi-device functionality if you intend to hook up multiple appliances and devices. 

Portability

A compact and lightweight PPS will be easy to move around to different rooms in your home.

Portability is paramount if the CPAP machine is necessary for someone with additional health problems. They may sleep during the day and not have a settled night-time routine.

Portability also makes it easy to take the PPS with you when you travel, giving complete peace of mind that the CPAP machine will have an uninterrupted operation regardless of location.

Charging Options

Choose a portable power station with the widest range of power sources so you can charge from a wall outlet or even use the traditional DC car port for off-grid vacations. 

Hybrid charging ensures you are never left vulnerable. Regardless of location, you should always be able to recharge your portable power station ready for use.

With EcoFlow PPS units, you can also take advantage of solar charging. Simply attach solar panels (sold separately), and you can transform your PPS into a portable solar generator. Or, save yourself money and purchase a PPS + solar panel bundle with the EcoFlow solar generators.

Accessories

You can add additional battery packs to expand the capacity. Expandable capacity gives you the best of both worlds: a compact and portable unit for regular use and the peace of mind that you have a fully charged additional battery ready if and when you need it.

EcoFlow Smart Batteries

EcoFlow smart batteries let you double your runtime. With the EcoFlow DELTA Max Smart Battery, you can boost your capacity and obtain additional portable power. Add up to two extra batteries to your DELTA Max and achieve a whopping 6048Wh capacity!

Plus, with EcoFlow’s smart home design, you can integrate the extra battery with your home wiring system and enhance your emergency power solutions. Now that’s a power solution that lets you breathe a sigh of relief. 

Why Do You Need a Portable Power Station for a CPAP Machine?

A CPAP machine is the most commonly prescribed device for sleep apnea, which currently affects around 22 million Americans

Sleep apnea’s negative impact on health is well documented, and a reliable power supply is vital to ensure smooth and uninterrupted operation. 

CPAP machines also support oxygen levels in hospital patients with respiratory problems. CPAP machines used after admission can help keep patients oxygenated at a level where a ventilator would not be necessary. 

A portable power station offers peace of mind to protect against many factors, including power outages, defunct outlets or faulty wiring, failing infrastructure, and lack of power access in remote locations. 

Power Outages

Even in locations with a good power supply, severe weather events can cause grid outages. And due to climate change, severe and disruptive weather is becoming more and more frequent.

Severe weather is the leading cause of power cuts in the US, according to Energy.gov data.

Climate Central reports that weather-related outages will only increase as the world’s weather pattern becomes more unpredictable and prone to extreme events.

There was a tenfold increase in significant power disruptions between the mid-1980s and 2012 in America. US power outages have doubled in the last twenty years.

Even when blackouts aren’t the issue, other problems like faulty wiring or broken outlets in the bedroom can prevent a reliable power supply. 

Thankfully, with robust solutions like the EcoFlow DELTA Max, you can supply reliable energy no matter the weather or the condition of your home wiring.

Ageing Power Network

It’s a perfect storm—the weather is getting worse just at the time the country’s aging infrastructure is starting to break down.

Old infrastructure, lack of investment, and increasing demand do not put the grid in a solid position to withstand new energy challenges. Power outages are becoming more frequent, and local and state governments are struggling to meet the demand. A PPS helps protect against energy uncertainty.

Off-Grid Living

More and more people are choosing to spend longer periods off-grid. It might involve extended vacations in remote locations, an RV lifestyle, or just opting to deliver your energy needs in a greener, more sustainable way.

No matter the reason, off-grid living presents its challenges, particularly when it comes to energy. But the portable PPS solutions reviewed here let you take power on the go. 

Conclusion

Anyone who uses a CPAP machine or has a family member who relies on one will understand its crucial importance in the home.

Peaceful and undisturbed sleep is essential for good health and daily function. The reverse — disrupted sleep and difficulty breathing — can make every day impossible.

CPAP machines are essential medical devices for many people, and a portable power station will always ensure you can plug in and drop off to sleep. EcoFlow provides a range of portable power stations to suit every need and location. Shop today to find the right PPS for you and keep your CPAP machine running all night — no matter what.
