5 Best Portable Power Stations for CPAP

For many years sleep apnea disorders had been a mystery for the medical science, and despite the fact sleep apnea is a common affection in patients of all ages, it wasn’t until 1980 that Australian physician Colin Sullivan, an inventive pioneer of sleep medicine first tested the revolutionary idea of applying positive pressure through the nasal airway to alleviate obstructed passageways as an experimental treatment to help patients with chronic sleep apnea problems. This is how CPAP therapy started.

Nowadays CPAP machines can be easily purchased to heal patients that are chronic sufferers of sleep apnea. CPAP medical devices are electronic units that generate a continuous flow of pressurized air that travels through into a flexible tube that delivers purified air into a mask that you put around your nose and mouth.

Operating a CPAP machine might require extra powering help if electricity from the power grid is not available, and this is when portable generators come in handy, to help your treatment not to be interrupted. If you or a member of your family are a CPAP user it is of critical importance you know the alternate power options you can acquire for your medical device if you live in an area prone to prolonged outages or if you are planning to take a road trip and you don’t want you or your loved one to sacrifice the relief hours that a CPAP machine offers.

In this article, we have put together a buying guide for you to find the best power stations that you can buy as a portable power supply for your CPAP machine.  

Let’s get started!

Portable Power Station Buying Guide

What is the Best Portable Power Station for CPAP?

Nevertheless, always keep in mind that any electronic device (your CPAP and your generator altogether) can generate ELF radiation (Extremely low-frequency radiation) therefore make sure that both units always work at a considerable distance of 20 centimeters away from you and the person you might share your sleeping space with.

Recommended brands for small generators that supply power efficiently to CPAP machines: Jackery, Goal Zero, Rockpals, Anker Powerhouse, Golabs.

How Do I Choose the Right Generator for My CPAP?

Although most small power stations might share characteristics in common, there are important differences among them that will be key for you to choose the right one that suits your needs. (Times to recharge, size, outlets, price, safety measures, and wattage). Portable compact power stations prices are usually affordable, you can get a good portable unit for as low as $170, $300 dollars on Amazon, however, the more features /wattage production a mini station might present, the higher the price of it will be.

FAQs

How long does a small generator last?

Unfortunately, due to the size of a small generator, they will likely die when their batteries do or their life cycles have ended. Generally, solar mini stations can last for over 6 years if well taken care of.

Can I take my generator on a flight?

Whereas fuel-powered generators are completely banned from all airlines, solar generators that don’t exceed 100Watt hours can be taken as part of carry-on luggage on an aircraft, however, the regulations for battery-operated devices on commercial flights are strict. We recommend you read the politics of carry-on and checked-in luggage of the airline you’re planning to choose for your trip in advance if you are up to take your small generator and/or your CPAP machine with you.

What is Pure Sine Wave in AC outlets?

Pure Sine Wave is part of the inverter technology in many portable generators that allows the AC universal outlets in them to run appliances smoothly, without voltage overloads, just as if those were powered from the house’s main power grid.

Can I take my generator and my CPAP on a road trip?

Double yes. Road trips always imply shortages of energy when powering gadgets such as smartphones, mini-fridges, cameras, etc. on the go. Taking your CPAP machine alongside a small power station will give you peace of mind that no matter where you are when the night falls, you will have safe power to breathe properly at night. 

Should I buy a power station for my CPAP machine?

It is a great idea to have an alternate power source for your CPAP machine in case of blackouts in your area or if you plan to move around and the worry of not being able to charge your CPAP machine everywhere you go is at the forefront of your mind. Have pleasure traveling and doing business or enjoying a good camping weekend if you know you can pack your CPAP alongside a battery partner that will make your life and your trips easier.
