What Is A Solar Generator For CPAP And Who Is This For


CPAP machines are commonly used by people that have sleeping issues such as sleep apnea and the like. As sleep apnea restricts the user’s airflow, the CPAP machine prevents this from happening by supplying a steady supply of pressurized oxygen.

Setting up the CPAP machine is no problem if you have a stable source of power. However, this is not always the case when it comes to camping. Some resources, electricity, especially, can become quite scarce depending on the camping location.

While some campsites may offer electricity hook-ups, these tend to be costly. Plus, there is no assurance that there wouldn’t be any power surges or failures. One could connect the machine to the car battery; however, there is a danger of overusing it. As such, the only remedy is using a portable power supply for CPAP machines.

Also known as solar generators, these portable power supplies are power banks you can use to charge up your CPAP machine. Most versions have solar panels, while some also come with a wall outlet to power up multiple devices.

Remember to match the generator with the machine’s specifications. Most CPAP devices require about 30-60 watts of power and at least a 175-watt inverter. However, it’s highly recommended that you check your CPAP unit before purchasing a generator.

How Does It Work

CPAP portable power supplies are a type of solar technology as that relies on it to generate electricity. They come with foldable solar panels containing photovoltaic cells that are responsible for collecting and converting sunlight into electric currents.

These cells are wired into circuits and series to form a module. The specifications for each module differ in terms of the voltage and wattage they produce, but all of them produce DC electricity.

Like most devices, the CPAP machine also cannot use DC power directly. Hence, the generator also comes with an inverter to convert DC electricity into AC electricity.

Once it’s converted, the AC power then supplies electricity to ger your device running. The excess electricity is then stored in a battery for later and emergency use.

The top-tier time to charge the generator is during sunny days. You can still charge it during cloudy or overcast days, but it would take a longer time.

Most CPAP machines typically consume about 40-150 watts per hour or more, depending on the device’s features and specifications. Of course, the more hours you use the machine, the larger amount of electricity it is going to consume. Make sure to choose a solar generator that can match and keep up with your CPAP machine’s needs.

Frequently Asked Questions


How long can a solar generator power a CPAP machine?

How long you can run a CPAP machine on a generator depends on the generator’s electrical output and the CPAP’s energy demand. A rough formula for operation time is the generator’s Wh x 0.85 /CPAP’s wattage.

As a rule, the generator’s power output must be sufficient to supply the CPAP’s electrical requirements.

For example, a solar powered CPAP machine for infants must deliver positive air pressure for 12 to 16 hours nonstop. On the other hand, toddlers might only require 11 to 14 hours, while adults need at least seven hours.

The good news is that many solar-powered CPAP generators have extended runtimes. For instance, the 1100Wh Inergy Apex can run a 30-watt CPAP machine for at least 36 hours, while the 1300Wh EcoFlow Delta 1300 will operate the same medical equipment for more than 43 hours.

How many watts does a CPAP machine use?

A continuous positive airway pressure (CPAP) machine operating on AC electricity can run on as little as 80 watts or as much as 120 watts. The demand is slightly lower for DC devices, at 60 to 100 watts.

It is crucial to recognize that many pieces of modern equipment have nominal and peak power requirements. Nominal power refers to the machine’s normal-load electrical consumption, while peak power reflects its electrical requirements during heavy load or extended operation.

Hence, a CPAP might have an 80-watt nominal rating but can jump to 135 watts at certain times.

As a rule, the CPAP solar generator should accommodate the machine’s peak power requirement (i.e., 135 watts).

What size generator do I need to run a CPAP machine?

A portable generator for the CPAP machine should deliver sufficient electricity to run the medical equipment.

Determine how long you’ll need to run the CPAP, then calculate its power consumption by multiplying its wattage and run time.

The result will be the minimum size of the solar generator kit for camping, though I recommend upsizing it, especially if you also use the generator for other appliances.

What is the most trusted solar generator for CPAP brands?

There are different versions and variants of solar generators you can choose from in the market. While variety is welcomed, having this amount of choices can also make it challenging to select a model that works for you.

Regardless, doing your research is essential. You can do this by reading product reviews online or going to your local store and checking the product out for yourself. Many users also tend to look at brands and manufacturers. Recommended manufacturers include:

  • FF Flashfish Store
  • SereneLife Store
  • Jackery Store
  • ROCKPALS Store
  • BALDR Store

These companies are known to provide high-quality and efficient solar generators for just a fraction of a price.

How to use?

A solar generator collects and converts solar energy into electricity that can be used to operate your CPAP machine. To do this, it typically has the following features: solar panel, battery pack, inverter, and charge controller.

Using your solar generator is easy since it only has minimal parts and doesn’t require the user to operate it. You just need to set the solar panels up in a sunny area and connect it to the battery pack.

When this happens, the solar panel’s cells collect solar energy and convert it into DC energy. A good portion of this energy is stored in the battery pack for later use.

The other half, however, travels to the solar generator’s inverter, where they will be converted into AC energy. This is because most appliances cannot run on DC energy.

Once converted, AC energy then flows into the generator’s charge controller. This controller controls the current flow leaving the generator.


Having your solar generator is a great and useful investment, especially when you tend to travel and camp out a lot. With this, you have the convenience of having a constant and stable power source to charge and recharge your CPAP machine. As such, you can have a comfortable night of sleep, even when engaging in different outdoor activities.

Due to their popularity, there are different solar generators you can choose from. Even so, selecting the best one for your CPAP machine can be challenging. Hopefully, this buying guide on the best solar generator for CPAP has provided you with enough information and data to help you make your choice. Safe travels!
