Solar Panels: Battery Backup and Power Sources for CPAP Machines

Planning ahead for your next outdoor adventure? Bring along your CPAP therapy because relying on your usual power supply is a thing of the past. 

Now, are you wondering how you can get out from under the stresses surrounding the lack of power?

Well, solar panel options like the BPS SunPower Solar Panel and the Somnetics Solar Charger for Transcend Batteries grant you the freedom to spend some time in the great outdoors camping, hiking, or simply going off-the-grid.

If you’re an avid camper or overnight hiker, then the flexibility of a travel CPAP machine paired with a solar panel will allow you to keep on adventuring with your CPAP therapy in tow. Talk about the perfect combination!

How Do Solar Panels Work?

You simply connect your solar panels to your battery to charge during the day. A foldable and compact solar panel draws energy from the sun, allowing you to charge your CPAP battery pack on-the-go. You simply open the buckles and release the panels. You will then place them in direct sunlight to transfer solar energy to your battery.

Cloudy day? The solar panels not only harvest the sun’s energy when in direct and full sunlight but also on cloud-covered days as well. Once you harvest the sun’s energy, you can be confident that your battery is ready for your night’s sleep.

Benefits of Solar Panels to Charge Your CPAP Battery

Using a solar panel to charge your CPAP battery will keep you sleeping soundly in nature. With the help of the sun, you can charge your CPAP batteries to power your travel CPAP machine in the great outdoors.

Solar panels are lightweight. The panels fold up easily, which allows you to fit them into your travel bag or backpack comfortably. They can fully charge a battery in 6 to 12 hours, depending on the battery you’re using. You just connect your battery to the solar panel, place it in direct sunlight, and your machine will be charged before it’s time for bed at night. The most convenient part? You can forget having to search for a campsite with electricity.

Most solar panels are made using green technology and are carbon-footprint friendly so you will be helping the environment in the process.
