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 2024 to ensure a restful and healthy night’s sleep.
