  • Built-in LED flashlight.


  • Single AC outlet.

Our Review

Best Features


This solar generator features a sturdy build with a compact design. A built-in handle makes it easy to carry around and transport. It is compatible with various devices (phones, laptops, etc.) and CPAP machines. 

Another handy feature is the LED flashlight, which is quite helpful at night for visibility. It also has multiple safety features to prevent overheating, overcharging, discharging, and short-circuiting.

Easy Recharging

Recharging this solar generator is a breeze. You can recharge it via a wall outlet, solar panel, or carport.

It is better to pair it with a compatible solar panel to achieve quick and reliable charging from 0% to 80% in about 6 hours. The LED indicators help you monitor the power levels to mark ease of use.

Charging Ports

Another good thing about this solar generator is that aside from running your CPAP machine for around 4 hours, it can power other devices simultaneously.

There are three DC ports, three USB ports, and one AC port for versatile usage. 


SereneLife unit has only one AC outlet, which is a bit disappointing. Also, it’s not the most powerful unit, Wh-wise, out there. It won’t keep your CPAP machine running through the night. But at least, it is quite affordable.

Buying Guide For CPAP Solar Generators

best solar generator for cpap

Now let's talk about solar generators and what you should keep in mind when trying to pick the best one for running a CPAP machine off the grid.

This information will help you make an informed buying decision.

What is a Solar Generator?

best solar generator for cpap

A solar generator is made up of three components:

  • Solar panels w/ charge controller
  • Battery Storage
  • Inverter

Solar panels are positioned towards the sunlight to collect solar energy. The panel converts this energy into direct current electricity. This energy is stored in the inbuilt solar battery of the generator via the solar charge controller, which prevents damage to the battery.

The inverter, which is a part of a solar generator, converts the DC into alternating current (AC) to run 115V and/or 230V appliances.

Features To Consider

best solar generator for cpap

Power Rating and Battery Capacity

Most CPAP machines consume 30-60 watts of power and require 150 Watt inverters at a minimum. For an 8-hour night’s sleep, assuming no other devices are connected and that your generator will cut off at 50% discharge to protect your batteries, your solar generator should be rated at 500Wh at a minimum. 

Ports And Outlets

Different people have different lifestyles and charging requirements. For example, campers will want to carry one unit to power not just their CPAP but also their electronics, lights, and 12V cooler.  In this situation, you’ll do better buying a 1,000Wh or larger solar generator with lots of port options. 


Solar generators can be large and heavy, so you may like to look for the one that has a compact size and less weight, such as the Jackery Solar Generator 240.

Frequently Asked Questions

What’s the difference between CPAP, APAP, and BiPAP machines?

There are three main types of sleep apnea machines: CPAP, APAP, and BiPAP. CPAP is the most common type and stands for continuous positive airway pressure. This machine pumps a constant stream of air into your airways to keep them open. 

APAP, or automatic positive airway pressure, is a newer type of machine that adjusts the pressure depending on how you’re breathing. If the pressure is too high, it will lower it. And if the pressure is too low, it will raise it. 

BiPAP, or bilevel positive airway pressure, delivers pressure for inhaling and exhaling. Whereas CPAP delivers only one pressure. 

Depending on the solar generator you opt for, you can easily power a CPAP machine.

How many watts does a CPAP machine use?

A typical CPAP machine uses 30-60 watts.

How long can a solar generator power a CPAP machine?

Typically, a CPAP machine uses 30-60 watts and requires a solar generator of at least 500Wh if you want the CPAP machine to give you 8 hours of sleep. If you will be running other devices along with the CPAP machine, it is recommended to opt for a 1000Wh model.

Will a 200, 300, And 400 watt inverter run a CPAP machine?

Yes, most CPAP machines can be powered by 400, 300, or even 200 watt inverters.

How do I use my CPAP machine for camping?

The most important thing is to have a power source when using a CPAP machine for camping. A reliable solar generator can run a CPAP machine for at least one night per day of charging.

Final Verdict: What Is The Best Solar Generator For CPAP Backup?

In our opinion, the BLUETTI Portable Power Station AC200MAX is a great all-use solar generator with enough power to handle your CPAP for several nights or a bunch of other devices.

This is the unit for you if you’re looking for a solar generator for running a variety of appliances along with your CPAP machine.

But of course, feel free to re-read our list to find the best solar generator to help backup CPAP devices when you’re out and about.
