The Jackery Explorer 1000 v2 is a strong choice if you need a portable power supply for a CPAP machine, especially for camping or emergency use. It offers a large 1,070Wh battery capacity, which should comfortably power most CPAP machines overnight. The 1500W AC output and pure sine wave AC ports ensure compatibility with sensitive medical devices like CPAPs. It’s fairly portable, weighing about 26 pounds and featuring a foldable handle, though it’s not the lightest option if you plan to carry it often.

One standout feature is its fast recharge time — it can fully charge in just one hour when using the emergency charging mode through the Jackery app, though the default is 1.7 hours to protect battery health. The battery uses durable LiFePO4 technology, meaning it retains most of its capacity even after thousands of charges, potentially lasting over 10 years. Additional features include multiple USB ports, a car DC port, and LED lights, allowing you to charge other devices simultaneously and use it in various settings.

Activating the fastest charging requires using the app each time, which might be inconvenient if you want a simpler experience.

The Jackery Explorer 2000 v2 is a powerful portable battery with a large 2042Wh capacity, which means it can run devices like CPAP machines for hours, making it a strong choice for those needing backup power during outages or camping. It supports up to 2200 watts output, so it can handle CPAP machines easily and even other devices at the same time. The unit is relatively light for its size at about 40 pounds, which is still portable but might be a bit heavy if you plan to carry it long distances.

Charging is very quick compared to similar products—it can reach 80% charge in just over an hour using AC power, and solar charging is possible though it requires separate panels. This makes it flexible if you want to recharge off-grid. It also features quiet operation and a safe, long-lasting LiFePO4 battery that can last up to 10 years. One standout feature is its uninterruptible power supply function, which offers near-instant switching to keep your CPAP running without interruption during power cuts.

But if you’re looking for something ultra-lightweight just for CPAP use, there are smaller options available.

The Anker SOLIX C300 is a solid choice if you need portable power for a CPAP machine during camping, travel, or emergencies. Its 288Wh battery capacity offers a decent amount of power that should keep most CPAP devices running through a night, depending on your machine’s consumption. The 300W continuous power output and 600W surge allow it to handle CPAP machines that require a bit more power to start.

The multiple ports let you charge other devices alongside your CPAP, which is a nice bonus.

This model is compatible only with specific Anker solar panels, so if you plan to rely heavily on solar recharging, you’ll need to buy those separately. The unit is fairly portable, being about 15% smaller than similar products, but it still weighs enough that it’s better suited for travel by car or RV rather than carrying long distances on foot. The quiet operation (about 25dB) is a big plus for ensuring your rest isn’t disturbed. Built with a long-lasting LiFePO4 battery, it promises durability and safety over time.

If you want a reliable, versatile portable power supply that can comfortably support a CPAP machine with some extra power for other devices, the Anker SOLIX C300 is a dependable option, especially when paired with the recommended solar panels. Just keep in mind the size and compatibility specifics when planning your setup.

Buying Guide for the Best Portable Power Supply For Cpap Machine

Choosing the right portable power supply for your CPAP machine is crucial to ensure you have a reliable source of power when you're on the go, whether you're camping, traveling, or experiencing a power outage. The right power supply will keep your CPAP machine running smoothly, ensuring you get the restful sleep you need. Here are some key specifications to consider when selecting a portable power supply for your CPAP machine.
Battery CapacityBattery capacity is measured in milliampere-hours (mAh) or watt-hours (Wh) and indicates how much energy the battery can store. This spec is important because it determines how long the power supply can run your CPAP machine before needing a recharge. Higher capacity batteries (e.g., 20,000 mAh or more) can provide power for longer periods, which is ideal for extended trips or power outages. If you only need a power supply for short trips or occasional use, a lower capacity battery may suffice. Consider your typical usage patterns and choose a battery capacity that aligns with your needs.
CompatibilityCompatibility refers to whether the portable power supply can work with your specific CPAP machine model. This is crucial because not all power supplies are compatible with all CPAP machines. Check the voltage and amperage requirements of your CPAP machine and ensure the power supply can meet these specifications. Some power supplies come with multiple adapters or are designed to work with a range of CPAP models, making them more versatile. Always verify compatibility before purchasing to avoid any issues.
PortabilityPortability is about the size, weight, and ease of carrying the power supply. This spec is important if you plan to travel frequently or need to carry the power supply with you. Smaller, lighter power supplies are easier to transport but may have lower battery capacities. Larger power supplies may offer more power but can be cumbersome to carry. Consider how and where you will be using the power supply and choose one that balances portability with your power needs.
Recharge TimeRecharge time is the amount of time it takes to fully recharge the power supply. This is important because a shorter recharge time means less downtime between uses. Recharge times can vary significantly between models, ranging from a few hours to over a day. If you need to use your CPAP machine frequently or have limited access to power sources, a power supply with a shorter recharge time will be more convenient. Evaluate your typical usage and choose a power supply with a recharge time that fits your schedule.
Additional FeaturesAdditional features can include things like built-in inverters, USB ports, solar charging capabilities, and LED indicators. These features can enhance the functionality and convenience of the power supply. For example, a built-in inverter allows you to use the power supply with other electronic devices, while USB ports can charge your phone or other gadgets. Solar charging capabilities can be useful for extended outdoor trips. Consider which additional features are important to you and choose a power supply that offers them.
