10 Best Portable Power Supply For Cpap Machine 2026 in the United States

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. If you want a versatile, reliable, and relatively fast-charging power station with long-term durability, this product fits well. However, if you prioritize ultra-lightweight design or plug-and-play simplicity, you might want to consider other models.

The EF ECOFLOW DELTA 3 Classic is a powerful portable power station with a large 1024Wh LiFePO4 battery, offering enough capacity to run a CPAP machine overnight with ease. Its 1800W output supports even heavier appliances, and the built-in X-Boost technology adds flexibility for different devices. For CPAP users, the most important feature is its <10ms UPS capability, which ensures an instant switch to battery power during outages, preventing any interruption in therapy.

The unit charges very quickly, reaching 80% in just 45 minutes, and can be recharged via solar panels in about 2.5 hours, making it suitable for both home backup and outdoor use. While it weighs about 27 pounds and measures roughly 8 by 11 by 16 inches, it remains portable enough for camping or RV trips, though it’s not as lightweight as smaller CPAP-specific batteries. The smart app control adds convenience by letting you monitor and manage power usage easily.

A possible downside for some could be the price and size compared to simpler CPAP-only batteries, but its versatility and fast recharge make it a solid choice for users who want a reliable, long-lasting power source for CPAP and other devices.

The Jackery Explorer 300 is a compact and lightweight portable power station with a 293Wh lithium-ion battery, making it suitable for camping, travel, and emergency backup. Its 300W continuous power output and pure sine wave inverter provide clean, stable electricity, which is important for sensitive devices like CPAP machines. The unit offers multiple charging options, including two AC outlets and several USB ports, allowing you to power your CPAP and other devices simultaneously.

Weighing just over 7 pounds and coming with a carrying bag, it’s easy to take along on outdoor trips or move around the house during outages. The recharge time is relatively fast, especially if you use Jackery’s solar panels (sold separately), which is handy if you’re off-grid for long periods. However, the 293Wh capacity means it may need recharging every night if you use it for a CPAP machine overnight, depending on your machine’s power needs.

This model represents a reliable, portable power supply with clean output. If you require longer runtimes without recharging, you might need a higher-capacity model. Its versatility and ease of use make it a good fit for CPAP users who also want a power source that can handle other small electronics during outdoor activities or emergencies.
