How to Choose Solar Generators for CPAP

Calculate Your CPAP Power Requirements

Start by checking your CPAP machine’s wattage, typically found on the power supply label. Most CPAP machines use 30-60 watts, but heated humidifiers can increase consumption to 90 watts or more.

Multiply your machine’s wattage by the hours you’ll use it to determine minimum capacity needed. For example, a 40W CPAP running 8 hours requires 320Wh minimum, but aim for 400-500Wh to account for efficiency losses.

Battery Capacity and Runtime

Solar generator capacity is measured in watt-hours (Wh). Divide the capacity by your CPAP’s wattage to estimate runtime—a 300Wh generator powering a 30W CPAP provides about 8.5 hours after accounting for 85% efficiency.

Consider whether you need single-night coverage or multi-day capability. Weekend campers can manage with 250-300Wh, while extended trips or emergency backup requires 500-1000Wh or more.

Battery Type and Longevity

LiFePO4 (lithium iron phosphate) batteries last 3000-4000 charge cycles and maintain capacity for 10+ years. Standard lithium-ion batteries typically offer 500-1000 cycles before significant degradation.

LiFePO4 costs more upfront but delivers better long-term value for frequent users. If you only camp occasionally, standard lithium-ion batteries provide adequate lifespan at lower cost.

Pure Sine Wave Output

CPAP machines require pure sine wave AC power to operate safely and quietly. Modified sine wave inverters can damage sensitive electronics or cause loud humming noises.

All generators in this roundup feature pure sine wave outlets, but always verify this specification before purchasing any portable power station for medical equipment.

Portability and Weight

Weight ranges from 4 pounds for compact units to 25+ pounds for high-capacity models. Consider how you’ll transport the generator—backpacking demands ultra-light options while car camping allows heavier units.

Check dimensions to ensure it fits your storage space. Foldable handles and compact designs make transportation easier, especially for frequent travelers.

Frequently Asked Questions

How long will a solar generator run my CPAP machine?

Runtime depends on generator capacity and CPAP wattage. A 300Wh generator typically runs a 30W CPAP for 8-9 hours, while 1000Wh provides 28+ hours of operation.

Can I use a solar generator with a CPAP humidifier?

Yes, but heated humidifiers significantly increase power consumption to 60-90W total. You’ll need a larger capacity generator or consider using the humidifier without heat to extend runtime.

Do I need to buy a solar panel separately?

Some generators include solar panels while others require separate purchase. Check the product listing carefully—the Jackery 300 and 600W models include panels, while others like the ALLWEI require buying them separately.

How do I know if my CPAP is compatible?

All CPAP machines work with pure sine wave AC outlets. Check your CPAP’s wattage on the power supply label and ensure the generator’s capacity and AC output exceed that requirement.

Can I charge the generator while using my CPAP?

Yes, most solar generators support pass-through charging, letting you run your CPAP while simultaneously recharging from AC, solar, or car outlets. This is especially useful during extended power outages.

Final Thoughts

The Jackery Solar Generator 1000 v2 offers the best overall performance with its massive capacity and 10-year lifespan, while the ALLWEI 300W provides excellent budget value for occasional users.

Choose based on your typical usage—weekend campers need 250-300Wh capacity, while frequent travelers or emergency backup requires 500-1000Wh with LiFePO4 batteries. Always calculate your CPAP’s actual power consumption including any humidifier usage.

Pure sine wave output and adequate capacity are non-negotiable for CPAP machines. Invest in quality now to ensure uninterrupted sleep therapy wherever your adventures take you.
