Whether you’re a first-time boondocker or a seasoned off-grid camper, these insights will help you make the most of your trip while prioritizing your health and well-being.

Invest in a Reliable Portable Power Source

Without access to shore power, having a dependable power source is essential for running your CPAP machine through the night. Portable power stations, such as a Jackery Explorer, EcoFlow Delta, Bluetti, Anker Solix or Goal Zero Yeti, provide rechargeable battery banks with multiple outlet options, including AC, DC, and USB. These power stations are versatile and can also power other devices, such as phones, lights, and laptops.

When choosing a portable power station, look at its watt-hour (Wh) rating. Your CPAP machine’s wattage requirements determine how long the station will last. For example, if your CPAP machine uses 40 watts per hour and you plan to sleep 8 hours, you’ll need a power station that provides at least 320 watt-hours, plus some extra capacity to account for energy fluctuations. Solar-powered generators are a fantastic option for boondocking, as they allow you to recharge the power station during the day using portable solar panels. This ensures you won’t run out of power, even if you’re camping off-grid for several days.

First, if you are looking for a power source to allow you to go off grid for a couple weeks at a time without recharging, this is the Jackery you probably want, but it is on the spendy side.  And you can also use it to power other things in your RV as well, once you get comfortable with usage.

Use a DC Power Adapter for Your CPAP

Most CPAP machines come with an AC power adapter (a standard wall plug), but using a DC power adapter is more efficient when boondocking. A DC adapter plugs directly into a 12-volt outlet in your vehicle, RV, or power station, avoiding the need to convert power through an inverter, which can waste energy. DC adapters provide a direct current that requires less energy and puts less strain on your power system, extending the life of your battery.

DC power cords for CPAP machines are often sold separately, so check your machine’s specifications to ensure you purchase the correct one. Many popular CPAP brands, such as ResMed and Philips, offer their own DC adapters designed to work seamlessly with their machines. Additionally, a DC adapter is a more versatile option since you can use it to charge directly from your vehicle’s cigarette lighter if needed, giving you more flexibility when boondocking.

Check where each DC power supply socket is pulling from if you are using an RV.  Generally the ones in the cab area draw off the engine’s battery while ones in the living part of the RV pull from the RV batteries.  You want to make sure you don’t draw from the engine batteries repeatedly and slowly drain the engine’s battery.  The power draw on your CPAP will determine how many days worth of battery power you can use without running the engine to recharge.

Here is the standard DreamStation DC cord:

Turn Off the Heated Humidifier

The heated humidifier on your CPAP machine can be one of the biggest power drains, often using more energy than the machine itself. When boondocking, turning off the humidifier can drastically extend the battery life of your power source. The humidifier heats water to add moisture to the air, but this function can easily double your CPAP machine’s wattage requirements.

If you need some moisture to avoid dry airways, you can use the humidifier chamber in “passover mode.” This means filling the chamber with water but leaving the heater off. The airflow passes over the water, picking up some moisture naturally without using additional power. You can also use alternative methods, such as saline nasal sprays or a room humidifier powered by a low-wattage battery pack, to keep your airways comfortable. Adjusting your settings may take a few nights to get used to, but the power savings make it worthwhile, especially during extended boondocking trips.

Use a Portable Battery Pack as a Backup

A dedicated CPAP battery pack provides a reliable backup power source, ensuring you can still run your machine even if your main power station runs out of charge. Many CPAP brands offer proprietary battery packs designed to work specifically with their machines. For example, the ResMed Power Station II and the Philips Respironics Battery Kitare lightweight, portable, and designed to provide a full night’s power or more.

Having a portable battery pack also provides flexibility when camping off-grid. You can charge it separately during the day using your vehicle, solar panels, or even a small generator. Many of these batteries are compact enough to carry with you for overnight backpacking trips as well. Additionally, some portable power banks come with USB-C or DC ports that can serve as a secondary backup in case of an emergency. By having a backup battery, you can sleep soundly knowing you have a contingency plan in place.

Choose a CPAP-Friendly Solar Panel Setup

For long boondocking trips, having a solar panel system to recharge your power station or battery pack can be a game-changer. Solar panel kits, like the Renogy Foldable Solar Suitcase or the Jackery SolarSaga, are designed to be portable and easy to set up at your campsite. They collect energy from the sun and feed it directly into your power station, allowing you to recharge during the day and run your CPAP at night.

When selecting a solar panel setup, consider the wattage output and your power station’s input capacity. For example, if your power station can handle a 100-watt solar input, choosing a 100-watt or higher panel will recharge it faster. Even partial recharges during cloudy weather can extend your off-grid time by boosting your battery. Additionally, solar panels give you an eco-friendly way to keep your CPAP running, making them an essential investment for frequent boondockers.

Many boondockers choose high-capacity solar panel setups, such as the Jackery Solar Generator 2000 with 200W SolarSaga panels, when budget isn’t a limiting factor. This setup provides a reliable and powerful solution for recharging large-capacity power stations, making it ideal for longer off-grid trips where you need to power your CPAP machine along with other devices, such as lights, fans, and cooking appliances.

While these premium bundles can be pricey, they offer the convenience of plug-and-play functionality and often include high-quality components that last for years. The panels’ high wattage ensures faster recharges, even when the sunlight is limited, giving you peace of mind during extended stays in remote locations.

Reduce Altitude Pressure Adjustments

If you’re camping at high elevations, your CPAP machine may automatically increase pressure to compensate for thinner air. While this adjustment is important for maintaining effective therapy, it can also use more power. If your CPAP has a manual pressure setting, you may be able to lower the pressure slightly to conserve battery life, especially if the change doesn’t impact your comfort.

Before making any adjustments, consult with your doctor or sleep specialist to ensure the changes won’t compromise your therapy. Newer CPAP models, such as the ResMed AirSense 10, have adaptive pressure algorithms that balance effective therapy with efficient power use, making them a smart investment for high-altitude camping.

Not sure of altitude?  There are a few devices that can tell you your current altitude, although most are part of a multifunction device, such as this one which also does temperature, Co2 levels, and humidity.  You will want to discuss with your doctor before making any major adjustments to pressure that the machine does not do automatically to be sure.
