If you use a CPAP machine, you know the specific kind of anxiety that comes with camping. While everyone else is worried about mosquitoes or rain, you're doing mental math about voltage, amp hours, and pressure settings. I've been there. The fear of being miles from an outlet and realizing you can't sleep safely is real. But here's the good news: modern battery technology has caught up.
Gone are the days of hauling heavy deep-cycle marine batteries into the woods. Today's portable power stations are lithium-based, silent, and surprisingly lightweight. However, not all of them can handle the specific demands of a heated humidifier or a high-pressure setting all night long. Choosing the wrong one means waking up at 3 AM to a silent machine and a suffocating mask.
In this guide, we're cutting through the marketing fluff. We've analyzed 7 top contenders to see which ones actually have the juice to keep your CPAP running from dusk 'til dawn, so you can enjoy the great outdoors without sacrificing your health.

1. Jackery Portable Power Station Explorer 300
There's a reason you see orange and black boxes at every campsite—Jackery has built a reputation for simply working. The Explorer 300 is what I consider the "Goldilocks" size for weekend warriors using CPAP. It's not a back-breaking generator, but it's not a toy either. It fits easily on a tent floor table and feels incredibly rugged.
Quick Specs:
- Capacity: 293Wh Lithium-ion
- AC Output: 300W (500W Surge)
- Recharge Time: 2.5 Hours (Wall + USB-C)
- Weight: 7.1 lbs
Why We Like It
- Perfect Capacity Sweet Spot: At 293Wh, this can typically run a CPAP for 2 nights (if you turn the humidifier OFF), which is exactly what most weekend campers need.
- Pure Sine Wave: The 300W AC outlet provides clean power, meaning it won't damage sensitive medical motors or cause them to whine/hum.
- Fast Dual Charging: You can plug it into the wall AND use the USB-C port simultaneously to charge it in just 2.5 hours—huge if you're juicing up quickly before leaving.
The Drawbacks
- Older Battery Tech: It uses standard Lithium-ion, not LiFePO4, so it has a shorter overall lifespan (cycles) compared to newer models like the Anker SOLIX.
- Fan Noise: The cooling fan can kick on during charging or heavy loads, which might be annoying in a silent tent.
The Bottom Line: If you want the safe bet that has been battle-tested by thousands of campers, this is it. It's reliable, simple, and hits the capacity sweet spot.
Best For: Weekend campers who want a trusted brand and don't need to power a heater or fridge.
2. Jackery Explorer 1000 v2 Portable Power Station
If you're planning an extended off-grid trip or you simply refuse to give up your heated humidifier, the Explorer 300 won't cut it. Enter the Explorer 1000 v2. This is a serious power plant. Jackery managed to shrink the size by 20% compared to the old model, making it surprisingly manageable for such a high-capacity beast.
Quick Specs:
- Capacity: 1070Wh LiFePO4
- AC Output: 1500W (3000W Surge)
- Battery Life: 4000+ Cycles
- Fast Charge: 1 Hour (Emergency Mode)
Why We Like It
- Massive Runtime: With 1070Wh, you could easily get 4-7 nights of CPAP use (without humidifier), or 2-3 nights with full comfort settings enabled.
- Long-Lasting Battery: The switch to LiFePO4 battery chemistry is a game changer, offering 4000+ charge cycles compared to the industry standard of 500-800.
- Lightning Fast Charge: The ability to fully recharge in just 1 hour means you can easily top it off at a gas station or ranger station while grabbing a coffee.
The Drawbacks
- Heavy Investment: It's overkill for a single night of camping and costs significantly more than smaller units.
- Physical Weight: While "compact" for its class, it's still a lug. You aren't hiking with this; it's strictly for car camping.
The Bottom Line: The ultimate peace-of-mind machine. If you have anxiety about running out of power, this kills that fear dead.
Best For: Overlanders, long-term campers, and CPAP users who need their heated humidifier.
3. MARBERO 88Wh Portable Power Station
Let's be real—sometimes you just need the cheapest possible option to get you through a single night or a nap. The MARBERO 88Wh is tiny. It looks more like a chunky oversized power bank than a generator. It's cute, ultra-portable, and fits in a backpack, but you need to manage your expectations regarding power.
Quick Specs:
- Capacity: 88Wh (24000mAh)
- AC Output: 80W (120W Peak)
- Weight: 2.4 lbs
- Extras: Built-in LED Flashlight
Why We Like It
- Incredibly Light: At 2.4 lbs, you can actually hike with this. It adds barely any weight to your pack.
- Versatile Charging: Despite its size, it still supports solar input and car charging, giving you flexibility on the go.
- Price Point: It is significantly cheaper than the major brands, making it an easy entry point.
The Drawbacks
- Critically Low Capacity: 88Wh is very risky for a full night of CPAP. Even without a humidifier, a standard machine might drain this in 4-5 hours depending on pressure.
- Low AC Limit: The 80W max output cuts it close for some older CPAP machines during startup (surge).
The Bottom Line: This is an emergency backup, not a primary camping power source. It's great for charging phones or maybe a 2-hour nap, but don't rely on it for 8 hours of sleep.
Best For: Hikers needing a phone charger who might need CPAP for a short nap.
4. Anker SOLIX C300 Portable Power Station (AC)
Anker has been dominating the charging game, and the SOLIX C300 is their answer to the portable power station market. It feels much more "modern" than the Jackery 300. The design is vertical, sleek, and it features a pop-up handle that makes it feel like carrying a lunchbox. It's packed with tech that geeks will love.
Quick Specs:
- Capacity: 288Wh LiFePO4
- AC Output: 300W (600W SurgePad)
- USB-C: 140W Bi-directional
- Build: Integrated Light Bar
Why We Like It
- Long-Life Battery: Unlike the older Jackery 300, this uses LiFePO4 cells, meaning it will last for years of daily use without degrading.
- App Control: You can check your remaining battery percentage via Bluetooth on your phone—no need to unzip the tent and crawl over to the unit to check the screen.
- Superior USB-C: The 140W USB-C ports are powerful enough to charge a laptop at full speed while running your CPAP.
The Drawbacks
- Vertical Design Instability: Because it's tall and thin, it can be slightly easier to knock over in a dark tent compared to the wider, flatter Jackery.
- App Connectivity: Bluetooth range can be finicky if you wander too far from the campsite.
The Bottom Line: This is currently the best "smart" portable station for CPAP. It matches the Jackery in power but beats it in features and battery longevity.
Best For: Tech-savvy campers who want app monitoring and modern USB-C speeds.
5. HOWEASY Portable Power Station 88Wh
The HOWEASY 88Wh is another contender in the ultra-lightweight category. It sports a high-visibility yellow design that makes it easy to find in a messy trunk. Like the Marbero, this is designed for extreme portability rather than endurance, but it offers a slightly higher peak output for its size.
Quick Specs:
- Capacity: 88Wh Lithium
- AC Output: 120W (240W Peak)
- Ports: 8 Total Outputs
- Weight: 2.3 lbs
Why We Like It
- Port Density: For such a tiny brick, having 8 output ports is impressive, allowing you to charge multiple USB devices alongside a small AC appliance.
- Higher Peak Power: The 120W AC rating (vs 80W on the Marbero) gives it a bit more headroom for starting up devices without tripping the overload protection.
- Rugged Shell: The casing feels durable and ready to take a few bumps in a camping bin.
The Drawbacks
- Capacity Anxiety: Again, 88Wh is simply too small for a safe night's sleep on CPAP. It is strictly for backup or very low-pressure settings.
- Slow Charging: It takes quite a while to recharge via the included wall adapter compared to the fast-charging Anker or Jackery units.
The Bottom Line: A decent budget gadget for charging phones and lights, but for CPAP, it's a risky gamble unless you have a DC converter and low pressure needs.
Best For: Backup emergency power for lights and phones.
6. Bailibatt 300W Portable Power Station
You might not have heard of Bailibatt, but they offer a compelling value proposition. This unit sits right in the competitive 300W range but often comes in at a lower price point than the big names. It's a no-frills, boxy unit that focuses on getting the job done without fancy apps or designs.
Quick Specs:
- Capacity: 257Wh
- AC Output: 300W (600W Peak)
- Waveform: Pure Sine Wave
- Management: Smart BMS System
Why We Like It
- Value for Money: You get near-Jackery performance (300W output) for a fraction of the cost.
- Pure Sine Wave: Crucial for CPAP users—this ensures the power is clean and safe for your machine's motor.
- Decent Capacity: At 257Wh, it's just shy of the Jackery/Anker capacities but should still comfortably provide one full night of therapy (without humidity).
The Drawbacks
- Generic Build: The plastic casing and buttons don't feel as premium or weather-sealed as the top-tier brands.
- Slightly Lower Capacity: That missing ~30-40Wh compared to the Anker/Jackery might be the difference between waking up fully charged or with a dead battery.
The Bottom Line: A solid budget alternative for the one-night camper who wants to save cash but needs more than the 88Wh toys.
Best For: Budget-conscious campers doing single-night trips.
7. Anker SOLIX C300 DC Portable Power Station
Warning: Read this carefully. This is the "DC" version of the Anker SOLIX C300. It looks almost identical to the AC version, but it lacks one major feature: a wall outlet. Why would you want this? Because by removing the AC inverter, it becomes smaller, lighter, and more efficient for DC-native devices.
Quick Specs:
- Capacity: 288Wh LiFePO4
- AC Output: NONE (DC Only)
- Ports: USB-C (140W), USB-A, Car Socket
- Carrying: Shoulder Strap Included
Why We Like It
- Maximum Efficiency: If you have the 12V DC adapter for your CPAP machine (which you should!), this unit is incredibly efficient because it doesn't waste energy converting DC to AC.
- Shoulder Strap: It comes with a strap and is designed to be carried like a messenger bag, making it the most portable "serious" battery on this list.
- Pop-Up Lantern: The built-in light is fantastic for setting up your tent in the dark.
The Drawbacks
- NO AC OUTLET: I can't stress this enough. If you only have your standard wall plug for your CPAP, this unit is useless to you. You MUST own the specific DC cigarette lighter adapter for your machine.
- Niche Use: You can't use it to plug in a standard laptop charger or small fan unless they are USB-C.
The Bottom Line: If you are a pro camper with a 12V DC cord for your CPAP, this is arguably the best choice. It cuts the fat and gives you pure, efficient DC power.
Best For: Advanced users who own 12V DC adapters and want maximum portability.
Buyer's Guide: How to Choose a Power Station for CPAP
Buying a battery for a medical device is different than buying one to charge a phone. Here is what you need to know to avoid a sleepless night.
1. Capacity Math (The "Wh" Rule)
Battery capacity is measured in Watt-Hours (Wh). To guess how long your CPAP will run, you need to know its wattage draw. A standard CPAP at medium pressure draws about 30-60 watts.
Formula: Capacity (Wh) × 0.85 (Efficiency Loss) ÷ Device Wattage = Hours of Runtime.
For example, the Jackery 300 (293Wh) running a 40W CPAP:
293 × 0.85 ÷ 40 = ~6.2 hours.
PRO TIP: This math changes drastically if you use the heated humidifier. A humidifier can double or triple the power draw. Turn off the heater/humidifier to extend your runtime by 2-3x.
2. AC vs. DC Cables
Most power stations have a standard wall outlet (AC). However, plugging your CPAP's brick into the battery's AC outlet wastes energy because the battery has to convert its DC power to AC, and your brick converts it back to DC. This double conversion wastes 10-20% of the battery.
For the longest runtime, buy the specific 12V DC Converter Cord for your CPAP brand (ResMed, Philips, etc.) and plug it directly into the round "cigarette lighter" port on the power station.
3. LiFePO4 vs. Lithium-ion
You'll see terms like "LiFePO4" on newer units like the Anker SOLIX and Jackery 1000 v2. This stands for Lithium Iron Phosphate. These batteries last for 3000-4000 recharge cycles (about 10 years of daily use). Older standard Lithium-ion batteries (like the Jackery 300) last about 500 cycles. If you camp every weekend, get LiFePO4.
FAQ
Q: Will these power stations run my heated humidifier?
A: Yes, the larger ones (300Wh+) technically can, but it will drain the battery incredibly fast—often in less than 4 hours. We strongly recommend turning the heat/humidity off or to "passive" mode when camping.
Q: Can I take these on an airplane?
A: Generally, no. The FAA limit for spare lithium batteries is usually 100Wh, sometimes up to 160Wh with airline approval. The Marbero and Howeasy (88Wh) are safe for carry-on, but the Jackery 300 and Anker C300 are too big to fly with.
Q: Do I need a Pure Sine Wave inverter?
A: Yes. CPAP machines have sensitive motors. "Modified Sine Wave" inverters (often found in very cheap units) can cause the motor to overheat, hum loudly, or fail. All the major units on our list (Jackery, Anker) use Pure Sine Wave.
Q: How do I recharge these while camping?
A: You can recharge them via your car's 12V socket while driving (slow), or use portable solar panels (sold separately). Solar is the best option for multi-day trips.
Final Verdict
Choosing the right power station comes down to how long you plan to stay off the grid.
- For the classic weekend camper who wants reliability, grab the Jackery Explorer 300. It's the standard for a reason.
- For modern features and longevity, the Anker SOLIX C300 (AC) is the new king of the hill with its LiFePO4 battery.
- If you are doing serious overlanding or need humidity, do not skimp—invest in the Jackery Explorer 1000 v2.
Sleep well, and enjoy the stars!
