I sleep with a CPAP machine every night, and I got tired of worrying about power outages killing my therapy. I needed a portable power station that could quietly run my CPAP all night long while keeping my phone topped up. After testing seven Anker SOLIX models side by side, I found clear winners for different needs and budgets.
Every station on this list uses LiFePO4 battery chemistry, which is safer and lasts way longer than older lithium-ion packs. I ranked them based on real-world run time for a CPAP (typically 30-60 watts), how many USB ports are available for phones, total weight for moving around the house, and how fast they recharge. These are the only models I’d actually trust for a full night’s sleep.

How I Selected These Products
I focused on models that could actually run a CPAP machine and charge a phone simultaneously without breaking a sweat. That meant looking closely at each unit’s continuous output watts, battery capacity in watt-hours, and the number of USB-A and USB-C ports available. A station that can’t handle both devices at once didn’t make the cut.
Value mattered just as much as raw specs. I considered how fast each power station recharges from a wall outlet, how heavy it is to carry from room to room, and whether the included accessories are actually useful. A great price means nothing if the station is too heavy to move or takes all day to refill.
I also combed through hundreds of real user reviews to see how these units hold up over months of use. Reliability is everything when your CPAP therapy depends on it, so I only included models with consistently strong feedback about noise levels, battery longevity, and charging performance. No station made this list if multiple owners reported early failures.
Best Overall
Anker SOLIX F2000 Portable Power Station
2400W Output | 2048Wh Capacity | LiFePO4 | GaNPrime | 4.4 Stars (958 Reviews)
- [Longest-Lasting 10-Year Lifespan] - With InfiniPower's long-lasting...
- [Rapid Recharge] - Thanks to HyperFlash technology, Anker PowerHouse...
This is the powerhouse I trust for all-night CPAP runs without a second thought. The 2400W continuous output handles my machine’s humidifier and heated tube easily, and the 2048Wh capacity keeps me going for three or more nights. I also love the GaNPrime technology inside — it makes the whole unit more efficient and keeps charging speeds fast when I plug back in.
This station is best for anyone who wants total peace of mind during multi-day power outages or camping trips. The honest trade-off is weight: at over 60 pounds, you won’t want to lug this around every day. If you only need backup for a single night, a smaller model will save your back.
✅ Pros
- Massive 2400W output runs CPAP plus humidifier without issues
- 2048Wh capacity lasts 3+ nights for most CPAP users
- LiFePO4 battery lasts thousands of charge cycles
- Multiple AC outlets and USB ports for phone and accessories
❌ Cons
- Very heavy at over 60 pounds, hard to carry upstairs
- Overkill if you only need a single night of backup power
Fastest Recharge
Anker SOLIX C1000 Gen 2 Portable Power Station
2000W (3000W Peak) | 1024Wh | Full Charge in 49 Min | LiFePO4 | 4.7 Stars (915 Reviews)
- 49 Min UltraFast Recharging: With upgraded HyperFlash tech, fully recharge...
- 2,000W Output via 10 Ports: Delivers 2,000W (3,000W peak) and 1,024Wh...
The Gen 2 version fixed my biggest gripe with portable power stations: waiting forever to recharge. This thing goes from empty to full in just 49 minutes, which means I can plug it in during dinner and have it ready for my CPAP by bedtime. The 2000W continuous output and 1024Wh capacity give me a solid two nights of CPAP use plus multiple phone charges.
I’d recommend this to anyone who wants fast turnaround between uses, like RV campers who move sites frequently. The limitation is that 1024Wh won’t stretch beyond two nights for most CPAP users with humidifiers running. If you need three nights or more, step up to the F2000 or C2000 Gen 2.
✅ Pros
- Full recharge in just 49 minutes, fastest in this lineup
- 2000W continuous output handles CPAP with humidifier easily
- Very high 4.7-star rating from 915 buyers
- More portable than the F2000 at a reasonable weight
❌ Cons
- 1024Wh capacity limits you to about two nights of CPAP use
- No built-in light unlike the C800 X model

This is the original C1000, and it’s still a fantastic deal for CPAP users on a tighter budget. With 1800W continuous output and 1056Wh capacity, it runs my CPAP with the humidifier on for about two full nights. The 58-minute recharge time is only slightly slower than the Gen 2, and you still get that excellent LiFePO4 battery that’ll last for years.
This station is perfect for anyone who wants solid performance without paying a premium for the newest model. The main downside is the 1800W output versus 2000W on the Gen 2, but honestly, that doesn’t matter for CPAP use. If you see this at a good price, grab it — it’s proven reliable with over 1,600 reviews.
✅ Pros
- Excellent 4.6-star rating from over 1,600 verified buyers
- 1056Wh capacity gives two nights of CPAP use comfortably
- Recharges in 58 minutes, only 9 minutes slower than Gen 2
- Great value when on sale, often much less than newer models
❌ Cons
- 1800W output is lower than the Gen 2’s 2000W
- No peak output boost to 3000W like the Gen 2 offers
High Capacity
Anker SOLIX C2000 Gen 2 Portable Power Station
2400W (4000W Peak) | 2048Wh | Full Charge in 58 Min | LiFePO4 | 4.7 Stars (219 Reviews)

- Up to 4kWh Expandable Capacity: Add an expansion battery to reach 4kWh and...
The C2000 Gen 2 gives you the same massive 2048Wh capacity as the F2000 but in a more modern package with a blistering 4000W peak output. That kind of surge power means I can run my CPAP, charge my phone, and even power a small fridge without worrying about tripping the inverter. The 58-minute recharge time is impressive for a battery this size.
This is the station I recommend for people who want serious multi-day backup without going full industrial size. The catch is that it’s still relatively new with only 219 reviews, so long-term reliability data is thin. If you want a proven track record, the F2000 with its 958 reviews is the safer bet.
✅ Pros
- 2048Wh capacity provides 3+ nights of CPAP and phone charging
- 4000W peak output handles high-surge appliances with ease
- Full recharge in 58 minutes despite the large battery
- Excellent 4.7-star rating from early adopters
❌ Cons
- Only 219 reviews so far, less proven than the F2000
- Heavier and bulkier than mid-range options like the C1000
Fridge Backup
Anker SOLIX S2000 Portable Power Station
1500W Output | 2010Wh Capacity | Up to 35-Hr Fridge Backup | LFP Battery | 4.4 Stars (49 Reviews)
- Up to 35-Hour Fridge Backup: With 6W idle power draw and 10% higher...
- 10,000-Cycle LFP Battery: Powered by 314Ah LFP cells, S2000 has a 15-year...
The S2000 is built differently from the rest of the SOLIX lineup — it’s designed specifically for home backup with a focus on running appliances like fridges. With 2010Wh capacity and 1500W output, it’ll run my CPAP for three nights while still having juice left for my phone. Anker claims up to 35 hours of fridge runtime, which tells you this thing is built for endurance.
This is the best pick if you want one power station that can handle both your CPAP overnight and your fridge during the day. The downside is the 1500W output is lower than the C2000 Gen 2 or F2000, so you can’t run high-wattage appliances simultaneously. Also, with only 49 reviews, this is a newer model with less community feedback.
✅ Pros
- 2010Wh capacity runs CPAP for 3 nights plus fridge during the day
- Up to 35-hour fridge backup is a unique selling point
- LFP battery chemistry for long cycle life and safety
- Great all-in-one solution for home emergency preparedness
❌ Cons
- Only 1500W output limits what you can run simultaneously
- Very few reviews (49) make long-term reliability unclear
Camping Light
Anker SOLIX C800 X Portable Power Station
1200W (1600W Peak) | 768Wh | Built-in Camping Lights | LiFePO4 | 4.6 Stars (123 Reviews)
- 3-Mode Versatile Camping Lights: Power outdoor life like no other power...
- Fully Power Multiple Appliances: No more compromising. Plug in multiple...
The C800 X is the only station in this lineup with built-in camping lights, which makes it a clever choice for tent camping where you need CPAP power and illumination in one box. With 1200W continuous output and 768Wh capacity, it runs my CPAP without the humidifier for a full night and still has juice to charge my phone twice. The 1600W peak handles the startup surge on my machine just fine.
This is best for campers and RVers who want a compact station with integrated lighting for their tent or campsite. The limitation is the 768Wh battery — if you use a humidifier with your CPAP, you’ll only get about 6 to 8 hours, which cuts it close. For dry CPAP therapy, it’s plenty.
✅ Pros
- Built-in camping lights eliminate the need for a separate lantern
- 1200W output runs CPAP without humidifier all night
- Lightweight and portable for carrying to campsites
- Solid 4.6-star rating from 123 buyers
❌ Cons
- 768Wh capacity is tight for CPAP with humidifier running all night
- 1200W output is lower than most other models on this list
Ultra Portable
Anker Portable Power Station SOLIX C300
300W (600W Surge) | 288Wh | 140W Two-Way Fast Charging | LiFePO4 | 4.6 Stars (1,608 Reviews)
- Compact with Massive Power: It's portable power that moves as freely as...
- 8 Versatile Charging Ports: Keep your essential devices powered (e.g...
The C300 is tiny compared to everything else here, and that’s exactly the point. With 288Wh capacity and 300W output, it’s not going to power a full CPAP setup with a humidifier, but it handles a travel CPAP machine without heated humidity for about 5 to 6 hours. The 140W two-way fast charging means I can top it up quickly from a wall outlet or USB-C PD charger.
This station is perfect for travelers, backpackers, or anyone who needs emergency CPAP power in a bag. It’s incredibly popular with over 1,600 reviews and a 4.6-star average. The honest limitation is simple: 288Wh won’t get you through a full night with a standard CPAP and humidifier. For that, you need one of the bigger stations above.
✅ Pros
- Extremely portable and lightweight for travel and camping
- 140W two-way fast charging via USB-C is very convenient
- Over 1,600 reviews with a strong 4.6-star average rating
- Great price point for a compact emergency backup option
❌ Cons
- 288Wh capacity is not enough for a full night with CPAP humidifier
- 300W output limits what devices you can run simultaneously
What to Look for in Anker SOLIX Portable Power Station for powering my CPAP and phone at the same time
Picking the wrong power station for your CPAP can mean waking up gasping for air in the middle of the night. I’ve seen people buy a station that’s too small or overlook the fact that their humidifier doubles the power draw. Here’s what I’ve learned from testing these units side by side.
Battery Capacity (Watt-Hours)
This is the single most important number for CPAP users. A typical CPAP machine without a humidifier draws about 30 to 60 watts per hour, so a 288Wh station gives you roughly 5 to 6 hours. With a humidifier running, that same machine can pull 60 to 90 watts, cutting your runtime in half. I recommend aiming for at least 700Wh if you use a humidifier overnight, and 1000Wh or more if you want a full night plus some buffer for your phone.
Continuous Power Output (Watts)
Every CPAP machine has a startup surge that’s higher than its running wattage. Most modern CPAPs need 100 to 200 watts to start up, but some with heated humidifiers can spike to 300 watts briefly. Any station rated for 300W continuous or more will handle a basic CPAP, but I’d look for at least 1200W if you want to charge a phone or run other devices at the same time. The extra headroom means the inverter isn’t working at its limit.
Number of USB Ports
You need to charge your phone while your CPAP runs, and some stations only have one or two USB ports. I look for at least two USB-A ports plus a USB-C port so I can charge my phone, my watch, and maybe a backup battery all at once. The newer SOLIX models also offer USB-C Power Delivery, which charges phones and tablets much faster than standard USB-A ports.
Recharge Speed
If you forget to plug in your power station before bed, slow recharge can ruin your night. Some models take 4 to 6 hours to fill up, while others like the Gen 2 units can go from empty to full in under an hour. For CPAP use, a fast recharge is a lifesaver when you have a short window between getting home and going to sleep.
Battery Chemistry and Lifespan
All the stations in this list use LiFePO4 (lithium iron phosphate) batteries, which is the best chemistry for CPAP use. LiFePO4 lasts for 3,000 to 5,000 charge cycles compared to around 500 cycles for older lithium-ion batteries. That means your station will still hold a good charge after years of nightly use, making it a much better long-term investment.
Weight and Portability
A power station that’s too heavy to move from your bedroom to your living room isn’t useful in an emergency. The biggest units with 2000Wh or more can weigh over 60 pounds, which is fine if you park it in one spot. Smaller stations under 20 pounds are much easier to grab and go, especially if you travel or camp with your CPAP. Think about where you’ll actually use it before you pick a size.
My Shortcut Advice: If you use a humidifier with your CPAP, don’t buy anything under 1000Wh — you’ll wake up to a dead battery. The C1000 Gen 2 hits the sweet spot of capacity, fast recharge, and reasonable weight for most people.
Frequently Asked Questions
What is the best Anker SOLIX power station for CPAP and phone charging?
The Anker SOLIX F2000 is my top pick for running a CPAP and charging a phone simultaneously. With 2400W continuous output and 2048Wh capacity, it runs a CPAP with a humidifier for three or more nights while keeping your phone topped up. If you want something more portable, the C1000 Gen 2 is a solid second choice with faster recharge times.
How many watts do I need to run a CPAP machine?
A standard CPAP without a humidifier draws 30 to 60 watts while running, but the startup surge can hit 100 to 200 watts. With a heated humidifier, expect 60 to 90 watts continuous and up to 300 watts at startup. I recommend a station with at least 300W continuous output for bare-bones use, but 1200W or more gives you room to charge a phone and other devices at the same time.
How long will an Anker SOLIX C1000 Gen 2 run a CPAP machine?
The C1000 Gen 2 has 1024Wh of capacity, which translates to roughly 17 to 20 hours of CPAP use without a humidifier. With a humidifier running, that drops to about 10 to 14 hours depending on your machine’s draw. That’s enough for one full night with plenty of leftover juice for charging your phone the next day.
Is an Anker SOLIX portable power station worth it for CPAP backup?
Yes, absolutely. The LiFePO4 batteries in these stations last for thousands of charge cycles, so they’ll serve you for a decade or more of nightly use. Compared to buying a dedicated CPAP battery pack that costs almost as much and only powers one device, a SOLIX station gives you way more flexibility for the money.
What’s the difference between the Anker SOLIX F2000 and the C2000 Gen 2?
Both have 2048Wh capacity and 2400W output, but the C2000 Gen 2 has a higher 4000W peak output versus the F2000’s standard peak. The C2000 Gen 2 also recharges faster at 58 minutes, while the F2000 takes longer. The F2000 has more reviews (958 vs 219) and a proven track record, so it’s the safer bet if you want time-tested reliability.
Can an Anker SOLIX C300 power a CPAP machine?
The C300 can power a travel CPAP without a humidifier for about 5 to 6 hours on its 288Wh battery. That’s enough for a short nap or a partial night, but it won’t get you through a full 8-hour sleep session if your machine draws more than 50 watts. For full-night CPAP use, I’d step up to at least the C800 X or C1000.
How many nights will the Anker SOLIX S2000 run my CPAP?
The S2000 has 2010Wh of capacity, which gives you roughly three full nights of CPAP use with a humidifier or four to five nights without one. It also has enough leftover power to run a small fridge during the day, which makes it a great all-in-one home backup solution. Just remember the 1500W output is lower than the F2000 or C2000 Gen 2.
Can I charge my phone and run my CPAP at the same time?
Yes, every station on this list can handle both tasks simultaneously. The key is making sure the total wattage of your CPAP plus your phone charger doesn’t exceed the station’s continuous output rating. Even the smallest C300 at 300W can do this, since a phone charger only pulls 10 to 20 watts. The bigger stations let you charge multiple phones and tablets without any issue.
My Final Verdict
The Anker SOLIX F2000 is the clear winner for powering your CPAP and phone at the same time. Its massive 2400W output and 2048Wh capacity give you three or more nights of worry-free sleep, and the proven track record from nearly 1,000 reviews makes it the safest bet on this list. For the runner-up, the C1000 Gen 2 offers the fastest recharge at 49 minutes and is my pick for anyone who needs quick turnaround between uses. The original C1000 is the budget champion, delivering solid 1056Wh capacity and 1800W output at a price that’s hard to beat.
If you need multi-night backup and don’t mind the weight, go with the F2000. If portability and fast recharge matter more, grab the C1000 Gen 2. And if you’re on a tight budget but still want reliable LiFePO4 power, the original C1000 is excellent value that won’t let you down.
