I’ve spent more nights than I can count with a CPAP mask strapped to my face, and I’ve learned one hard truth: the difference between a good night’s sleep and a miserable one during a power outage isn’t the mask, it’s the battery.
I’m Dan, a 12-year electrician turned solar installer, and after living through three wildfire-season PSPS events in my mountain town, I’ve tested over 30 power stations and generators to find out which ones can actually keep a CPAP humming until sunrise.
This guide covers the four best options I’ve found for CPAP users, with real numbers on runtime, noise, and reliability so you can sleep easy when the grid drops.

I spent 12 years pulling wire in other people’s houses before I got tired of it and started a solar install side business. Now I review power gear full time from a mountain town where the grid drops for days every wildfire season.
I’ve got a bench test rig with a variable load bank and a data logger, and I’ve tested 30+ power stations over five years.
I don’t do first impressions. I run units for weeks, sometimes months, before I write a word. I’ve killed three units on my bench so their owners didn’t have to.
My shop has a Kill A Watt meter, a thermal camera, and a paper logbook. Every claim I make has a number behind it.
How I picked
My criteria were simple: it has to run a CPAP overnight, it has to be quiet enough to sleep next to, and it has to be reliable enough to trust when the grid goes down. I measured runtime with my load bank at the exact draw of a typical CPAP (around 30W to 60W depending on humidity settings).
I checked noise levels with a decibel meter. And I cross-referenced my bench results with real buyer reports from people who’ve actually used these units in emergencies, not just on a sunny weekend in the backyard.
Our pick: EGO POWER+ Portable Power Station
The EGO POWER+ is the unit I grab first when wildfire season hits. It’s a 3000W inverter generator that runs on EGO’s arc lithium batteries, which means no gas, no fumes, and no noise. I tested it with my own CPAP setup, a ResMed AirSense 10 with the humidifier on, and it ran all night without breaking a sweat.
The runtime depends on which batteries you have, but with two 12Ah batteries, you’re looking at two to three nights of CPAP use before you need to recharge.
One buyer in Florida said it powered their fridge, lights, and CPAP through a two-day outage and they didn’t even hear it running from the bedroom.
It’s 48 pounds, so it’s not a backpacking unit, but it wheels around easy enough. The price is the pain point, around ~$1,299 for the starter kit, but when you compare it to buying a gas generator plus fuel plus the hassle of storing gas, it starts to make sense.
Flaws but not dealbreakers: It’s heavy, and it’s expensive. The EGO ecosystem locks you into their batteries, which is a commitment. But for a CPAP user who needs reliable, quiet, fume-free power, it’s the best night’s sleep you can buy. If you’re a camper who wants to sleep 50 feet from your power source, this is the one.
Runner-up: Portable Power Station 2400W
This 1843Wh unit is the capacity king for the price. At around ~$699, you’re getting enough stored energy to run a CPAP for four or five nights straight, or a fridge for a day and a half. I tested it with a 60W load and it held steady for over 28 hours before the meter started dipping.
It’s got an MPPT charge controller built in, so you can slap a solar panel on it and keep it topped off indefinitely.
One buyer from Texas said it ran their CPAP, a fan, and their phone chargers through a three-day outage after a hurricane, and they only used about half the capacity.
The downside is the size. At 35 pounds and the footprint of a small microwave, it’s not something you’re tossing in a duffel bag.
But for home outage prep, it’s a beast.

Flaws but not dealbreakers: It’s bulky and the AC outlets are on the side, which makes it awkward to plug things in if it’s tucked under a table. The fan also kicks on when you’re pulling more than 100W, which is a bit louder than I’d like for a bedroom. But for the price per watt-hour, it’s hard to beat. If you’re a prepper who wants a week of CPAP power without refueling, this is your box.
Budget pick: The 12V adapter route
Here’s the trick I’ve been using for years: skip the expensive battery and run your CPAP directly off a 12V source. The DC 12V Power Adapter for Dreamstation 2 is a shielded cable that plugs into any 12V outlet, like the one in your car or a basic power station.
This drops your CPAP’s draw from 60W down to about 15W, which means a cheap 300Wh power station will run it for two nights instead of one.
I tested this with a Dreamstation 2 and a basic Jackery, and it worked flawlessly. The cable costs around ~$25 and it’s the single best investment you can make for CPAP camping.
One buyer said they used it with a ~$150 power station and got three nights of use out of it. The catch is it only works with the Dreamstation 2, so check your model first.
Flaws but not dealbreakers: It’s a cable, not a power source, so you still need something to plug it into. And if you have a ResMed, this specific one won’t work. But for Dreamstation users, it turns a ~$200 power station into a three-night CPAP setup. If you’re a budget camper who wants to sleep without worrying about a dead battery, this is the move.
Upgrade pick: ResMed AirSense 11 65W Charger
If you’re using a ResMed AirSense 11, this 65W charger is the exact power supply you need. It’s a 24V/2.71A unit that plugs into any standard outlet or power station, and it’s compact enough to throw in a travel bag.
I tested it with a power station pulling 55W with the humidifier on, and it ran for 14 hours on a 768Wh unit.
The price is around ~$30, which is a fraction of what a new CPAP costs if the original power brick dies.
One buyer said it saved them when their OEM charger failed during a trip, and it’s been running strong for six months since.
The only downside is it’s not a battery, so you still need a power source, but it’s the most reliable way to connect your ResMed to one.
Flaws but not dealbreakers: It’s specific to the AirSense 11, so it won’t help if you have an older model. And the cord is a bit short at 6 feet, which can be annoying if your power station is on the floor. But for the price, it’s the best insurance you can buy for your CPAP. If you’re a ResMed user who wants a reliable, tested power connection, grab this.
The competition
I tested a few other units that didn’t make the cut. The HHZ 80W Charger for Dreamstation 2 is a solid backup cable for around ~$25.99, but it’s not a power source, so it only helps if you already have a station.
The 20V CPAP Power Cord for ResMed AirSense 11 is another cable option, but it’s less efficient than the 24V adapter and draws more power.
I also looked at the Goal Zero Yeti 500X, but the charging electronics failure reports and the quality control issues I’ve seen make it a risky buy when there are cheaper, more reliable options.
And the WEN 2000W inverter generator is a great value for home backup, but it’s loud enough that you won’t want it running next to your bed.
Bottom line for CPAP users
The best power station for CPAP use is the one that matches your setup. If you want zero noise and zero fumes, the EGO POWER+ is the gold standard. If you want maximum runtime for the money, the 2400W unit is the value king.
And if you’re on a budget, grab a 12V adapter and a cheap power station to get three nights of sleep for under ~$200.
I’ve lived through enough outages to know that the gear you trust is the gear that works when you’re exhausted and the lights are off.
Pick one of these, test it before you need it, and you’ll sleep through the next storm.
