CPAP machines are great. Before I owned a CPAP, my oxygen levels were dipping so low when I slept that I was literally damaging my brain. I snored, I frequently woke up in the middle of the night choking and gagging, I usually woke up just as tired as I had been when I had gone to bed, and I used to fall asleep multiple times throughout the day, sometimes at work and sometimes while driving to and from work. Getting a CPAP fixed all of those things for me. It was a game changer. I used mine nightly. It has improved my quality of life.

That being said, there are times when using it is a hassle. I don’t love dragging it on planes or with me on every trip. There’s maintenance and cleaning and supplies that need to be purchased. The biggest hurdle is powering this device that uses 100+ watts/hour while sleeping in a vehicle. When I only owned a 1,000Wh battery, every hour I was asleep the CPAP used 10% of its capacity. I found ways to work around that by adding solar to the roof of my van and charging my battery while driving, but all it took was one bad day for everything to fall off the rails.

The ES960 by EasyLonger is a mid-sized battery designed with CPAP units in mind. In terms of Goldilocks porridge bowls, it’s not too small (like a traditional USB power pack) and not too big (like a full-sized Jackery-style battery). It is “just right.” The ES960 is a 300 watt, 96,000mAh battery designed to run CPAPs. How many nights (or hours) you can squeeze out of the battery depends a bit on your CPAP’s settings.

It’s easiest to think of the ES960 as a USB power pack — or rather, the largest and most rugged USB power pack I’ve ever seen. At 6 1/2 pounds (3kg), you aren’t going to forget that this thing is in your backpack anytime soon. Then again, when compared to my AllPowers R2500 (which weighs 65lbs), the portability of the ES960 becomes more obvious. At a glance, the ES960 almost looks military in design with its black case and brownish/green trim. This unit is solid and while I don’t recommend it, if one were to accidentally drop it on their foot I would be much more worried about the foot than the unit.

Located on the end are grouped inputs and outputs. The unit can be charged via the included 110v adapter (5-6 hours) or USB-C (6-8 hours @60 watts). For outputs the unit has two traditional USB-A ports, one uSB-C (in/out) port, a wireless phone charging port, two full size 12v (15A) ports, and a proprietary port for the included CPAP cables. All of the ports are covered with rubber lids to keep dust, dirt, and spills out when not being used. Inside is a LiFePO4 battery good for 3,000 cycles. A good estimate for fully recharging a modern iPhone is around 5,000mAh, just to put this unit’s 96,000mAh capacity in perspective. On the end opposite of the ports is a dual-LED flashlight, and one has a handle. The front of the unit has a small LCD screen that displays current battery charge in 25% increases, and there are a couple of buttons for operating the unit.

Included in the box are four different adapters for connecting CPAPs to the unit’s DC port. The included adapters are compatible with the following CPAP units: ResMed S9, AirSense 10, AirCurve 10, AirSense11, AirMini, Philips DreamStation, and DreamStation 2. Each adapter is labeled with a different colored tag to make finding the right one simpler. Before using this function, you’ll need to make sure the ES960’s voltage matches your CPAP’s. Changing the voltage is super simple and done by pressing one button on the face of the unit. I believe all ResMed units are 24v and the Phillips Dreamstations are 12v, but if you aren’t sure and don’t have your manual, simply type the model of your CPAP into Google along with “proper voltage” and you will quickly find the answer. I believe other cables are available from the manufacturer, and one could always use a 12v adapter and run a CPAP from the unit’s 12v/15a port as well.

The big question is, will this relatively small battery run your CPAP for an entire night, and the answer, with a couple of caveats, is yes. The two big variables to consider are your air pressure and your humidifier. According to the included documentation and based on an air pressure level of 10cm H20 (this is set by your doctor and should not be changed by you), the ES960 will run a ResMed AirSense 10 for 29 hours with the humidifier and heating tube turned off. With the humidifier on a setting of 4 and the heating tube set to 75F/24C, the ES960 has an estimated run time of 7-12 hours. In a worst case scenario test with the humidifier and heating tube set to auto and my own air pressure setting (a higher than average 16cm), I got five hours of runtime out of the unit the first night I used it. By turning my humidifier and heating tube down on the second night, I was able to get 7 1/2 hours which for me is a full night’s sleep.

Again, the unit’s biggest selling point is its portability. My AllPowers R2500 ((which can run a popcorn machine) has 7x the capacity of EasyLonger’s ES960, but also weighs 65lbs, which is the last thing I want to be dragging along on a hike.

Because the unit is marketed as a portable CPAP battery solution, it’s easy to forget how many uses this thing has. You could easily use it to power a projector while offgrid or recharge your laptop (and probably everything else in your rig) multiple times. When not on the road, having this bedside is great insurance for if (when) the power goes out. If you have ever lost power and spent time in your car with the engine running so you could recharge your phone, owning this will help you sleep at night.

The EasyLonger ES960 is currently available on Amazon for $239. If you use a CPAP in your van, RV or camper and portability is a requirement, this is a good product and a good solution.
