The BLUETTI Elite 30 V2 is the best overall pick: a light, quiet backup with UPS-style switchover that is well suited to CPAP backup and travel. At 9.5 lbs (4.3kg) it is small enough to fit in a backpack, which makes it a strong choice for travelers.

The specs that matter for CPAP are all here. The UPS switchover is ≤10ms, so the unit can keep your machine running through an outage. Operation is rated at 30dB, which suits a bedroom. The LiFePO4 battery is rated for 3,000+ cycles and the warranty is 5 years. It also charges many ways, including AC, solar and car, and its 140W USB-C port can charge a laptop or other modern devices. Reviewers have rated it well: BackupPowerHub gave it 8.4 out of 10, TechRadar 4.5 out of 5 and CGMagazine 9 out of 10.
The main trade-off is capacity. At 288Wh, it limits how many nights it can run a CPAP, and 600W of output is too low for large appliances. It is best for overnight backup or short trips rather than long off-grid stays. If you want to be away from a wall outlet for several nights, look at the next pick.
EcoFlow RIVER 2 Max 500: Best Value for Multi-Night CPAP

The EcoFlow RIVER 2 Max 500 is the best value pick for buyers who want more runtime than a compact unit offers without moving up to a large, heavy station. Its 499Wh LiFePO4 battery gives more CPAP runtime than smaller units, and it weighs 13.2 lbs. It is aimed at people who want multi-night CPAP power at a fair price.

It recharges fully in 60 minutes from a wall outlet (0-100% via 660W AC input), so it is quickly ready again after an outage. The UPS auto-switch is under 30ms and supports CPAP and home backup. You also get Wi-Fi and Bluetooth app control for remote monitoring, TÜV Rheinland safety certification and a 5-year warranty. The battery is rated for 3,000 cycles, or 10 years of typical use. It has four charging methods: AC, car, solar (220W max) and USB-C (100W). Expert scores include BackupPowerHub at 8.2 out of 10 and AndroidCentral and CameraJabber at 4.5 out of 5 each.
The trade-offs are weight and output. At 13.2 lbs it is heavier than the most compact options, and 500W of continuous output (1,000W surge with X-Boost) limits use with higher-wattage appliances. Its switchover is also slower than the 10ms-class units in this guide, though still under 30ms.

Keep reading about Jackery Explorer 1000 v2
The 1500W continuous output (3000W surge) powers CPAP machines and most household appliances. The LiFePO4 battery is rated for 4000 cycles to 70%+ capacity, and the warranty is 5 years (3 + 2 years free on Jackery.com). Recharging is quick: Emergency Super Charge mode reaches full in 1 hour via the app, or 1.58 hours on standard AC. Solar input goes up to 400W with a built-in MPPT controller. Reviewers rate it well, with Energia Solar Pro at 8.9 out of 10, Off Grid Benchmark at 8.5 out of 10 and Outdoor Tech Lab at 4.6 out of 5.
It is a lot of station for a CPAP. At 23.8 lbs it is heavy for backpack or travel use, and its capacity is larger than a CPAP alone usually needs. Its listed specs also do not include a UPS switchover time, so if seamless switchover during an outage matters to you, confirm that on the manufacturer's page. It suits home backup and camping better than light travel.
EcoFlow DELTA 3: Also Great for Expandable Home Backup
Best for: Home users wanting expandable backup beyond CPAP
A powerful, expandable station with fast charging and quick UPS switching. It makes sense if you want CPAP backup that can grow into whole-home essentials.

It charges fully in 56 minutes with 1500W AC input, and recharging options include AC, solar, alternator, generator and multi-charging. The UPS switch time is under 10ms, which helps protect continuous operation. Battery life is rated at 4000 cycles to 80% capacity, and the warranty is 5 years. Portable Power Nerd scored it 9.2 out of 10, Backup Power Hub gave it 8.4 out of 10 and Outdoor Gear Lab rated it 4.3 out of 5.
The cost of all that is bulk. At 27.6 lbs it is the heaviest unit here, and its power and expansion options exceed what a CPAP alone needs. If your only goal is overnight CPAP backup, you will be paying for headroom you may not use. It is best for people who also want to run other essentials during an outage.

Keep reading about Anker SOLIX C1000 Gen 2
It provides 2,000W of continuous output (3,000W peak) from a 1,024Wh battery, enough to power a CPAP alongside refrigerators and most appliances. The UPS switchover is 10ms, which suits sensitive medical devices. Solar input goes up to 600W, and the battery is rated for 4,000 cycles to 80% capacity with a 5-year warranty. It has 10 ports, including three USB-C ports rated up to 140W each. Backup Power Hub scored it 9 out of 10, Outdoor Gear Lab 8.5 out of 10 and How-To Geek 8 out of 10, and MacRumors gave it 4.5 out of 5.

How to Choose the Best Power Station for CPAP
Start with capacity
Capacity, measured in watt-hours (Wh), sets how long a station can run your machine. A larger battery means more nights between recharges. Your CPAP's actual draw varies by model and settings, and a heated humidifier typically increases it, so check your machine's power rating and your device manufacturer's guidance before choosing. Among these picks, the BLUETTI Elite 30 V2 (288Wh) suits overnight or short-trip use. The RIVER 2 Max 500 (499Wh) steps up to multi-night use. The Jackery, DELTA 3 and Anker units are all in the 1kWh class.
Check the switchover
If you want your CPAP to keep running when mains power drops, look for a listed UPS switchover time. The Elite 30 V2 lists ≤10ms, the DELTA 3 under 10ms, the Anker SOLIX C1000 Gen 2 10ms and the RIVER 2 Max 500 under 30ms. The Jackery Explorer 1000 v2's listed specs do not include a switchover time.
Weigh portability against headroom
Weight ranges from 9.5 lbs to 27.6 lbs across these picks. If you fly or pack a bag, the lightest units matter. If the station stays on a nightstand or in a closet, the heavier 1kWh-class units give you more runtime and power for other devices. Extra output, such as 1500W to 2,000W, is only useful if you plan to run other appliances with your CPAP.
Consider recharge speed and options
Fast recharging helps after an outage or when you are moving between campsites. Listed full-recharge times in this guide range from 49 minutes (Anker, UltraFast AC mode) to 70 minutes (Elite 30 V2, 100%). Solar input also varies, from 200W on the Elite 30 V2 to 600W on the Anker. If you plan to use solar for off-grid trips, match the panel to the unit's maximum input.
Look at battery chemistry and warranty
The BLUETTI, EcoFlow RIVER 2 Max 500, Jackery and EcoFlow DELTA 3 use LiFePO4/LFP batteries, and all five picks list 5-year warranties. Rated cycle life is 3,000+ cycles to 80% on the BLUETTI and EcoFlow RIVER 2 Max 500, 4000 cycles to 80% on the DELTA 3, 4,000 cycles to 80% on the Anker, and 4000 cycles to 70%+ on the Jackery.
How We Picked
We compared these five picks using manufacturer specs and independent expert scores. We looked at the factors that matter most for CPAP backup: battery capacity, weight, UPS switchover, recharge speed, warranty and what reviewers consistently say. We have not tested these units ourselves. Labels reflect each product's role in this lineup, and the Best Budget label is relative to the units compared here. Always confirm your own CPAP's power requirements before buying.
Bottom Line
For most CPAP users, the BLUETTI Elite 30 V2 is the best power station for CPAP backup and travel: light, quiet and quick to switch over, with the caveat that its 288Wh capacity suits short stays. If you need more nights of runtime, the EcoFlow RIVER 2 Max 500 offers more capacity in a still-portable package. For long outages, camping or powering other devices, step up to the Jackery Explorer 1000 v2. Choose the EcoFlow DELTA 3 if you want expandable home backup, or the Anker SOLIX C1000 Gen 2 if recharge speed and high output matter most.
