Best overall for portability
Jackery Explorer 1000 v2
Why it ranks here
The lightest selected station offers ample rated capacity for multi-night planning without making a travel or evacuation kit unnecessarily hard to move.
- Direct price
- $549
- Rated capacity
- 1,070 Wh
- Continuous AC
- 1,500 W
- Published peak
- 3,000 W
- Solar input
- 400 W
- Weight
- 23.8 lb
Value context: One of the lower captured direct prices in the 1kWh set. Its strongest value argument is the 23.8 lb carrying weight, not solar throughput.
- Best for
- Users who need multi-night reserve and expect to carry the station.
- Skip it if
- High solar input or a published 10ms transfer claim is the leading requirement.
What works
- Lightest at 23.8 lb
- 1,070Wh rated capacity
- Low captured direct price
Tradeoffs
- Published transfer value is 20ms
- 400W maximum solar input
Best for fast recovery
Anker SOLIX C1000 Gen 2
Why it ranks here
A published 10ms transfer claim and fast AC recharge support a shared emergency kit after the exact CPAP setup has been tested.
- Direct price
- $529.99
- Rated capacity
- 1,024 Wh
- Continuous AC
- 2,000 W
- Published peak
- 3,000 W
- Solar input
- 600 W
- Weight
- 24.9 lb
Value context: A low captured direct price for the highest continuous output in this 1kWh group. The tradeoff is a fixed, non-expandable 1,024Wh capacity.
- Best for
- A home backup kit that powers CPAP plus additional devices and can recharge from the grid quickly.
- Skip it if
- You want expandable capacity or the highest solar input.
What works
- Published 10ms transfer claim
- 49-minute fast-charge claim
- 2,000W continuous output for shared loads
Tradeoffs
- Not treated as a medical UPS certification
- Non-expandable capacity
Best solar-supported option
BLUETTI Elite 100 V2
Why it ranks here
A 10ms-or-less published transfer claim and 1,000W solar input suit a longer backup plan with meaningful daytime recharge.
- Direct price
- $499
- Rated capacity
- 1,024 Wh
- Continuous AC
- 1,800 W
- Published peak
- Not separately published
- Solar input
- 1,000 W
- Weight
- 25.3 lb
Value context: The lowest captured direct price in this 1kWh group, paired with 1,000W solar input. The missing general surge rating remains the main value tradeoff for motor loads.
- Best for
- A home or vehicle-supported CPAP plan with enough panel capacity to recharge during the day.
- Skip it if
- You need the lightest possible station or a separate published general surge rating for other shared loads.
What works
- Published 10ms-or-less transfer claim
- 1,000W maximum solar input
- Lowest captured direct price in the set
Tradeoffs
- 25.3 lb is heavier than Jackery
- UPS timing still requires an exact-device test

Calculation: rated capacity × 80% after reserve × 88% AC efficiency × 95% environmental factor, divided by the cycling average load.
Prescribed pressure, mask leaks, humidifier heat, heated tubing, altitude, and the approved DC converter can change energy use. Test the exact setup before relying on it overnight.
Solar refill floor is rated capacity divided by maximum published solar input. It excludes weather, panel angle, temperature, charge taper, and conversion losses. Runtime does not prove voltage, startup, transfer, wiring, medical, flood-prevention, or combustion safety compatibility.
Research method
How we ranked CPAP backup stations
These are planning recommendations, not medical UPS certifications. The exact machine, prescribed settings, humidifier, heated tube, alarms, and approved power path determine the real order.
We compare official specifications, manuals, support records, current manufacturer pricing, and transparent planning calculations. We do not assign lab scores or claim hands-on testing that did not occur.
- Device-specific energy
- Manufacturer battery tables or measured overnight watt-hours take priority over generic CPAP estimates.
- Transfer behavior
- Published switching claims are noted, then the complete loss-of-power sequence must be tested with the exact therapy setup.
- Reserve nights
- The plan preserves at least one additional night when practical.
- Portability and recharge
- Weight, direct price, solar input, and approved DC options separate otherwise capable models.
