If you rely on a CPAP machine every night, choosing the right portable power station is about far more than convenience. During a power outage, camping trip, or off-grid adventure, dependable backup power can make the difference between uninterrupted sleep and a stressful night.
That’s why many buyers compare the Anker SOLIX C1000 Gen 2 vs Jackery Explorer 1000 V2 for CPAP backup before spending hundreds of dollars. Both offer roughly 1kWh of battery capacity, fast charging, and solar compatibility.
However, they differ in charging speed, UPS performance, real-world CPAP runtime, connectivity, and user experience. This comparison combines technical specifications with dozens of real customer experiences to help you decide which one better fits your needs.

CPAP Runtime Comparison
Runtime depends on:
- CPAP model
- Humidifier use
- Heated hose
- AC vs DC adapter
Real-world reports strongly favor using a DC adapter whenever possible because it avoids inverter losses.
Anker SOLIX C1000 Gen 2
Users commonly reported:
- 2–4 nights with efficient DC setups
- Around 15–17% battery used per night
- One user powered a CPAP for four consecutive nights
- Another successfully powered two CPAP machines for an entire weekend while still retaining roughly half the battery.
