Full-size refrigerator
Uses 500 W and 33% duty cycle for both stations.
Source-aware comparison
Anker SOLIX C1000 vs EcoFlow DELTA 2
A source-backed comparison with neutral, spec-derived verdicts. Unknown fields stay visible, and both stations use the same runtime assumptions.
Compare This Pair For A Real Load
Scenario pages apply one source-backed device load to both stations before you inspect the full table.
CPAP without heated humidifier
Uses 40 W and 100% duty cycle for both stations.
Anker SOLIX C1000
1,056 Wh, 1,800 W AC output.
Confidence: verified. Last verified: 2026-06-24.
EcoFlow DELTA 2
1,024 Wh, 1,800 W AC output.
Confidence: verified. Last verified: 2026-06-24.
Capacity
Capacity: C1000 is higher by 32 Wh.
AC Output
AC output: both records are equal at 1,800 W.
Solar Input
Solar input: C1000 is higher by 100 W.
The 60 W runtime estimate assumes AC output, 85% conversion efficiency, and 10% battery reserve. It is a sanity check, not a lab-tested result.
Which one, when?
These verdicts are computed only from tracked specs. They do not use price, affiliate status, ads, sponsorships, or untracked preferences.

Planning Watch-Outs
These checks explain where the comparison is strong and where it still needs better source coverage.
- 5 of 5 high-impact comparison fields are filled on both sides.
- C1000 has the larger nominal battery capacity, but usable Wh still depends on reserve, efficiency, temperature, and battery age.
- DELTA 2 is lighter in the tracked weight data, which matters if the station is moved often.
- C1000 has the higher tracked solar input, assuming compatible panels and charge-voltage limits.
