Specs side by side
| Spec | Anker SOLIX C1000 | EcoFlow DELTA 2 |
|---|---|---|
| Rated capacity | 1,056 Wh[source]Tech Specs 'Capacity: 1056Wh'. This is the original C1000 (A1761), not the C1000X (separate page, /products/a1761111) or the C1000 Gen 2 (1,024 Wh). The US page shows the unit as 'Sold Out' on 2026-10-18. | 1,024 Wh[source]Specs tab: 'Capacity 1024 Wh'. Manual: '1,024Wh, 51.2V'. The official US info page still exists, but the us.ecoflow.com store URL (/products/delta-2-portable-power-station) now redirects to the DELTA 3, so the unit is no longer sold standalone on the official US store. |
| Usable capacity (measured) | 897 Wh[source]OutdoorGearLab (US unit, AC output) measured 897 Wh, about 85% of rated. ComputerBase (EU 230 V unit) measured 993 Wh at 500 W and 954 Wh at 2,000 W; the lower figure is used. | 850 Wh[source]StorageReview measured 0.85 kWh through AC at a 270 W load (120 V unit). EU 230 V units tested higher: nextpit 901 Wh at about 1,000 W; techtest.org 826 Wh (AC 125 W) and 903 Wh (AC 750 W). Lowest figure used. |

Runtime = usable capacity ÷ average draw, the same formula for both models (no idle draw added to either), after checking continuous output and startup surge. Usable capacity is an independent test's measured figure, or 80% of rated where none exists. See the methodology.
