EcoFlow DELTA 2 vs Anker SOLIX C2000
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow DELTA 2 costs $400 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX C2000 holds 100% more energy (2048Wh vs 1024Wh), so it runs the same load proportionally longer.
- Anker SOLIX C2000 has 1400W more surge headroom (3600W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 21.5 lb lighter (27 lb vs 48.5 lb).
EcoFlow DELTA 2
The value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
Anker SOLIX C2000
2048Wh at $1299 with fast 70-minute charging. Sits between the C1000 and the F-series without a standout spec of its own.
Best for: Anker loyalists who want 2kWh and fast charging in one box.
Where it falls short:
- 3600W surge trails the DELTA 3 Max's 4800W at a higher price
- 3000 cycles vs 4000 from newer rivals
