EcoFlow DELTA 2 vs Anker SOLIX F2000
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 $800 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2000 holds 100% more energy (2048Wh vs 1024Wh), so it runs the same load proportionally longer.
- Anker SOLIX F2000 has 1400W more surge headroom (3600W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 21.0 lb lighter (27 lb vs 48 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 F2000
The older F-series unit, now hard to justify: the C2000 offers the same capacity and surge for $400 less.
Best for: Only worth it if you find it steeply discounted below the C2000.
Where it falls short:
- $1699 is $400 over the newer C2000 with identical core specs
- 105-minute recharge is slow by 2026 standards
