EcoFlow DELTA Pro 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
Anker SOLIX F2000 costs $1500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 76% more energy (3600Wh vs 2048Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 3600W more surge headroom (7200W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX F2000 is 51.0 lb lighter (48 lb vs 99 lb).
- EcoFlow DELTA Pro is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
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
