EcoFlow DELTA Pro vs Anker SOLIX F2600
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 F2600 costs $1700 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 41% more energy (3600Wh vs 2560Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 4400W more surge headroom (7200W vs 2800W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX F2600 is 37.3 lb lighter (61.7 lb vs 99 lb).
- Anker SOLIX F2600 is rated for 4,000 cycles vs 3,500 — 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 F2600
An odd spec sheet: 2560Wh of capacity but only 2800W surge — the lowest surge-to-capacity ratio here. Capacity without starting power.
Best for: Long-duration backup of steady loads (lights, electronics, CPAP) rather than motor-driven appliances.
Where it falls short:
- 2800W surge is barely above its 2400W continuous — it will struggle with pumps
- 61.7 lb
