Anker SOLIX F2600 vs EcoFlow DELTA 1300
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 1300 costs $500 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2600 holds 103% more energy (2560Wh vs 1260Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 500W more surge headroom (3300W vs 2800W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 30.8 lb lighter (30.9 lb vs 61.7 lb).
- Anker SOLIX F2600 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX F2600 is rated for 4,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA 1300. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
