Anker SOLIX F2000 vs EcoFlow DELTA mini
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 mini costs $1100 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2000 holds 132% more energy (2048Wh vs 882Wh), so it runs the same load proportionally longer.
- Anker SOLIX F2000 has 1500W more surge headroom (3600W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 24.4 lb lighter (23.6 lb vs 48 lb).
- Anker SOLIX F2000 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX F2000 is rated for 3,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA mini. 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.
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
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
