Anker SOLIX C2000 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 $700 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX C2000 holds 132% more energy (2048Wh vs 882Wh), so it runs the same load proportionally longer.
- Anker SOLIX C2000 has 1500W more surge headroom (3600W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 24.9 lb lighter (23.6 lb vs 48.5 lb).
- Anker SOLIX C2000 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX C2000 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.
2048Wh at $1299 with fast 70-minute charging. Sits between the C1000 and the F-series without a standout spec of its own.
Best for: Anker loyalists who want 2kWh and fast charging in one box.
Where it falls short:
- 3600W surge trails the DELTA 3 Max's 4800W at a higher price
- 3000 cycles vs 4000 from newer rivals
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
