Anker SOLIX C1000 vs EcoFlow DELTA 3 Max Plus
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 C1000 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max Plus holds 94% more energy (2048Wh vs 1056Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max Plus has 3600W more surge headroom (6000W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C1000 is 28.9 lb lighter (28.44 lb vs 57.3 lb).
- EcoFlow DELTA 3 Max Plus is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The default recommendation for most people. It clears the 1kWh bar, recharges in under an hour, and undercuts almost everything with comparable specs.
Best for: First-time buyers who want one unit for camping and short outages without overpaying.
Where it falls short:
- 2400W surge won't start a sump pump or well pump
- Only 1056Wh — a fridge-plus-devices outage tops out around a day
Adds 600W of continuous output and doubles surge headroom over the standard Max, for $200. Worth it only if you're running heavy loads.
Best for: Workshops and job sites where tool startup surge is the constraint.
Where it falls short:
- $200 premium is wasted if your loads are under 2400W
- 57 lb
