Anker SOLIX C1000 vs EcoFlow DELTA Pro
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 $2200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 241% more energy (3600Wh vs 1056Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 4800W more surge headroom (7200W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C1000 is 70.6 lb lighter (28.44 lb vs 99 lb).
- EcoFlow DELTA Pro is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
Anker SOLIX C1000
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
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
