Anker SOLIX C800 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
Anker SOLIX C800 costs $400 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 64% more energy (1260Wh vs 768Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 1700W more surge headroom (3300W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C800 is 6.0 lb lighter (24.9 lb vs 30.9 lb).
- Anker SOLIX C800 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker SOLIX C800 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 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.
The C1000's smaller sibling. Same fast-charging DNA at a lower price, but the 768Wh capacity puts it firmly in weekend-trip territory.
Best for: Campers and van-lifers powering electronics, lights and a mini fridge — not home backup.
Where it falls short:
- 300W solar input is low — slow to top off off-grid
- 1600W surge rules out most motor-driven appliances
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
