EcoFlow DELTA 2 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
EcoFlow DELTA 2 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 23% more energy (1260Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 1100W more surge headroom (3300W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 3.9 lb lighter (27 lb vs 30.9 lb).
- EcoFlow DELTA 2 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 2 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 value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
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
