EcoFlow DELTA 1300 vs Pecron E3600LFP
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 1300 costs $700 less. Whether that gap is worth closing depends on what you need to run.
- Pecron E3600LFP holds 138% more energy (3000Wh vs 1260Wh), so it runs the same load proportionally longer.
- Pecron E3600LFP has 3700W more surge headroom (7000W vs 3300W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 1300 is 46.1 lb lighter (30.9 lb vs 77 lb).
- Pecron E3600LFP uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Pecron E3600LFP is rated for 3,500 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 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
A 3kWh unit with 3,600W output and 2,500W solar input at a price well below the flagship majors — strong specs, smaller brand.
Best for: Whole-home backup buyers chasing capacity and solar input per dollar.
Where it falls short:
- 77 lb
- Brand support and resale trail the majors
