EcoFlow DELTA 3 Plus 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 3 Plus costs $250 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 3 Plus has 300W more surge headroom (3600W vs 3300W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Plus is 2.2 lb lighter (28.7 lb vs 30.9 lb).
- EcoFlow DELTA 3 Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Plus is rated for 4,000 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 DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
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
