The short answer
EcoFlow DELTA 3 Max Plus costs $400 less. Whether that gap is worth closing depends on what you need to run.
- Pecron E3600LFP holds 46% more energy (3000Wh vs 2048Wh), so it runs the same load proportionally longer.
- Pecron E3600LFP has 1000W more surge headroom (7000W vs 6000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Max Plus is 19.7 lb lighter (57.3 lb vs 77 lb).
- EcoFlow DELTA 3 Max Plus is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.

- 57 lb
Pecron E3600LFP
A 3kWh unit with 3,600W output and 2,500W solar input at a price well below the flagship majors — strong specs, smaller brand.
