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 $800 less. Whether that gap is worth closing depends on what you need to run.
- Pecron E3600LFP holds 193% more energy (3000Wh vs 1024Wh), so it runs the same load proportionally longer.
- Pecron E3600LFP has 4800W more surge headroom (7000W vs 2200W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 2 is 50.0 lb lighter (27 lb vs 77 lb).
- Pecron E3600LFP is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA 2
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
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.
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
