EcoFlow RIVER 2 costs $1500 less. Whether that gap is worth closing depends on what you need to run.

- Pecron E3600LFP has 6400W more surge headroom (7000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.

- Pecron E3600LFP is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow RIVER 2
The cheapest way into LiFePO4. 256Wh is a device charger, but at under $200 with a 60-minute recharge it's hard to argue with.
Best for: Budget campers who just need to keep phones, cameras and a laptop alive.
Where it falls short:
- 300W output runs devices only
- 256Wh is a single evening of real use
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
