EcoFlow RIVER 2 Pro 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 RIVER 2 Pro costs $1100 less. Whether that gap is worth closing depends on what you need to run.
- Pecron E3600LFP holds 291% more energy (3000Wh vs 768Wh), so it runs the same load proportionally longer.
- Pecron E3600LFP has 5400W more surge headroom (7000W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Pro is 60.0 lb lighter (17 lb vs 77 lb).
- Pecron E3600LFP is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
The one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
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
