Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow RIVER 3 costs $2060 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 1311% more energy (3456Wh vs 245Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 5400W more surge headroom (6000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 98.2 lb lighter (7.8 lb vs 106 lb).
- Allpowers R4000 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow RIVER 3
A glorified power bank with AC outlets — and that's fine if that's what you need. 245Wh runs devices, not appliances.
Best for: Weekend campers charging phones, cameras and a laptop.
Where it falls short:
- 300W output rules out anything with a heating element
- No expansion path
Allpowers R4000
A large expandable unit that undercuts the EcoFlow Delta Pro 3 on price while matching its 4,000W output — the trade is a less established support network.
Best for: Whole-home backup buyers prioritising price per watt over brand.
Where it falls short:
- 106 lb
- Brand support and resale trail the big names
