The short answer
EcoFlow DELTA 3 Max Plus costs $1000 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 69% more energy (3456Wh vs 2048Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max Plus is 48.7 lb lighter (57.3 lb vs 106 lb).
- EcoFlow DELTA 3 Max Plus is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Max Plus
Adds 600W of continuous output and doubles surge headroom over the standard Max, for $200. Worth it only if you're running heavy loads.
Best for: Workshops and job sites where tool startup surge is the constraint.
Where it falls short:
- $200 premium is wasted if your loads are under 2400W
- 57 lb
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
