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
Allpowers R600 costs $1500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra holds 927% more energy (3072Wh vs 299Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra has 6000W more surge headroom (7200W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Allpowers R600 is 71.0 lb lighter (12.8 lb vs 83.8 lb).
- EcoFlow DELTA 3 Ultra is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Ultra
3kWh with 7200W surge at $1799 — this is whole-home territory at a mid-range price. The catch is the 800W solar input.
Best for: Grid-tied home backup where you recharge from the wall, not the sun.
Where it falls short:
- 800W solar input is low for 3kWh — slow off-grid refills
- 83.8 lb
Allpowers R600
A light, cheap 299Wh unit with a 1,200W surge — a solid budget companion for devices and the occasional small appliance.
Best for: Budget campers charging devices with occasional small-appliance use.
Where it falls short:
- 299Wh is small
- 600W continuous output
