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
Dabbsson DBS1000 costs $1300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra Plus holds 200% more energy (3072Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra Plus has 3200W more surge headroom (7200W vs 4000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Dabbsson DBS1000 is 60.5 lb lighter (25 lb vs 85.5 lb).
- Dabbsson DBS1000 is rated for 4,500 cycles vs 4,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Ultra Plus
The Ultra's solar problem solved: same everything, but 1600W of PV input instead of 800W. That doubles your off-grid refill speed for $200.
Best for: Off-grid cabins and van builds that actually recharge from panels.
Where it falls short:
- $1999 approaches DELTA Pro 3 pricing
- 85.5 lb
Dabbsson DBS1000
A 1kWh with a 4,000-cycle rating and expandability at a mid price — a credible value alternative to the mainstream 1kWh units.
Best for: Value buyers who want long cycle life and expansion at 1kWh.
Where it falls short:
- Smaller brand and support network
- Smaller support network
