EcoFlow DELTA 3 Ultra vs Dabbsson DBS2300
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 DBS2300 costs $400 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra holds 32% more energy (3072Wh vs 2330Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Ultra has 2800W more surge headroom (7200W vs 4400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Dabbsson DBS2300 is 29.5 lb lighter (54.3 lb vs 83.8 lb).
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
Dabbsson DBS2300
An expandable 2.3kWh with an unusually large base capacity for its price, and a huge expansion ceiling via Dabbsson's add-on batteries.
Best for: Buyers planning a large expandable system on a budget.
Where it falls short:
- Smaller brand and support network
- 54.3 lb
