EcoFlow DELTA 3 Ultra Plus vs Oukitel BP2000
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
Oukitel BP2000 costs $700 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Ultra Plus holds 50% more energy (3072Wh vs 2048Wh), 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.
- Oukitel BP2000 is 33.5 lb lighter (52 lb vs 85.5 lb).
- EcoFlow DELTA 3 Ultra Plus is rated for 4,000 cycles vs 3,500 — 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
Oukitel BP2000
A value-brand 2kWh that competes almost entirely on price, routinely undercutting the majors by hundreds while matching their core specs on paper.
Best for: Bargain-focused buyers who want 2kWh of expandable backup for the least money.
Where it falls short:
- Weaker service network than the majors
- Resale value is lower
