Oukitel BP2000 vs EcoFlow DELTA mini
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
EcoFlow DELTA mini costs $700 less. Whether that gap is worth closing depends on what you need to run.
- Oukitel BP2000 holds 132% more energy (2048Wh vs 882Wh), so it runs the same load proportionally longer.
- Oukitel BP2000 has 1900W more surge headroom (4000W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 28.4 lb lighter (23.6 lb vs 52 lb).
- Oukitel BP2000 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Oukitel BP2000 is rated for 3,500 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA mini. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
