Bluetti Apex 300 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 $1000 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti Apex 300 holds 213% more energy (2764Wh vs 882Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 5580W more surge headroom (7680W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 55.8 lb lighter (23.6 lb vs 79.4 lb).
- Bluetti Apex 300 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Bluetti Apex 300 is rated for 6,000 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.
6000 cycles at 2764Wh — the best long-term cost-per-kWh in this list if you cycle daily. Bluetti's answer to the Elite 200 V2 at scale.
Best for: Off-grid solar setups where daily cycling makes lifespan the dominant cost.
Where it falls short:
- 79.4 lb
- Newer product with limited long-term field data
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
