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 3 Max costs $500 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti Apex 300 holds 35% more energy (2764Wh vs 2048Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 2880W more surge headroom (7680W vs 4800W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Max is 24.3 lb lighter (55.1 lb vs 79.4 lb).
- Bluetti Apex 300 is rated for 6,000 cycles vs 4,000 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Max
The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
Where it falls short:
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
Bluetti Apex 300
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
