EcoFlow DELTA 3 vs Bluetti Apex 300
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 costs $950 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti Apex 300 holds 170% more energy (2764Wh vs 1024Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 4080W more surge headroom (7680W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 is 50.7 lb lighter (28.7 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
The 1kWh class got a serious upgrade here. 3600W surge at $649 beats the older DELTA 2 on every axis that matters.
Best for: Anyone about to buy a DELTA 2 — this is the same money for materially better specs.
Where it falls short:
- Still only 1024Wh
- Solar input unchanged at 500W
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
