EcoFlow DELTA Pro 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
Bluetti Apex 300 costs $1600 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 30% more energy (3600Wh vs 2764Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 480W more surge headroom (7680W vs 7200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti Apex 300 is 19.6 lb lighter (79.4 lb vs 99 lb).
- Bluetti Apex 300 is rated for 6,000 cycles vs 3,500 — meaningful if you cycle it daily.
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
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
