EcoFlow DELTA 2 Max 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
These two cost the same, so the decision comes down to what you're powering.
- 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 2 Max is 29.4 lb lighter (50 lb vs 79.4 lb).
- Bluetti Apex 300 is rated for 6,000 cycles vs 3,000 — meaningful if you cycle it daily.
We'd skip the EcoFlow DELTA 2 Max in this matchup. It costs $0 more than the Bluetti Apex 300 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The surge sleeper. At 4800W it starts loads that stations twice its price can't — and most spec sheets bury that number behind the X-Boost figure.
Best for: Home backup where something with a compressor — fridge, freezer, window AC — has to start reliably.
Where it falls short:
- 50 lb is heavy for its capacity
- Marketing leads with the 3400W X-Boost number, which understates it
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
