EcoFlow DELTA 2 Max vs Bluetti EB3A
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 EB3A costs $1360 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 2 Max holds 664% more energy (2048Wh vs 268Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 2 Max has 3600W more surge headroom (4800W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 39.9 lb lighter (10.1 lb vs 50 lb).
- EcoFlow DELTA 2 Max is rated for 3,000 cycles vs 2,500 — meaningful if you cycle it daily.
EcoFlow DELTA 2 Max
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
Bluetti EB3A
The budget veteran. 268Wh at $239 with a 30-minute recharge — still one of the fastest-charging small units you can buy.
Best for: Budget campers who value fast top-ups between trips.
Where it falls short:
- 2500 cycles is the lowest here
- 268Wh empties fast under real load
