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 $510 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 282% more energy (1024Wh vs 268Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 2400W more surge headroom (3600W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 18.6 lb lighter (10.1 lb vs 28.7 lb).
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 2,500 — meaningful if you cycle it daily.
EcoFlow DELTA 3 Plus
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.
Best for: Home-office setups where a desktop or NAS can't tolerate a power blip.
Where it falls short:
- $100 more for features many buyers never use
- Same 1024Wh as the cheaper DELTA 3
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
