EcoFlow DELTA 2 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 $660 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 2 holds 282% more energy (1024Wh vs 268Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 2 has 1000W more surge headroom (2200W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 16.9 lb lighter (10.1 lb vs 27 lb).
- EcoFlow DELTA 2 is rated for 3,000 cycles vs 2,500 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
The value pick in the 1kWh class. Cheaper than the Anker C1000 with nearly identical capacity — but check the surge number before you buy.
Best for: Budget-conscious buyers running electronics and a fridge, with no motor-driven loads.
Where it falls short:
- X-Boost tops out at 2200W — the least surge headroom of any 1kWh unit we list
- 80-minute recharge is slower than Anker's 58
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
