Bluetti EB3A vs EcoFlow DELTA 1300
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 $760 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 370% more energy (1260Wh vs 268Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 2100W more surge headroom (3300W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 20.8 lb lighter (10.1 lb vs 30.9 lb).
- Bluetti EB3A uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Bluetti EB3A is rated for 2,500 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA 1300. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
