Bluetti AC2A 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 AC2A costs $800 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 518% more energy (1260Wh vs 204Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 2700W more surge headroom (3300W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC2A is 23.0 lb lighter (7.9 lb vs 30.9 lb).
- Bluetti AC2A uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Bluetti AC2A is rated for 3,000 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.
One of the cheapest LiFePO4 stations on the market. 204Wh is tiny, but a 200W solar input that outpaces the capacity makes it a surprisingly capable little off-grid trickle unit.
Best for: Ultralight campers who recharge from a panel daily.
Where it falls short:
- 204Wh is genuinely small
- 300W output is device-only
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
