EcoFlow DELTA 3 Plus vs Bluetti AC2A
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 $550 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 402% more energy (1024Wh vs 204Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 3000W more surge headroom (3600W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC2A is 20.8 lb lighter (7.9 lb vs 28.7 lb).
- EcoFlow DELTA 3 Plus is rated for 4,000 cycles vs 3,000 — 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 AC2A
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
