Bluetti EB3A vs Anker 757 PowerHouse
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.
- Anker 757 PowerHouse holds 359% more energy (1229Wh vs 268Wh), so it runs the same load proportionally longer.
- Anker 757 PowerHouse has 1200W more surge headroom (2400W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 33.8 lb lighter (10.1 lb vs 43.9 lb).
- Anker 757 PowerHouse 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 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
Anker's older flagship, now a discount play. Solid and durable, but heavy for its capacity and outclassed on charge speed by the newer C-series.
Best for: Buyers who find it discounted below the newer Anker C1000.
Where it falls short:
- 43.9 lb for 1.2kWh is heavy
- 300W solar input is low
- Outclassed by the newer C1000
