Anker SOLIX F3800 vs Bluetti AC70
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 AC70 costs $3500 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 400% more energy (3840Wh vs 768Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 7000W more surge headroom (9000W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC70 is 110.3 lb lighter (22 lb vs 132.3 lb).
- Anker SOLIX F3800 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Anker SOLIX F3800
This is where portable power stops being portable and starts replacing a standby generator. The 240V split-phase output is the headline feature.
Best for: Whole-home backup where you need 240V loads and can't run a gas generator.
Where it falls short:
- 132 lb — this is a wheeled appliance, not something you carry
- $3,999 puts it against real standby generators
Bluetti AC70
768Wh with 1000W output at $499 — it does what the EcoFlow River 2 Pro does, with more output and more weight.
Best for: Campers who need to run a small fridge, not just charge devices.
Where it falls short:
- 22 lb — 5 lb heavier than the River 2 Pro
- Not expandable
