Anker SOLIX F3800 vs Bluetti EB3A
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 $3760 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 1333% more energy (3840Wh vs 268Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 7800W more surge headroom (9000W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 122.2 lb lighter (10.1 lb vs 132.3 lb).
- Anker SOLIX F3800 is rated for 4,000 cycles vs 2,500 — 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 EB3A
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
