Anker SOLIX F3800 vs Bluetti Apex 300
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 Apex 300 costs $2400 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 39% more energy (3840Wh vs 2764Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 1320W more surge headroom (9000W vs 7680W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti Apex 300 is 52.9 lb lighter (79.4 lb vs 132.3 lb).
- Bluetti Apex 300 is rated for 6,000 cycles vs 4,000 — meaningful if you cycle it daily.
The Anker SOLIX F3800 is poor value on paper: 0.96 Wh per dollar versus 1.73 for the Bluetti Apex 300. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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
6000 cycles at 2764Wh — the best long-term cost-per-kWh in this list if you cycle daily. Bluetti's answer to the Elite 200 V2 at scale.
Best for: Off-grid solar setups where daily cycling makes lifespan the dominant cost.
Where it falls short:
- 79.4 lb
- Newer product with limited long-term field data
