Anker SOLIX C1000 vs Anker SOLIX F3800
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
Anker SOLIX C1000 costs $3000 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 264% more energy (3840Wh vs 1056Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 6600W more surge headroom (9000W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C1000 is 103.9 lb lighter (28.44 lb vs 132.3 lb).
- Anker SOLIX F3800 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The default recommendation for most people. It clears the 1kWh bar, recharges in under an hour, and undercuts almost everything with comparable specs.
Best for: First-time buyers who want one unit for camping and short outages without overpaying.
Where it falls short:
- 2400W surge won't start a sump pump or well pump
- Only 1056Wh — a fridge-plus-devices outage tops out around a day
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
