Anker SOLIX F3800 vs Allpowers R1500
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
Allpowers R1500 costs $3300 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 233% more energy (3840Wh vs 1152Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 6000W more surge headroom (9000W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Allpowers R1500 is 94.8 lb lighter (37.5 lb vs 132.3 lb).
- Anker SOLIX F3800 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
The Anker SOLIX F3800 is poor value on paper: 0.96 Wh per dollar versus 1.65 for the Allpowers R1500. 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
A well-priced 1.1kWh with a real 1,800W output and fast charging, a common budget pick for home backup starter kits.
Best for: First-time backup buyers who want 1,800W output cheap.
Where it falls short:
- 37.5 lb for 1.1kWh
- Not expandable
