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
Ampace Andes 1500 costs $3000 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 163% more energy (3840Wh vs 1462Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 5400W more surge headroom (9000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Ampace Andes 1500 is 95.5 lb lighter (36.8 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
Ampace Andes 1500
Backed by an Amperex/CATL cell pedigree, the Andes 1500 stands out on charge speed — 0-80% in well under an hour — and a light 36.8 lb for 1.5kWh.
Best for: Buyers who prize fast charging and low weight at 1.5kWh.
Where it falls short:
- Newer brand with a thinner track record
- Not expandable
