Anker SOLIX F2600 vs Anker 535 PowerHouse
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 535 PowerHouse costs $1070 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F2600 holds 400% more energy (2560Wh vs 512Wh), so it runs the same load proportionally longer.
- Anker SOLIX F2600 has 2050W more surge headroom (2800W vs 750W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 535 PowerHouse is 45.0 lb lighter (16.7 lb vs 61.7 lb).
- Anker SOLIX F2600 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
An odd spec sheet: 2560Wh of capacity but only 2800W surge — the lowest surge-to-capacity ratio here. Capacity without starting power.
Best for: Long-duration backup of steady loads (lights, electronics, CPAP) rather than motor-driven appliances.
Where it falls short:
- 2800W surge is barely above its 2400W continuous — it will struggle with pumps
- 61.7 lb
A durable half-kWh unit for devices and light loads. Dependable, but the low output and slow charging make it a device-first companion.
Best for: Campers charging phones, laptops and lights, not appliances.
Where it falls short:
- 500W output is device-scale
- 120W solar input, slow recharge
