Anker 757 PowerHouse 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 $300 less. Whether that gap is worth closing depends on what you need to run.
- Anker 757 PowerHouse holds 7% more energy (1229Wh vs 1152Wh), so it runs the same load proportionally longer.
- Allpowers R1500 has 600W more surge headroom (3000W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Allpowers R1500 is 6.4 lb lighter (37.5 lb vs 43.9 lb).
- Allpowers R1500 is rated for 3,500 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.
Anker's older flagship, now a discount play. Solid and durable, but heavy for its capacity and outclassed on charge speed by the newer C-series.
Best for: Buyers who find it discounted below the newer Anker C1000.
Where it falls short:
- 43.9 lb for 1.2kWh is heavy
- 300W solar input is low
- Outclassed by the newer C1000
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
