Anker 555 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
These two cost the same, so the decision comes down to what you're powering.
- Allpowers R1500 holds 13% more energy (1152Wh vs 1024Wh), so it runs the same load proportionally longer.
- Allpowers R1500 has 1500W more surge headroom (3000W vs 1500W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 555 PowerHouse is 7.6 lb lighter (29.9 lb vs 37.5 lb).
- Allpowers R1500 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
We'd skip the Anker 555 PowerHouse in this matchup. It costs $0 more than the Allpowers R1500 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
A 1kWh unit whose 1,000W output and slow charging show its age — the newer, cheaper Anker C1000 beats it on nearly every axis.
Best for: Only worth it steeply discounted against the C1000.
Where it falls short:
- 1,500W surge is low
- 200W solar input and a slow 138-minute recharge
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
