Anker SOLIX C1000 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.
- Allpowers R1500 holds 9% more energy (1152Wh vs 1056Wh), 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.
- Anker SOLIX C1000 is 9.1 lb lighter (28.44 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 SOLIX C1000 in this matchup. It costs $300 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.
The default recommendation for most people. It clears the 1kWh bar, recharges in under an hour, and undercuts almost everything with comparable specs.
Best for: First-time buyers who want one unit for camping and short outages without overpaying.
Where it falls short:
- 2400W surge won't start a sump pump or well pump
- Only 1056Wh — a fridge-plus-devices outage tops out around a day
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
