Anker SOLIX C1000 vs Allpowers R4000
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 SOLIX C1000 costs $1300 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 227% more energy (3456Wh vs 1056Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 3600W more surge headroom (6000W vs 2400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C1000 is 77.6 lb lighter (28.44 lb vs 106 lb).
- Allpowers R4000 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
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 large expandable unit that undercuts the EcoFlow Delta Pro 3 on price while matching its 4,000W output — the trade is a less established support network.
Best for: Whole-home backup buyers prioritising price per watt over brand.
Where it falls short:
- 106 lb
- Brand support and resale trail the big names
