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 C2000 costs $1000 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 69% more energy (3456Wh vs 2048Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 2400W more surge headroom (6000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C2000 is 57.5 lb lighter (48.5 lb vs 106 lb).
- Allpowers R4000 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
Anker SOLIX C2000
2048Wh at $1299 with fast 70-minute charging. Sits between the C1000 and the F-series without a standout spec of its own.
Best for: Anker loyalists who want 2kWh and fast charging in one box.
Where it falls short:
- 3600W surge trails the DELTA 3 Max's 4800W at a higher price
- 3000 cycles vs 4000 from newer rivals
Allpowers R4000
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
