Anker SOLIX C800 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 C800 costs $1700 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 350% more energy (3456Wh vs 768Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 4400W more surge headroom (6000W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C800 is 81.1 lb lighter (24.9 lb vs 106 lb).
- Allpowers R4000 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
The C1000's smaller sibling. Same fast-charging DNA at a lower price, but the 768Wh capacity puts it firmly in weekend-trip territory.
Best for: Campers and van-lifers powering electronics, lights and a mini fridge — not home backup.
Where it falls short:
- 300W solar input is low — slow to top off off-grid
- 1600W surge rules out most motor-driven appliances
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
