Anker SOLIX C800 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
Anker SOLIX C800 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R1500 holds 50% more energy (1152Wh vs 768Wh), so it runs the same load proportionally longer.
- Allpowers R1500 has 1400W more surge headroom (3000W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C800 is 12.6 lb lighter (24.9 lb vs 37.5 lb).
- Allpowers R1500 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
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 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
