Anker SOLIX C800 vs Bluetti AC500
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 $1400 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 300% more energy (3072Wh vs 768Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 8400W more surge headroom (10000W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C800 is 41.2 lb lighter (24.9 lb vs 66.1 lb).
- Bluetti AC500 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
Anker SOLIX C800
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
Bluetti AC500
A modular home-backup system, not a portable unit — the AC500 has no internal battery at all until you add B300K packs.
Best for: Serious home-backup builds where you're designing a system, not buying an appliance.
Where it falls short:
- Requires separate battery packs to function at all — budget accordingly
- Total system cost climbs fast
