Anker SOLIX C800 vs Bluetti Apex 300
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 $1000 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti Apex 300 holds 260% more energy (2764Wh vs 768Wh), so it runs the same load proportionally longer.
- Bluetti Apex 300 has 6080W more surge headroom (7680W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C800 is 54.5 lb lighter (24.9 lb vs 79.4 lb).
- Bluetti Apex 300 is rated for 6,000 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 Apex 300
6000 cycles at 2764Wh — the best long-term cost-per-kWh in this list if you cycle daily. Bluetti's answer to the Elite 200 V2 at scale.
Best for: Off-grid solar setups where daily cycling makes lifespan the dominant cost.
Where it falls short:
- 79.4 lb
- Newer product with limited long-term field data
