The Anker SOLIX C1000 is the quietest 1 kWh power station we have tested — which makes it a specialist pick for renters who need overnight, in-bedroom backup. Here is our honest review.
Anker SOLIX C1000 — the bedroom-friendly backup
1056 Wh of LiFePO4, an 1800 W inverter (2400 W SurgePad), 6 AC outlets, a 58-minute full recharge, and expandability to 2112 Wh. The headline: the fan stays off below ~350 W, so it is near-silent for overnight use.
The short verdict
If your power station will live in or near a bedroom — for CPAP, a fan, a med fridge, or an aquarium — the C1000 is the one to get. For a pure desktop UPS, the Bluetti AC180’s faster transfer edges it.
What we like and what to watch for
What we like
- Genuinely the quietest 1 kWh unit — fan off below ~350 W
- Fast 58-minute full recharge
- 6 AC outlets and expandable to 2112 Wh
- Compact for the capacity

Real-world apartment use
In overnight tests the C1000 was the only 1 kWh unit that did not wake a light sleeper — the AC180 and DELTA 2 both spun their fans under similar loads. For a CPAP, a bedroom fan, or a quiet med fridge, that silence is the whole point.
Who should buy it — and who should skip
Buy it if: you need silent overnight backup in a bedroom (CPAP, fan, med fridge, aquarium).
Skip it if: you mainly want a desktop UPS (get the AC180) or the absolute most capacity per dollar.
Frequently asked questions
Is the Anker C1000 really that quiet?
Yes — its fan stays off below ~350 W draw, so for light overnight loads it is effectively silent, quieter than the AC180 or DELTA 2.
Can it run a CPAP all night?
Easily — a 40 W CPAP runs ~22 hours, and the silence makes it ideal bedside.
C1000 or Bluetti AC180?
C1000 for silence and bedroom use; AC180 for the fastest UPS transfer and a touch more capacity.
