## Product: CyberPower CP1500AVRLCD UPS
**Brand:** CyberPower

The CyberPower CP900AVR UPS generally operates pretty quietly. From what we've gathered, it does make some noise, but it's usually minor and hardly noticeable unless the battery kicks in during a power outage or while it's charging. Some folks have mentioned a soft hum, but it's not too disruptive, so it should be fine for both home and office use where you might be worried about noise. 

The unit has a capacity of 900VA and 560W with 10 outlets—5 of them are battery-backed and surge-protected, while the other 5 are just surge-protected. It also has Automatic Voltage Regulation (AVR) to help keep voltage levels steady and protect your devices from power fluctuations, which is super helpful if you experience brownouts or voltage spikes.

In terms of performance during power outages, it’s generally reliable. Depending on the load, you might get up to 4 hours of runtime with a light 20W load, or around 17 minutes with a heavier 300W load. This should give you enough time to safely shut down essentials like [modems](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dmodems%26tag%3Dssw.ans.tx-1-20), [routers](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Drouters%26tag%3Dssw.ans.tx-1-20), [PCs](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DPCs%26tag%3Dssw.ans.tx-1-20), and [home entertainment systems](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dhome%2Bentertainment%2bsystems%26tag%3Dssw.ans.tx-1-20), preventing data loss and preserving settings during power interruptions.

That said, some people have mentioned a few downsides. There are concerns about the battery lifespan and the unit’s USB features for automatic shutdowns, especially with Mac systems. There have even been occasional reports of units failing sooner than expected, though experiences seem to vary. 

Despite these issues, many still find the CyberPower CP900AVR a worthwhile investment, particularly with its three-year warranty and solid connected equipment guarantee.

All in all, while the CyberPower CP900AVR does make a bit of noise, it usually isn’t a big deal for most users. If you’re looking for a budget-friendly and reliable way to safeguard your gear from power issues, it’s definitely worth considering. Just keep an eye on those potential USB compatibility and battery lifespan quirks.
