CyberPower CP1500AVRLCD3 Review: A 1500 VA Battery Backup With a Color LCD and Room for a Whole Desk
The CyberPower CP1500AVRLCD3 is a line-interactive 1500 VA / 900 W UPS that covers a desktop PC, monitors, a modem and a router with six battery outlets, six surge-only outlets and a color LCD that shows load and remaining runtime at a glance. Owners describe a painless setup and enough battery time to save work and shut down during short outages. The trade-off is the simulated sine wave on battery, which can upset active PFC power supplies, and an inverter that hums while it runs. For networking gear and an ordinary PC it is a well-equipped mid-range pick.
- Home office desks
- Modem and router backup
- Areas with frequent brownouts
- Home Assistant and NAS users
Pros
- 1500 VA / 900 W line-interactive design with Automatic Voltage Regulation
- 12 outlets: six with battery backup, six surge-only
- Color LCD showing load, battery level and estimated runtime
- USB-A and USB-C charging ports on the front
- HID USB port recognized by Windows, macOS, NAS units and Home Assistant via NUT
- User-replaceable battery and a three-year warranty that covers it
- Ethernet and coaxial surge protection
Cons
- Simulated sine wave on battery, not suited to active PFC power supplies
- Audible hum from the inverter while on battery
- Heavy sealed lead-acid batteries with a slow recharge

Who is the CyberPower CP1500AVRLCD3 for?
It suits anyone who wants a single tower beside the desk to protect a computer, its monitors and the network gear during brief outages and voltage dips. Its 900 W rating leaves ample headroom for a modem, a router and a couple of access points, which can run for a long time on battery, while a full desktop gets the few minutes it needs to shut down cleanly (12 minutes at half load and 3 minutes at full load, per CyberPower). Buyers in rural areas with unstable power lean on its Automatic Voltage Regulation, which corrects low voltage without draining the battery.
What buyers love
Setup is the most praised point: the UPS works out of the box, and Windows recognizes its HID compliant USB port immediately, showing a battery icon in the taskbar of a desktop PC. Owners also like how quiet it is on mains power, the large power button and the generous outlet count, which can feed a whole bedroom or home office. Several long-time CyberPower buyers point to the user-replaceable battery as the reason they bought another one: swapping the RB1290X2E cartridge costs far less than a new unit. The front USB-A and USB-C ports keep a phone charged through an overnight outage.
What to know before you buy
On battery the output is a simulated sine wave, not a pure one, so computers with active PFC power supplies may click, buzz or refuse to switch over; CyberPower's PFC Sinewave models are the alternative for those. The inverter also makes an audible transformer-like noise while it runs on battery. The two sealed lead-acid batteries need replacing every few years and take about 8 hours to recharge to 90%. There is no Wi-Fi, no network management port and no card slot, so remote alerts depend on a computer running PowerPanel Personal, and PowerPanel Cloud monitoring needs a paid plan. One owner in Canada also found the Connected Equipment Guarantee hard to use, since claims meant shipping the heavy unit to the US.
Does the CyberPower CP1500AVRLCD3 work with Home Assistant?
Yes, through Network UPS Tools. NUT reads this exact model with its usbhid-ups driver over the included USB cable, and the Home Assistant NUT integration then shows battery charge, load, runtime and input voltage, and can trigger automations when the power fails. The same USB HID connection lets Synology, QNAP, Unraid and TrueNAS shut themselves down before the battery runs out.
Is the CyberPower CP1500AVRLCD3 worth it?
For a mid-range price it bundles features that cheaper standby units skip: AVR, 1500 J of surge protection, coaxial and gigabit Ethernet line protection, a color LCD, USB-C charging, an energy-saving bypass mode and a three-year warranty that includes the batteries. Buyers rate it highly for exactly the job it is designed for, riding out short outages and shutting down safely. If your PC has an active PFC power supply or you want hours of runtime, look at a pure sine wave or LiFePO4 model instead.
Frequently asked questions
Is the CyberPower CP1500AVRLCD3 a pure sine wave UPS?
No. It outputs a sine wave while on utility power but a simulated sine wave on battery. That is fine for modems, routers and most PCs, but computers with active PFC power supplies are better served by a pure sine wave model.
How long does the CyberPower CP1500AVRLCD3 run on battery?
CyberPower rates it at 12 minutes at half load (450 W) and 3 minutes at full load (900 W). Light loads such as a modem and router last much longer, since runtime is not linear.
Can I replace the battery myself?
Yes. The battery compartment opens after loosening its screws, and the replacement cartridge is the CyberPower RB1290X2E (two 12 V / 9 Ah sealed lead-acid batteries). The UPS has to be switched off and unplugged for the swap.
Does it work with Home Assistant or a NAS?
Yes. Its HID compliant USB port is read by Network UPS Tools (usbhid-ups driver), which the Home Assistant NUT integration uses, and by Synology, QNAP, Unraid and TrueNAS for automatic shutdown.
How many outlets does it have?
Twelve NEMA 5-15R outlets: six with battery backup and surge protection, and six with surge protection only. It also has one USB-A and one USB-C charging port.
Can I monitor it from my phone?
Not directly. It has no Wi-Fi or network port; a computer running PowerPanel Personal can relay it to the PowerPanel Cloud app, which requires a paid plan.
