Customer Ratings & Reviews

I’ve made it a point to keep my sensitive electronics on a UPS for the last twenty years. These modern UPS systems work a lot better than the old ones where I was lucky if I got 3 or 4 minutes to quickly shut everything down. The CyberPower LX1500GU3 is the most powerful battery back-up system that I have ever owned. With USB-C and USB-A charging ports, a hefty battery, a large on screen display, and a total of 10 outlets, the LX1500GU3 is a solid battery back-up. I wish that it had a higher joule rating. As a surge protector, it feels a bit lacking. But, if you’re wanting to keep your sensitive electronic devices working as long as possible in the event of a power outage, I can easily recommend this battery backup. Battery Life: During my tests, I let the UPS charge up and then loaded the battery to see how long I could run my PC and networking switch on a full charge. Using a PC with an 800-watt power supply and a 32-inch LCD monitor, I got about 45 minutes on a full charge on two tests. Not quite the duration I was hoping for, but, again, your mileage will obviously vary based on the load. There’s a battery life estimator built-in to the back-up, but it was all over the place and, ultimately, wasn’t very accurate. When I first started my tests, the back-up estimated that it could run for 78 minutes with my equipment. Instead, I was feeling good to get 45 minutes. Experience: This backup is huge. It’s the biggest and heaviest UPS that I have ever owned. I really like the ten outlets on the back of the unit. Having two set off outlets for larger bricks is a nice touch. My only complaint with that is, that if I used a brick in the set off port, the LAN ports were then blocked. I don’t have any reason to use the COAX ports, but I with the LAN ports and COAX ports were located somewhere else and the back was strictly for power, but that’s just me. One thing that bothered me about this unit was the surge protection. The surge protection only has an 890-joule rating. That’s a bit lower than I am used to with UPS and surge protectors. Ultimately, the LX1500GU3 may work perfectly well as a surge protector, but I would definitely prefer a higher joule rating. I prefer something with 1,100 to 1,500 joules, but again that’s just what I’m used to. Perhaps this will work fine for most surges, but I’m just not sure. Some things that I really liked about this UPS are the manual breaker, the customizable utility quality, sensitivity adjustments, and the low battery warnings. To engage with settings, you hold down the display button until you get into a menu option. Holding the button down for two to three seconds acts as a menu selection tool. I’m not describing it particularly well, but it works very well. From the menu, you can turn off the audible alarm. (Very useful when you are testing the battery life at 2:00AM with your pregnant wife in the neighboring room.) Plugging the USB accessory into a PC or laptop will work near instantly. Running on my Windows 10 PC, the battery shows up in the taskbar. I can then set my PC to automatically hibernate or shutdown when battery life reaches 5%. Conclusion: If you’re looking for a large battery back-up with plenty of customizable settings, the LX1500GU3 is a good option. I wish that it had more in the way of surge protection. The battery life was good, but battery estimator wasn’t terribly accurate. Still, this gives me more battery life than any other UPS I’ve owned. Based on battery life, built-in USB ports, and an easy to use interface, I'm recommending the CyberPower LX1500GU3. 4/5

I definitely recommend. Excellent backup battery supply. I use it for internet Wi-Fi box.

Purchased this to replace a 5 year old CyberPower UPS with the same rating. It was an upgraded model and provided a USB-C charging port. I may or may not use it. It was 60$ more expensive than the exact model I was replacing but I was nervous about possible aging out of the batteries in the older model units. For 50$ you can replace the batteries on these units so that should be a first option if you have time. No bells and whistles, just a battery UPS and a surge protector. I would like a different configuration of the plugs on the back. So far it is working fine. The batter kicks in as it should.

Easy to set up, easy to use. Weighs a good bit but keeps my devices running when power goes out

Good, but a little expensive. Easy to use. Very heavy.

I would be giving this 5 stars but I've yet to see it in operation (our power has been stable since I got it). Love the fact that I can power and protect my computer, 3 monitors, internet modem and wifi transmitter. Plus charge my phone, et al.

This is a great UPS lots of outlets that are spaced well and has USB on the front.

It’s easy to use, lil heavy but easy to fot anywhere.

I wanted to get a new surge protector so I upped for this version, so far it will keep my laptop and other stuff running for a few hours when the power goes out .

Good device a little to easy to use. Plug and play.

The battery backup has a quality build at a decent price. Has connections for both a direct connection to the current or connections with surge protectors. It is easy to install and to monitor. My wife has installed it on her computer and so far all has worked well.

Bought this to back up my wi-fi router and home security system. So far, so good. Does what it is supposed to. Has sufficient amount of outlets (10) 5 battery and 5 general, so you can plug lamps in and have light in the event of a black out. Would definitely recommend.

I've been using these for years on my TVs, gaming consoles, computers, and network devices. Best investment for your electronics needs.

I replaced my old UPS with this one. It can handle my server, router and NVR for my cameras well. No problems so far.

works great for when my power goes out. keeps my router powered up with no issues.

Works as advertised. I wanted APC but this done the same job well.

Has not bee put to the test yet. We have bad weather tomorrow so we may learn somethin then.

this UPS is perfect for medium size office server just remember to hook it up to the electricity for 8 hours before use

No true testing yet. Good for price. User friendly.

Very good and easy To install and very reliable great
