Has already saved my pc and ps5 10s of times!
Owned for less than 1 month, but due to the high demand on the texas power grid we have been having frequent power loss, this thing has handled it all amazingly. It smoothly rides short power outages and keeps my pc (with a 450 w psu) and ps5 running without any screen flickering or any noticeable change. And when long power outages happen it has provided enough time for me to safely turn off my pc, it has a clearly audible clicking noise when it turns on and an (optional) alarm to let you know when its running on battery power, so even if u aren't using your pc you should be aware when the ups is working and have enough time to shut down.This product has saved me a lot of headaches and protected my pc, would recommend!Update March 2024 - This ups is still doing great, whenever we have small brownouts it rides them like a champ and the battery can last for over 5 minutes with my pc and ps5 running, alarm still works and overall I have no complaints. This thing has been a lifesaver and saved me many headaches!

For the cost this product gives ALOT of value
This is connected to my micro atx gaming PC,7.1 home theater system,50 inch tv and a small crock pot. WIth all devices running full power the Powerpanel software tells me PSU usuage is:80-180watts in which i find really cool that the software gives you real time statistics,load,fluctuations in voltage coming in and out etc. The PSU itself is a good 10 pounds but it has a clean look to it. Overall it does its job the ONLY CON TO THIS PRODUCT is the alarm, its not super loud but it does get annoying quick so i disabled it, The software gives you live windows notifications when changes in power occur to your PSU, Enabling that and disabling the alarm is recommended if your close to your PSU but to each there own. The battery life is also another CON, even with my low power gaming rig and 50 inch tv i only get about 10-20min or more depending if i am playing a cpu/gpu intensive game. Now the whole point of any UPS is to let you turn off your electronics safely when a blackout etc occurs so to me this UPS is perfect for the price because im not spending an arm and a leg for protection while also getting alot of cool safety nets via the ups. There is better UPS out there if you have the money but this does everything i need it too with minor cons. The only NEGATIVES are you get an annoying alarm that does its job perfectly and you need to download the software in order to get the real time statistics information but it is worth downloading. (Company should be selling these with the software in cd)Overall a great UPS i highly recommend if you are tight on a budget and want VALUE for your buck.

Works perfect.
Where I'm living we have power blips, or flickers. These blips cycle the power through the whole house and shut off my ps5. The biggest annoyance is that literally right after the ps5 shuts down the power is already back on. This thing is very handy for that, ps5 stays on and it has many safety features and instructions on use. It has built in alarms and such that you can silence as well. Bonus, it is built like a tank, I don't exactly throw it around, but it could probably survive a decent drop, it's quite hefty.

it works
so far i like this thing just fine, I have a light and cordless telephone power supply and a radio hooked in. I do use a lift chain and an electric wheel chair that I might ad. I ordered this gismo after a 22 hour power failure. I am handicapped and live on the second floor and at least my neighbors and our apartment management folks looked out for those of us trapped upstairs. I would like to see a power supply for the elevator so we can get out in a similar swituation

Convenient small size
Similar performance to other ups but this small size makes it easy to mount on wall or other places where heavier ups won't fit

Garbage if you have a brown out. ONLY decent if you have total loss of power.
I have owned two of these for years and they are garbage. Unless you have a complete power outage they don’t work. If you have a brown out (power goes off and then immediately comes back on) they shut themselves off. You can’t do anything except MANUALLY turn them back on. However, you have to physically have access to the unit to do it. Isn’t the whole purpose of having these units is so things DON’T get shut down! I’ve opened a warranty for the battery and have even purchased new batteries and these units do it no matter what! Completely negates the purpose of purchasing them!
