It claims 40 minutes battery power, managed to get one hour backup for my qnap 4 bay NAS and a network rack (gateway, 24port 400w poe switch, ONT and 4 access points).

after 3 month beep is came and Stopped Working-Battery Issuei purchased same model 2 Device and Same Problem-don't Purchase This Brand

This product offers amazing quality hardware but its software is initially configured to continue making a very annoying loud beep every second while on AC mode, and then it automatically shuts down in 10 minutes even if the battery is still full. Good news is that you can change this from the settings, but bad news is that in order to access the settings, you have to install and configure that poorly documented stone again software that comes with the product ( it's name it UPSilon 2000 ) and you have to activate it using the license code that comes with the product and the connection the UPS through USB to the windows PC on which you installed and activated the software, and make sure to change the "Communication Type" to Mega(USB) in the settings of the software or else it wouldn't connect. Once connected you can customise all sorts of availabile settings for the UPS

Good, I’m using it for my NAS and it’s all going great so farWhen I shut off the power (for testing) it keeps on beeping so I like that feature and you can also connect it with the included USB cable so that when the backup battery reaches a certain percentage or after some time then it sends a signal for your PC or NAS to shut down gracefully

I have a 19" rack with 3x Dell R230 servers that need UPS protection. I purchased the Tecnoware 2400 as a replacement for an APC unit that developed a hardware fault. First thing to note is that the Tecnoware will not mount on the APC rails. However, after installing a 1U short shelf, the UPS slid into place and seems securely mounted (it is a little lighter than the APC unit).The UPS comes with a USB cable that you can connect to one of the servers. The Tecnoware website has documentation and software for the UPS. The software allows you to run a script to shut down all the servers when the battery capacity reaches a certain limit. easy to configure and it works (on WS2019).It has only been 1 week, but going by first impressions I would be happy to purchase another Tecnoware UPS.

Unable take charge sometimes and backup got 5minuties only

Broke after a year and a half. I dont know why

Very useful and functional UPS for desktop PC. It is working fine with my Dell optiplex 7020.
