During power cut it creats a very high frequency sound which buzzes in ear. But that's not intolerable now. However I am using it for two months. I am using a thin client and it gave me 1 hour back up. Astonishing performence.

Good Product.
Using for my WIFI backup & POE Antenna.
Works for 3-4 hrs easily with no beep noise.
Uninterrupted power and internet.
Good for WFH

I use it for router and so far no issue

Using it to back up my router alone, since it supports micropower. Getting approximately 2Hr backups for my router, my router is a 12W device. Anticipated a bit more backup especially when only the router is connected... Easy to set up, ensure charging the UPS for around 8Hrs before using.

Edit after using for 4 months:
Faced a problem with backup, it dropped to a mere few minutes, raised the issue with Flipkart and Zebronics team, they had sent the service person to the doorstep and got the...

Finally I got non defective product after doing 2 time replacement..
Ups is good for small backup
Back time is 15-20min for desktop

Very nice backup using this from a month...never let me down

it saves my life my ps4 pro runs fine with this without even a single blink on apex legends... but like high cod mw or horzion wich consume higher rate of graphics. then i wont handel it.. and gta v runs fine.. most importan thing u can close every application and just download a game it give a power upto 10mins and in rest mode i hve run these hours..

When I purchased.. it's working and give backup 15-20m.. Now after 5-6month atleast 5minuts backup not giving

Good

Perfect for WiFi router n modem only ups that supports micro load, very happy with this model.
