Now I am going to share my experience of this iball nirantar UPS-621v . iball is veery famous company in the word and this company made UPS, CPU etc. I brought this product from a market at approx 1300-1400 Rs
This inverter gives you a good battery backup and gives you a time to switch off your computer. It gives you time between 10-15 minutes. Packing is good and anyone can ease handle the box.It occupies a little space near your computer.Looks too good at seeing. Talk about the service support of iball, the service is good enough.
Ups is good and experience is good with not more thing to share for this Ups.Nice
Thank you
