This is a poor ups, when I bought this zebronics ups then its working was normal I cant say not too much good but overall it was ok, but after few months its performance go down, my pc also get damaged due to its miss work, and I have to pay more than this upss cost, to repair my pc,
so I didnt recommend you to buy this , if you want to be safe and lang lasting backup than you should try another one company ups, simply by looking on reviews on mouthshut or from any other source but you should buy only a geniun product
