This is a poor ups, when I bought this zebronics ups then its working was normal I can’t 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 ups’s cost, to repair my pc,
so I didn’t 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
