I bought this UPS 2 months ago for my computer system. UPS didn’t work properly after 15 days. But after 1 month now this UPS is not giving back up for more than 10 seconds and when power off computer also goes off. It does not provide uninterrupted supply to my computer. I have attached only one device to it and its has failed quite miserably. For some days it was working fine but then one day suddenly a continuous long beep started sounding. Now I don’t even connect any plugs and start the UPS the faulty beep starts playing. Totally waste of money.
