I prefer working on my desktop instead of laptop. As we all know that UPS is one of the crucial parts that the system should be connected with. But before I purchase this iBall Nirantar UPS-621V Sine, I had been struggling with a faulty UPS that didn’t provide the power even more than 5 minutes and I had to connect my system with the inverter as soon as there is power cut.
Now after buying this new UPS I am happy working at my system since it provides backup power as long as possible. This is one of the most powerful brands that manufacture such powerful UPS. The average backup time is around 1 to 2 hours depending on the condition that if it is fully charged. I am using it for the last 1 year and I didn’t face any problem with it.
