I bought Intex UPS for my desktop PC for saving it from sudden power loss or a voltage fluctuation .I’ve been using this UPS from around 4 years and it is said that the battery backup will last up to 2 years but for me it last up to 3 years and then I have to replace that battery for just rs 400 .
it give me battery backup of 25 to 30 minutes with a full charge. The negative point that I found was there was no customer service all over the India, you have to go to a large City for repairing it.
It is provided with the 3 sockets that can be used with a monitor, CPU and other accessories to work. there is also provision of USB slot but I don’t know why there is no hole inside it.
