Intex UPS protector 725 cost 1400 rupees. The back time it gives is of ten to fifteen minutes. Earlier when I purchased this product the company was giving two years of warranty but now warranty period has been lower down to one year. My be the company has lost confidence from their own product.
If it stops getting power supply it produced alarm sounding every ten seconds and if its get overload the alarm sound every 0.5 seconds.
I bought this product one and a half year back and now before its warranty periods it has stopped working. The place from where I purchased it has clearly said no to repair it.
It is a light product with low quality and can stop working any time. You cannot trust this product.
