HI Friends, i will share information about the Zebronics UPS U725 Inverter. I purchased this inverter in the Price is Rs 1700/- the performance of the inverter is very poor. this capacity of inverter is 600 VA with a input voltage range of 140-300 V+10%AC.this UPS battery type is 12 V/7 Ah*1. it takes approximately 6 hours to get full charged. this is directly switched off and the power off.the UPS would work for 5-10 minutes automatic power off and on. it is software malfunctioning . this is gets automatic heated just use one hour.this is not use friendly.this UPS style and design also very worst, the value of money is waste for buying this UPS. this company does not support and service this UPS also very poor.sometimes it gives strong back up and sometimes its charge for whole day but its automatically down in 30 minutes. I recommended for peoples please don’t buy this UPS. Thank you very much.
