Hii I am shobha rawat . I need to tell you about my v guard inverter . Somebody suggest me to buy this inverter but it is giving us alot of problem probably after charging normally for 3 hour it get heated too much . I have given complain to the customer service also but they didnt respond towards my complain fastly after a week they send an engineer but he was also not able to find the exact problem and started unquestioning us that did we have done something which is not suitable for this air cooler . It was so embarrassing that time I have decided to switch to some other air cooler because its repairing cost me too much
