"01/07/2023= Today I tried to charge my car battery (initially it was showing 11.4 v)But as I connect it with 3 pin socket it sounds and fumes observed at exhaust vent of rehtrad battery charger.I bought the charger in October 2022 @ ₹ 1589 and went to use it for the very first time today but faced disappointment. Now I don't even know whom to contact for repairing.These chargers are not meant for regular use and has to be used only when required or in emergency. Therefore, it is a request to all of you to buy using your own discretion, the rest is your luck ahead.I had to charge the car battery outside last week as it didn't work.Edited on 16/07/2023= As product was under warranty so I contacted customer care (4-5 mails) and received the product today after about 10 days post mail and checked it by connecting it to power supply display is working but its real testing is pending as I didn't get such a chance."
