ZUS smart car charger stopped working just after a day of use


I recently bought ZUS smart car charger, used it for a day. And now all of sudden it stopped working, i’m unable to see the lights turning on. It’s off from last 13hours. I kept it connected to my car all the time. I even tried removing from car charging port and connected it back. Nothing seems to be working. Is there any hardware issue? What might be reason. It’s not turning on even after i start my car.
