How to Change the Damaged Screen of Khons Gen-2 Portable EV Charger?

"What should I do if my portable EV Charger screen which I bought from Chengdu Khons Technology Co., Ltd is broken or just not working?" Some of our customers asked.


As very sensitive components, although we use foam, bubble paper, and cartons to package our products, it is inevitable that some damage will occur during the packaging and transportation.


How can I confirm that only my charger's screen didn't work?


Just simple steps then you will know whether your charger's screen is broken or not:

1. First, connect the charger to the power outlet and confirm that the screen is not working

2. Connect the charger to your vehicle and confirm that the charging is normal, but the screen is still turning off.

After above two steps, we can confirm that the EV charger's system is normal except the screen is not working.
