How about Zhida Technology? Has anyone ever used Zhida Guardian?

Zhida Technology is the earliest and largest provider of home and community charging products and services in China, with a wide range of business, serving more than 350 cities and signing more than 60 automobile brands, such as BYD, Great Wall and Dongfeng. Guardian is one of their charging pile products. I used it. Insert the charging head into the slow charging and start charging immediately. APP version is more convenient than credit card version. If you haven't bought it yet, it is recommended to buy the app directly. After all, you can control the charging time. It will be more cost-effective to charge the electricity price at midnight when it is cheap. Baidu may wish to know about it.
