Ningxia's action also attracted the attention of the three people.

"Let me show you the universal charger."

As he said that, Ningxia directly took out the battery of his mobile phone.

At this time, the three of them also stood up and surrounded them.

Miao Yufeng saw Ningxia removing the battery and looked puzzled: "Xia Xia, didn't you say you invented a charger? Why are you removing the battery?"

Bao Xuexin, who knew nothing at this time, was even more confused by Ningxia's actions.

What charger?

"Xia Xia, this thing you invented..."

Cheng Hua didn't know how to describe it at this moment.

Looking at the flashing red lights, Cheng Hua seemed to understand something at this time, and also knew why Ningxia called this thing a universal charger.

"This thing can charge...all cell phone batteries?"

Ningxia straightened up and nodded, smiling without saying anything, and decided to wait until the battery was fully charged before talking about anything else.

It was not until the dishes were served that Ningxia took out the battery and put it into the mobile phone in front of the three people.

He handed the phone, which now had 40% battery, to Cheng Hua.

Bao Xuexin looked at the phone that was passed to him and looked at Ningxia.

Dai Dai asked, "Is it so magical?"

If this thing goes into mass production, there will be no need to worry about your phone running out of battery.

Cheng Hua kept scratching his forehead at this time. He never expected that Ningxia would design this thing.

I really underestimated Ningxia.

It was also the first time that he realized that Ningxia's genius far exceeded his imagination.

If this thing is really produced, it can really be said to bring in millions or even tens of millions of dollars a day.

Nowadays, almost everyone has a mobile phone, and anyone who has one is troubled by the poor battery life.
