Smart Universal Charger Box
People can invent a charger box. This box is like ultrasonic cleaner. When I used up a power bank, I just put it in the charger box. Then after few hours, the power bank is fully charged.
This is really interesting. May be the electric portable products in home can all implement some protocal to let them charge wirelessly. And they are all connected to cloud’s server. And there is a charger box. You just need to put bluetooth speakers, mobile phones, electric lamps, laptop to the box, smart watches to the big charger box. Then they can be charged up. It is like smart cashier machine in big supermarkets.
Just like wireless power bank can passed the energy to the iPhones, the charger box can pass energy from it to the electric products inside it. It is like Magsafe charger.
