Introduction

Can you think of a way to charge all your mobile phones? Only one charging plug is needed to charge one mobile phone, but to charge three mobile phones at the same time, you need to find a new charging plug. Look carefully for the hidden information on the screen, maybe it is hidden next to the phone. If you can't find a new charging plug, Think carefully and try new methods, this is not a simple game, divergent thinking, a brainstorming!
