The ordinary phone charger you are holding tightly in your hand may seem ordinary, but it hides a stunning scientific mystery - fast charging technology. When you gently press the power button, a strong current quickly rushes towards your phone, and within a few minutes, it can be fully revived. So, what scientific principles are hidden behind this? Let's unveil the mystery of fast charging technology together.

In traditional mobile phone charger manufacturing, plastic and metal are the main raw materials. Although these materials have good durability and conductivity, they are difficult to degrade and long-term retention in the environment can cause serious damage to the ecosystem. In addition, traditional chargers consume a large amount of energy during the production process and generate a large amount of exhaust gas, wastewater, and solid waste, exacerbating global climate change and environmental degradation.

That was an ordinary Wednesday, but for me, it was an exceptionally busy day. The morning sunshine seeped through the gaps in the curtains and sprinkled on my face, awakening the sleeping me.
