In the digital age, more and more digital products are crowded around people. Mobile phones, tablets, handheld game consoles... These low-voltage products require a power adapter that is larger or smaller, without exception. And they are getting more and more cumbersome and occupying more and more living space.
Not the same function
The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances, and generally consists of a casing, a power transformer, and a rectifier circuit. Don't underestimate this thing, its family is extremely large and different in form. Black heavy box power is an adapter integrated in the plug; most of the notebooks have a rectangular parallelepiped on the power cord; desktops, in fact, there are inside the chassis; Apple products, seemingly much bigger than ordinary plugs The white square is also a type of power adapter.
Can the standard be unified?
The functions on the power adapter are the same, converting the civilian AC into the voltage and current required by the product. Because the products are different, they require different voltages and currents. Can the standard of the adapter be unified so that the same adapter can supply and charge many products? Different electronic products require different voltages and currents, especially those with large difference in volume function.
Big event
Since the unified standard is more difficult, can you make the power adapter smaller? For example, the power supply size of all kinds of mobile phones is more acceptable. In the field of notebooks, the power of Mac (Apple laptop) is much smaller than that of PC (computer).
Therefore, the power adapter's large and complicated problems, so far there is no solution. It seems that it is easier to design more sockets for the room. Still, future technological changes will change the status quo. Fortunately, the power adapter has a high recycling rate and does not cause too much pollution to the environment.
