Is it cutting corners or technological advancement? Why are those bulky power adapters gone?

When it comes to laptop chargers, which of the following will appear in your head?

Under normal circumstances, we conventionally call the left one “power adapter”, and you need to connect another power cord to use, and the right one will be directly called “charger”.

Power adapters may already be the product of the old last generation for many light laptop users, and this power adapter was equipped with when laptops first became popular ten years ago. And now thin and light books like MacBook and Matebook have begun to use a simple charger.

Of course, there will be some gamers who come out to refute: Who said that the power adapter is obsolete? I’m still using these big bricks!

Why is the same notebook so much worse in charging form? Is there any difference between a charging head and a power adapter?

I believe many people will have this question.

In fact, in essence, both forms are essentially both

AC-DC isolated switching power supply, but the size of the volume will be seriously limited by the power: most portable notebooks do not have a discrete graphics card, the power required is also very low, and the internal components and heat dissipation structure of the charger can be very small.

But large game books of eight, ninety or even hundreds of watts at every turn, if they are also made into charging heads according to traditional technology, will get a large and heavy “moving brick”, and they know that they will fall off immediately if they are plugged into the wall. Therefore, notebooks with too high power will adopt the structure of power cord + power adapter.

With the development of technology, the power of the general notebook is getting smaller and smaller, Apple’s MacBook Air even has an ultra-small power design of 29W, and the laptop charger can be about the same size as the iPad charger.

So now, our more common portable books have long been replaced with portable chargers, but less common game books or some notebooks that are not mainly portable are still using “big” chargers.

Does this mean that non-portable does not have a portable need?

For example, many college students can only choose to buy a powerful game book based on the professional needs of university courses, or can play large games in the dormitory, but there is still a need to bring a notebook to class, or take a notebook to the library. At this time, it is necessary to carry a huge power adapter, which can be said to be “negative portability”.

Even from an aesthetic point of view, large and heavy adapters are very “unsightly”.

To solve this problem, it is necessary to sacrifice the big killer of “gallium nitride”.

Last year, Alibaba DAMO Academy released the “Top Ten Technology Trends of 2021”, and gallium nitride is at the top of the list. The charger has the blessing of gallium nitride technology, which perfectly realizes both high power and small size.

Recently, the well-known digital brand Greenlink launched a high-performance 100W four-port gallium nitride.

The small size that can be easily held in the palm of your hand, weighing only 215g, 3 USB-C ports and 1 USB-A port are fully configured, whether you go out or use it daily, one charging head can solve various charging problems.

The C1 port supports a maximum output of 100W, and many high-power notebooks can completely abandon the original large and heavy charging head.

It also supports four-port synchronous output and mainstream fast charging protocols such as PD/QC/SCP/FCP/AFC. The foldable pin design also greatly improves portability.

Even if the notebook being used is not a “big man” configured with power adaptation, high-power multi-port gallium nitride is very practical. Imagine the following scenario: when traveling, you no longer need to prepare charging heads for various devices, but you can go out with gallium nitride; No more worrying about having no place on the socket row, or having to use the plug row because of the tight insertion position… Just one gallium nitride charger can beat one against four.

Of course, the most important thing for chargers is safety. Greenlink 100W gallium nitride has a variety of built-in protection mechanisms, and there is no need to have the trouble of “small size, will the performance shrink”.

If you’re struggling with a non-portable power adapter, or don’t want to use a variety of charging heads, try this “all-in-one” GaN charger.
