"Good" and "bad"
First of all, no matter in work or life, the development of "wireless" is the general trend, it represents the future direction.
Because compared with wired, wireless can give a greater degree of equipment freedom and reduce restrictions in space. When it becomes more mature, it is a double improvement of convenience and efficiency.
The premise is more mature. The development of wireless obviously has a long way to go.
Advantages:
Remove cable restrictions and use as required
No frequent contact with the power supply is required to reduce the risk of electric shock
Put into use in public areas, convenient for people and business
Match with personalized accessories for unexpected results
A typical example is Starbucks, one of the PMA alliance, which plans to set up wireless charging panels in its stores to provide customers with the convenience of charging.
Starbucks is part of a broader blueprint for wireless charging in public areas.
Speaking of accessories, the market for wireless charging accessories is even more crowded with the arrival of Apple's magnetic magnet feature MagSafe.
You can see a lot of unique products coming out, not just wireless power banks.
This has virtually boosted the demand of multiple industries, and for consumers, it has also added more user experience, we still don't know -
In the future, wireless will react with designs and materials.
At least I'm looking forward to it.
The technology of wireless charging has been around for a long time, and it has only made significant progress in the last few years. Admittedly, it still has many limitations.
Disadvantages:
Theoretically lower charging efficiency than wired
The heat is more pronounced and the battery drains faster
There are strict limits on the charging distance
The main concern for many people should be that wireless charging is so inefficient that the time it takes to charge a phone is almost back to the wired level of a few years ago.
First of all, due to the limitation of charging principle and the difficulty of unifying the standard, the technological upgrading process of wireless charging in the past few years is quite slow, which in fact began to have a leap forward breakthrough around 2020
Huawei, Xiaomi, OnePlus and other domestic mobile phone manufacturers have updated the power limit of wireless charging, which has reached 50W fast charging for large commercial areas.
Other brands may follow in the near future. The problem of power is solved, and with it comes the problem of heating.
However, we are not without solutions to this problem. For high-power wireless chargers, adding cooling devices (such as fans) can solve the problem of heat accumulation to a certain extent.
However, we should know that unlike wired charging, which mainly increases the temperature at the charging port, the principle of wireless charging will cause the temperature to rise directly at the battery end. However, the battery is very sensitive to temperature, and the higher temperature at the root has a more obvious influence on its life - compared with wired charging.
Q & A
Q: Wireless charging is slow and hot?
A: We have already answered this question above. There are high-power wireless charging products on the market, and for conservative enterprises represented by Apple, the wireless charging products have reached the level of about 15W, which is not very slow. Of course, it is much lower than the wired ones.
The problem of heating does exist, so there are corresponding internal cooling measures, such as the maximum power duration is not the whole process, and external cooling devices (commonly seen in vertical wireless chargers).
In addition, our most common standard, Qi, aims to achieve interoperability between various charging pads and portable devices, and brands like Apple and Samsung are members of the consortium.
The Qi standard clearly specifies the temperature rise requirements, so the safety of products under this certification is also guaranteed.
Q: Does wireless charging emit radiation? Does it cause cancer?
A: Wireless charging of mobile phones will produce a certain amount of radiation, but under the premise of quality assurance and correct use, this radiation is almost no harm to human body, let alone carcinogenic.
On the one hand, in wireless charging, the magnetic field is closed, and the radiation to the outside world is small;
On the other hand, as long as it is through the national 3C certification of the product, will go through strict inspection, its radiation must also meet certain standards, will not be harmful to the human body.
Q: Does the radiation from various electronics add up?
A: All electronic products have radiation, but as long as they meet the national 3C certification standard, they will not cause harm to human body.
In the case of radiation superposition, you have to meet very strict conditions.
In everyday life, "1+1=2" or "1+1>2" is rare, and the radiation from various electronic products interferes with each other, but does not add to each other, and in many cases even cances each other out.
For example, if you have a lot of people throwing stones at a lake at the same time, each pebble will form a wave, but these waves will not add up to a big wave, and radiation will not add up.
The attitude of many users is that wireless charging is useless. The low efficiency and the fact that the horizontal charging dock does not allow the phone to be charged at the same time will undoubtedly cause some users problems.
We say that wireless charging does still have many limitations at this stage, but its existence is not in conflict with wired.
Because what wireless charging can bring is a kind of "mindless charging" lifestyle.
It is primarily positioned to exist in the work life of the fragmented time of charging. When you leave it at work, the user continues to work, and the phone silently accumulates power.
It is an unconscious experience brought about by wireless charging that can keep the battery level at combat readiness without deliberately pursuing charging speed.
What's more, various forms, including magnetic absorption, once solved the problem of browsing information efficiency to a certain extent.
Get rid of the cable, don't bother, always ready, always available. As the power and charging distance increase in the future, we believe this will be an increasingly comfortable experience.
