The two main camps, the Wireless Charging Alliance (A4WP) and PMA, have declared mutual compatibility, which means that future wireless charging devices based on these two standards will be able to be compatible with each other's phones, greatly expanding the scope of device adaptation. However, there are no details on how to achieve bidirectional compatibility between the two standards. Broadcom chief technology officer Henry-Samueli pointed out that the biggest obstacle to the adoption of wireless charging technology is the inconsistent standards.
Currently, wireless chargingThe electricity market is mainly competed by three major camps: A4WP, PMA and WPC (Qi standard). However, the decision by A4WP and PMA means that wireless charging devices based on their respective standards will be compatible with each other's phones, greatly broadening the scope of application of devices. Although there are no details on the compatibility of older products to the new standard, this development is certainly a positive sign.
The main difference between PLA and Qi, which are also electromagnetic induction, is that PLA uses existing accessories to make a fuss on the battery, so every mobile phone can achieve wireless charging through PLA, while QiIt's integrated into the phone as soon as it's on the screen.
Support wireless charging mobile phones are very many, in addition to the traditional Samsung, Apple, Huawei's three flagship, Xiaomi is the most active in wireless charging, wireless charging technology is also ahead of others a big cut.According to the mobile phone wireless charging method and implementation principle, it is generally classified into three categories, magnetic resonance, electromagnetic induction and radio waves. The most used is electromagnetic induction, compared with the other two wireless charging methods, electromagnetic induction technology is more mature, charging efficiency is higher than other ways. The second is his implementation structureid=' The difference between Wired and wireless charging '> The difference between wired and wireless charging
There are still gaps in the charging efficiency of wireless chargers, and there is still room for further improvement in technology. Long-term use of wireless chargers has no effect on mobile phone batteries, wireless charging will not reduce the performance of the battery faster. It is basically the same as wired charging, but the rate is lower, but the wireless charger still has a high energy conversion rate, which saves energy consumption more.
Different charging methods. First of all, the charging method of the two is not the same, the wired charging box must be connected with the cable and the charger, butPlug it into the charging port at the bottom of the box to charge it. The wireless charging box supports both wired charging and wireless charging, and can be charged on other wireless charging boards. Indicator positions are different.
The difference between wireless charging and wired charging is mainly: wireless charging of Apple wireless headphones wireless charging more than wired charging a wireless charging function, you need to equip yourself with wireless charger for charging; Apple wireless headphones Wireless charging and wired charging look slightly different.
Wired faster, although wireless charging is a very practical function, but only a part of the useHouseholds, wired charging faster, wireless charging more flexible, get rid of the bondage of the wire, pick up and put down, without alignment, you can charge quickly. Both sides have their advantages and disadvantages and can make up for each other.
Difference between the two: charging method. First of all, the mobile phone must be loaded into the charging protective shell, and then the protective cover is placed on the induction base, and then the induction base is connected to the power cord plug, and the power cord plug is plugged in. Wired charging is to plug the charging cable into the charging port of the phone.
1, the charging speed is slightly slower: compared with the wired charging bank, even if it has a fast charge, the charging speed of the wireless charging bank will be slightly slower, especially for devices with large capacity batteries, and the charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
2, Apple cable charge well. The advantage of magnetic absorption is that it can be adsorbed near, adsorbed can be charged, and the charger is automatically aligned with the charging coilPosition, solving the problem that traditional wireless charging requires manual alignment; But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
3, cable charging is good. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
4, the second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each charge on the go, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is more safe, more fast, its disadvantage is that the charge is relatively slow.
5, each has its own advantages: wireless charging is convenient, do not need to connect the phone to the charger, put on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
1, convenience: Wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.
2, however, wireless charging still has some limitations and inconveniences. This article will be on wirelessThe advantages and disadvantages of charging are analyzed to help users better understand this charging method. At present, the effective charging distance of wireless charging technology is still limited, and the phone needs to be placed on a device that supports charging. Wireless charging may lead to accelerated battery wear and shorten battery life.
3, convenience: non-contact, one-to-many charging compared with the general charger, reduce the trouble of plugging, but also avoid the interface is not applicable, poor contact and other phenomenon, the elderly can also be very convenient to use. (2) Versatility: a charger can be used for multiple loadsCharging, a family to buy a charger can meet the whole family to use.
4, first of all, the wireless charging efficiency is slightly low, the early equipment heating problem is serious, resulting in the back of the mobile phone hot, manufacturers have to make compromises on power control. (Balancing safety and efficiency was a challenge in the early days of wireless charging.) Second, wireless charging bases often require additional purchases and are expensive, sacrificing portability. (The trade-off between extra cost and convenience is a big consideration for users.
5, the efficiency is slightly lower: the general charger also has a transformer but wireless charging to transmit coil and receive coilBecause the transformer is limited in structure, the efficiency of energy transmission is theoretically lower than that of a general charger. Slow charging speed: Because most of the current receiving products such as mobile phones limit the input power, the charging speed is relatively slow.
6, wireless charger has advantages and disadvantages, the following are its advantages and disadvantages: Advantages: The advantage of wireless charger is that we can use the mobile phone at the same time to charge, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable.
