Original phone charger manufacturers tell you the misunderstanding of mobile phone charger use
1. The new battery requires a few full charges-a discharge cycle to activate
In fact, smart phones do not need this, because most of the smart phone batteries on the market are lithium-ion batteries. Its initialization process is completed during the manufacturing process, so it does not need to be activated during use.
2.Reduce the number of charging times to extend battery life
In fact, pay attention to the lithium battery "eat more", frequent shallow charge and discharge will help extend its life! Remember to "eat more", do not pull the phone for a long time, this will speed up the capacity loss rate of the battery.
Overcharging can cause the battery to explode
In the same theory, lithium batteries generally have safety protection circuits and various safety devices to ensure that when the battery automatically cuts off the circuit, excessive charging and discharging and short circuits occur. Unless there is a quality problem, the battery will not charge and explode for a long time.

According to foreign media reports, Apple just announced a notice to recall the product. The recalled product is not a MacBook with keyboard and display cable problems, but a wall plug adapter designed for the Hong Kong, Singapore and UK markets in China, which is our common triangular plug adapter. A reliable Bluetooth earphone wholesales china manufacturer.
Apple said that they have received six problem reports so far, and users have received electric shocks when using these old adapters. For this reason, the company is recalling these adapters so that they can be replaced immediately.
The “three-plug” wall socket adapters that need to be recalled use thick metal inserts. In contrast, the "three-plug" adapter on the US market has two thinner blades and a round grounding plug. It is reported that from 2003 to 2010, Apple equipped this adapter for Mac and some iOS devices.
Apple said the recall will not affect any of its USB power adapters.
Starting today, customers can replace the affected old adapter with a new one from the official Apple page. Returns and replacements are voluntary and not mandatory. However, for security reasons, the company asked users to stop using the old adapter.
It is understood that this is Apple's second recall of wall plug-in adapters in recent years. In early 2016, Apple recalled four different dual-tube adapters for similar failures. These adapters are available for continental Europe, Australia, New Zealand, Korea, Argentina and Brazil.

As smart devices occupy an increasingly important position in people's lives, with the gradual increase in functions, the problem of power consumption of devices is gradually exposed, and people are becoming more and more accustomed to carrying power adapters, that is, People often say the charger. What is the difference between this power adapter and the regulator?
It was found that the voltage of the power adapter was higher than the value he marked without load, and the regulator always had this value. So what is the difference between the two?
The difference between power adapter and voltage regulator
1. The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into an AC output type and a DC output type. Straightforward can be understood as a voltage converter, such as converting a 110-220 volt AC voltage into a fixed DC voltage.
2. The regulator is a device that stabilizes the output voltage. The regulator has a constant voltage, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, so that the position of the carbon brush of the regulator changes, and the output voltage is kept stable by automatically adjusting the turns ratio of the coil.
The power adapter is higher in voltage without load. If you pick up the load, it will find that its voltage will drop. This is because of its own limitation, just to provide a suitable voltage to the load. The main function of the regulator is to regulate the voltage. It will stabilize the voltage passing through it to a certain extent. If it exceeds or lowers this value, it will have an action. The power adapter does not have this effect. These two can be distinguished according to the use situation. If the load power supply requirements are not high, they can be used interchangeably. However, if the load requires a high power supply, even if the voltage of 1V does not change, then the regulator must be used. Otherwise, you should burn the power without burning the load.

Apple is taking new steps in the iOS system to prevent third-party replacement of iPhone batteries. Apple has activated a "sleep software lock" in iOS. When the iPhone uses a battery that is not installed by Apple itself, it will block the battery health and other functions in the settings. In other words, if the user or the non-Apple authorized third party to replace the battery task, the settings application will display a "service" information: can not verify whether the iPhone uses the original Apple battery. This battery has no health information.
The core technology is derived from the microcontroller of the battery itself, manufactured by Texas Instruments, which includes an authentication function that pops up a “service warning” if the authentication key provided by the battery does not match the iPhone. Apple and its partners are the only companies that can clear this information. This new software lock exists in both iOS 12 and iOS 13, and iPhone XR, iPhone XS and iPhone XS Max are all in control.
This is actually a soft tip message that won't cause the iPhone to be unusable, but will make it a detail feature that does. Regardless of whether the battery itself is original or not, this message will appear if it is not a battery that Apple or Apple authorized to repair the dealer.
Previously, Apple had been squandered by users because it did not allow third-party replacement batteries, but the fundamental reason why they would rather be killed is battery safety. The serious consequences of the Samsung Note7 spontaneous combustion incident have caused the battery to become an area of close attention to all mobile phone manufacturers, and no one dares to relax. Only your own battery, and your own approved installation channels can minimize the chance of accidents.

With the continuous development of the mobile phone industry, there are more mobile phone brands and more and more sales. There are also different quality data cables on the market, and various types of interface data cables are available to make you dazzled. Data cable wholesale factory teaches you how to buy high quality data cables
Preferred classification of known data cables:
From the interface to divide: COM interface and USB interface
1, COM interface is also called serial port, is connected behind the desktop computer, is currently being eliminated. The advantage is that the price is low, and the brush machine is supported (some mobile phones can only use the serial cable to brush the machine); the disadvantage is that the removal is extremely inconvenient, does not support the notebook computer, and the transmission speed is relatively slow.
2, USB interface is the current mainstream, the advantages are convenient and fast and stable, support all types of computers; the disadvantage is that the price of the IC is slightly higher, and some of the data cables do not support the brush function.
Today, Jianghan electronic data cable manufacturers explain how to buy high-quality data cables:
1, we first check the quality of the shape from the shape, first look at the surface of the injection interface, its quality can be seen in the molding compound, if the surface looks uneven and deformed, there is a crack surface is not bright and very dark The data cables are relatively poor. The surface of the good quality data line looks very beautiful. There is no print, the surface is shiny, and the quality is good.
2, look at the metal head is not rust, the socket is not deformed, there is no overflow in the interface, or it will damage your charger.
3, is the quality of the cable depends on the surface printing is not clear, the surface of the wire is rough and the grain sand is relatively poor wire, and then can also swing 180 ° up and down dozens of times to see if there is any break, usually A good quality data cable is so swayed dozens of times that there are no scars.
4, if conditions permit, you can also try to charge your mobile phone to see if you can charge, and then touch the cable during the charging process will not be hot and hot.

Speaking of mobile phone chargers, I believe that everyone will not be unfamiliar. The mobile phones we use every day need to be charged. Since we need to charge, we need our chargers. Many of the devices now require chargers, not just Mobile phones, such as computers and so on. Therefore, if the charger is used, it is mainly to see which aspect of the mobile phone charger wholesale factory is made. For the charger of the mobile phone, its internal electronic components use a lot of patches, and can also be used for automatic soldering, and Inspection and repair.
However, if it is a charger such as an electric car, there are many common internal components, and there are many large components inside. We can use machine plug-ins and manual installation. Because of the different battery products, it requires different methods to continue charging, so you must remember to charge according to the product instructions. The initial nickel-metal hydride battery was similar to activation. Because the battery will generate memory, if it is charged under the condition of not completely discharging, it is easy to make the battery excessively full, so that after a long time, the user will feel that the power of the mobile phone is quickly used. It’s over. However, most of the batteries used in current notebook computers, mobile phones, etc. are lithium-ion batteries. So its initialization is done at the time of manufacture. The advantage is that you don't need to activate it when you start using it.
