Mobile phone charger misunderstanding

January 13, 2020 by keikeilaiy  

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.

What do I need to pay attention to when ordering USB data cables? First of all, it is necessary to meet two conditions, stable data signal transmission capacity and high efficiency of current transmission. The following USB data cable wholesale manufacturers will take you to understand in detail.

 

What do I need to pay attention to when ordering usb data cables?

 

1. Stable ability to transmit data signals

 

At present, under the influence of various interference factors in the surrounding environment, the interference signals existing outside may enter the inner conductor of the data line and affect the corresponding data transmission effect. Therefore, in the current customization of high-quality and reliable USB data cables, it is even more necessary to meet the stability of its data transmission functions. From what brand analysis of the current USB data cable customization, it can be found that a high-quality USB data cable customization mechanism can implement a comprehensive design of multiple shielding layers based on this good design effect, and achieve comprehensive control through this level of design to avoid external signals. Interference factors to ensure the efficiency of data transmission and the stability of signal communication.

 

2. High efficiency of current transmission

  
In daily applications, the data cable also needs to bear certain current transmission and charging functions, while the mobile phone’s continuously increasing requirements for high-efficiency charging capabilities and flash charging functions, but also requires high-quality USB data cables to provide stable current transmission. At present, the high-quality usb data cable customization mechanism uses constant current adjustment and continuous testing of its current production scheme, so that its usb data cable customization products have more efficient current flow capabilities.

Apple recalled plug adapters in Hong Kong, China

December 6, 2019 by keikeilaiy  

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.

November 8, 2019 by keikeilaiy  

Professional phone headset wholesale suppliers tell you how to increase phone headset life

1. Do not wear headphones when you are sleeping. When you are sleeping, people will often move. With headphones will be wrapped around the neck and twisted together with the two headphones, the headphones will be crushed.

2. Wipe the sweat on the headphone cable after using the headphones. Something secreted by these humans, containing fat or something, is at the bend of the ear. After a long time, the wire rod will age, eventually leading to cracks and cracks.

3. It is best not to smoke when using headphones. Accidentally, the earphone shell and headphone cord will be burned. In addition, soot will enter the earphone shell and stick to the shock film, and the sound quality will become worse after a long time.

4. Be sure to turn down the volume before use. If the volume of your output device is too loud, not only will your ears be shaken, but lighter membranes will wrinkle. Seriously burned the voice coil of the phone headset.

5. Keep headphones away from strong magnets. The magnetic properties of the magnets of the unit will decrease and the sensitivity will decrease over time!

6. Keep your headphones away from moisture. The pads on the headphones will get rust and the resistance will increase, and the sound quality of your headphones will deteriorate.

7. Plug part. Some friends like to put mp3 on the trouser pocket, and the outlet part of the plug is very easy to fold. It will break for a long time.

8. Do not disassemble. Some people are curious and want to take a look at the headphones. Some headphones are difficult to open, some headphones can not be opened without a special method, even if opened, 80% will make the phone headset can not continue to work or sound quality deterioration.

9. It is best not to use it outside during winter. In winter, the wire is hard, and excessive bending can easily break the wire. Do not heat the headphone cable at this time. High temperatures will accelerate the aging of the wire.

10. Keep away from chemicals. The paint on the earphone casing dissolves in organic chemicals and it does not look good.

11. The best headphones do not suffer exposure, otherwise the line will burn out.

Android data cable manufacturers help you understand more USB type-c interface

August 26, 2019 by keikeilaiy  

The USB Type-C interface is no longer a new topic. The biggest difference between this USB interface protocol and the Type-A for laptops or the Micro-B for Android phones is that USB Type-C supports pros and cons. the design of. Designed by the top left and right symmetry of the 24 feet, half of the positions of the positive and negative insertions can be operated normally. Type-C usage has become more and more popular. Today, USB data cable wholesale manufacturers share the knowledge about USB type-c interface.

 

USB 3.2 transfer rate increased to 20Gbps

 

USB 3.2 announced version 1.0 in September 2017. USB 3.2 will use two pairs of high-speed signal lines of USB Type-C at the same time, which can achieve twice the transmission speed of USB 3.1 Gen2 (10Gbps) (20Gbps); in the past, USB 3.1 Gen1 Or USB 3.1 Gen2 only uses a pair of high-speed signal lines, which can be transmitted in the old USB Type-A interface. The new USB 3.2 needs to use two pairs of high-speed signals at the same time, so it can only be applied to the USB Type-C interface. It is said that it is tailor-made for USB Type-C.

 

The main feature of USB 3.2 is that the transmission speed doubles to 20 Gbps and the USB 3.1 Gen2 line length can reach 2 meters. In the USB Type-C specification, both sides are transmitted in the standard cable of the USB Type-C interface. The length of the wire of USB 3.1 Gen2 speed is less than 1 meter, and the length of the wire for transmitting USB 3.1 Gen1 speed is less than 2 ruler. Through the USB 3.2 technology, the 5Gbps speed is simultaneously transmitted to two pairs of high-speed signals, so that the transmission speed of 10Gbps can be transmitted within 2 meters. For the application of Hub, as the transmission bandwidth of the pair is doubled, each downstream port of the Hub also has the opportunity to reach the full load speed.

 

PPS specification meets fast charging requirements

 

In the past, in order to shorten the charging speed, the charging wattage of the mobile phone was increased by increasing the output voltage of the charger. However, because the step-down line in the mobile phone reduces the high voltage to a low voltage, the efficiency of the mobile phone is charged. In order to solve this problem, it is hoped that the step-down line in the mobile phone can be removed, so that the output of the charger is directly connected to the battery terminal of the mobile phone, and the output can be adjusted according to the fluctuation of the battery voltage, so there is a definition of PPS. When both the charger and the mobile phone are USB Type-C interfaces, the only charging protocol should be PD, and PPS is also developed in response to the current fast charging needs of mobile phones.

What are the major factors that distinguish between power adapters and voltage regulators?

August 20, 2019 by keikeilaiy  

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 strictly prevents third-party battery replacement

August 14, 2019 by keikeilaiy  

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.

How does the mobile phone charger wholesale factory improve production efficiency?

July 2, 2019 by keikeilaiy  

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.
