Should I use the original charger for Iphone? This is unnecessary, you can use other ones, but you must use the brand name. In addition, Iphone8 and above can be charged quickly with PD protocol, and chargers of other brands need to support PD3.0 protocol.
Why use this brand? Because the brand production has strict factory requirements and has obtained relevant certification. For example, China 3C, European CE certified LVD (safety), American UL certified FCC (safety), Japanese certified VCCL and so on. What are these specific certification requirements? I won't discuss it here. If you are interested, you can consult relevant information.
The black line on the picture is a sign of certification. Now many fake chargers also have this certification mark, because printing is not difficult after all. Next, let's disassemble the difference between the original Apple charger and the cottage charger. The brand will not be discussed today, and the materials and parameters of the works meet the certification requirements.
Let's look at the original charging head first.
This is a 5W charging head with good internal materials and compact structure. The PMW chip comes from Fairchild Semiconductor 30 1H, and has input rectification, * * * mode inductance and Y capacitance to eliminate interference. Optocoupler feedback control output voltage, Li Long electrolytic capacitor, etc. The ripple measured by oscilloscope is very small.
Let's take a look at the internal structure of the shanzhai charging head first.
Shanzhai charger looks much thinner, with output rectification, filtering, driving, isolation transformer and output rectification and filtering. It seems that the difference from Apple is that there is no * * * mode inductance, Y capacitor, optocoupler feedback and so on. In fact, the whole circuit design is very different. The charger ripple of this cottage is very large, which will lead to screen jumping, window popping, fever and even fire when the mobile phone is charging. Some shanzhai charging heads don't even have isolation transformers, so using resistance and capacitance to step down the voltage may cause the danger of electric shock.
The no-load voltage of the shanzhai charger is 5V. Because there is no voltage feedback, the voltage drop is very large after receiving the load, and some of them are only about 4.3V, and the charging is also very slow. The original equipment has voltage feedback, and there is little difference between load and no-load voltage.
From the above discussion, do you know anything about the shanzhai charging head? The charging head has stable voltage, small ripple and safety, and can be regarded as an excellent charging head.
Thank you for reading. I hope my answer is helpful to you.
You don't have to use the original, but you must identify the brand. Different brands are very different, and poor quality can easily damage mobile phones. It is necessary to choose the certified brand, and it is also important to choose the MFI-certified data cable. For example, brands such as Mizi, Lvlian, Netease YEATION, anker and Belgin (more expensive) all have charging heads and data cables suitable for Apple. Purple rice qc3.0 charging head is highly recommended, more than 20 yuan. With the original cable, 12w charging can be realized, with high cost performance.
Besides Apple 7, it supports qc3.0 charging protocol, preferably 5V 2.4A 12W charging. The old iPad charger is this standard, which can charge the iPhone. Pd fast charging is supported after iPhone 8. Officially provided 18w charging head (249 yuan) and usb-c to lightning data cable (149 yuan). Anker and Green Alliance are also launched now.
It is suggested that the landlord consider it according to his own situation.
The more reliable answer is that it is best to use the original charger to charge the iPhone, and try not to use a third-party charger.
Compared with other brands of mobile phones, iPhone has strict requirements for chargers. I use iPhone 8 Plus, and charge my mobile phone with a third-party charger. It was found that the battery health declined 1% after one week. After switching back to the original charger, the battery health did not decline after one week.
Under normal circumstances, the author's iPhone 8 Plus is charged 1 time a day, and the battery health will decline 1% after about 40 days. Obviously, the iPhone's requirements for chargers are quite demanding. To this end, the author suggests charging the Apple mobile phone, preferably with the original charger.
Considering that all mobile phones after the iPhone 8 series support fast charging function, many consumers think that the price of chargers that officially support fast charging is relatively high, and they all buy chargers of third-party brands. In fact, the third-party chargers of some big brands will not damage the battery of Apple mobile phones in normal use, and I have also tested them.
The author has used many iphones and got an experience: using small-brand chargers and miscellaneous charging treasures will affect the health of iPhone batteries.
Hello, I'm glad to answer your question.
Your question is not so absolute. The charging voltage of Apple mobile phone is generally between 3.7V and 4.5V, and the charging current is about1a..
The original charger can effectively and continuously output stable voltage and current, which has a certain protective effect on the charging ic and other circulating circuits of mobile phones.
However, the output voltage and current of the non-original inferior charger are unstable, which will cause the following situations: slow charging, serious heating of the charger, and even direct burning, which will cause a fire and burn out the charging ic of the mobile phone.
Of course, not all non-original products are inferior. You can also choose a non-original charger with a better brand.
Although the iPhone can play the best charging performance by using original charging accessories, it does not mean that it must be charged with original ones. The original filler is 5V 1A standard. As long as it is the same standard, it can be used. Of course, it is best to choose a regular manufacturer. After all, the materials produced by small workshops are of poor quality and unstable. Data cable requirements are relatively low, and ordinary cables can also be charged, but sometimes there may be problems that this device knows nothing else. At present, some brands of wires on the market are also MFi certified (such as Bull). These wires use the same chips as Apple's original factory, so they are no different from the original factory.
In fact, as long as the battery is properly maintained, it can maximize its benefits. Let's talk about it briefly:
1. Do not charge the device after it is exhausted.
Lithium polymer battery has no memory effect and does not need to be completely discharged. It can be charged as needed to avoid overcharging. If the equipment is idle, it is best to keep the power above 50%.
2. Minimize the use of third-party battery management applications.
Some application software for battery maintenance will constantly detect the current power of the equipment during use, causing unnecessary loss and increasing the temperature of the fuselage, which is difficult to play a practical role except increasing the extra burden on the battery.
3. Check the power consumption application regularly.
Enter "Settings"-"Battery" to view the battery usage and power ranking in the last 10 day, and choose to close unnecessary "background applications" as needed.
4. Avoid charging equipment in high temperature environment.
High temperature environment will accelerate the aging speed of electronic components, make lithium batteries unstable and prone to potential safety hazards. Avoid charging in high temperature environment, which can not only maintain the battery, but also ensure its own safety.
No need to charge with the original charger! But if you use inferior charger, it may cause harm to your mobile phone. In order to reduce the cost, these chargers will lead to unstable output current and voltage, fail to meet the standards, and fail to provide good trickle charging, which may cause harm to mobile phones.
As long as you don't buy small brands, using a third-party charger is fast and cheap.
Inferior chargers will have security risks: assembling chargers may have some quality problems and security risks. Some mobile phones exploded some time ago because of the quality problems of chargers. The original charger and the non-original charger are different. If the current and voltage are not in the range, both the original charger and the charger will cause some damage to the battery. The difference between original charger and non-original charger lies in the different damage to battery. The parameters of the general charger can be used in the following range: 1. The output voltage is 5.0~5.5VDC2, and the output current is 500~800mA. This charger charges the mobile phone, which has a charging control circuit. As long as the voltage and current do not exceed this range, it is the same. In addition, there are differences in efficiency between chargers, but it has no effect on mobile phones.
It is recommended to buy original chargers as much as possible.
The production process of non-original charger is not so high, which may have potential safety hazards. In addition, there is basically no warranty for non-original chargers after use, and the official original after-sales warranty.
In addition, the same is true for batteries. It is recommended to use original batteries. After testing all kinds of mobile phones for a long time, we found that, for example, the official original battery can charge and discharge for about 500 times, while the non-original imitation battery generally charges and discharges for 300 times or even less, so this is why most original batteries obviously lack standby after being used for about 2 years, and the battery life is basically 500 times.
The theme of this question is too absolute. We can only say that we should use the original charger to charge the iPhone as much as possible, because using the original charger for electronic equipment is conducive to protecting the charging circuit and charger of the mobile phone and reducing the occurrence of safety accidents.
Even if you use a third-party charger, you must look for the same 5V 1A as the original charging standard, and try to choose one that has passed MFi certification. Otherwise, long-term use of substandard chargers will easily lead to charging and heating of mobile phones, shorten the life of mobile phones and even damage them.
Another point is to develop good charging habits. For example, playing a large mobile game while charging will greatly occupy the CPU, causing the phone to heat up. Excessive temperature has a great influence on lithium batteries; If you often wait until the battery runs out, it will also accelerate the loss of the battery, because the loss of lithium batteries is relatively large when the power is low, and usually the mobile phone needs to be charged when the power is 20%. These are all things that we usually need to pay attention to ourselves.
First of all, the iPhone does not have to use the original charger, as long as it is suitable for the iPhone socket.
It is harmful to the internal battery of mobile phone to charge different output power with different chargers.
Apple's mobile phone charger will automatically power off when you are fully charged while sleeping.
Other famous brand chargers will discharge current first and then charge and discharge, which will reduce the life of the circulating battery.
Therefore, users are advised to use the original charger in order to ensure that the mobile phone can be used for a long time.
