Car charger equals time bomb? How to choose not to hurt the mobile phone?
Car charger is now a necessary necessity for every family to travel. It is inevitable that when you go around with mobile phones, you will need charger. If you don't know how to go through the road without car charger, you will find the plug when you get to the service station; However, some of the charging treasures or car chargers on the market are not in pace with the mobile phone charging protocol. Some people use it, not only slow charging, but also the cell phone battery is hot.
Even some mobile phone sales don't know how to pretend to understand, which is the most they say: "what do you buy a charging treasure with such a large current? The current is a little bit friendly to the battery! We do not provide more than 2A. If you want more than 2a, you wait for the cell phone to explode! " These words, undoubtedly let mobile phone white into panic state.
These bullying mobile phone people, seemingly bully our consumers in a threatening way all day. In fact, their backward ideas also strongly persuade consumers to instill old ideas, which leads to the car friends dare not choose a large current car.
Commune gentleman here to give you a wake-up, in fact, the high-power car charger is not so terrible, as long as the regulations, the product is qualified, car charger is also safe. As a public official account for the society and the riders, the commune king here teaches you how to choose a car charger. I hope you can understand the charging current and charging protocol of your mobile phone through this article. If you choose the right car, you will not worry about your trip.
It is not so difficult to understand the charging protocol of mobile phone and the charging protocol of your mobile phone. With the development of science and technology, the fast charging charger of mobile phone appears, which can charge a lot of electricity in a short time. However, in the case of low current, the fast charging protocol will hurt the battery once it is incompatible. Without trickle protection, hard current is applied. Charging in the back section is still so direct, which will also cause damage to the battery.
"Charging agreement" is a common sense that some people who sell mobile phones lack, and some car friends (consumers) do not know the charging agreement. Charger is a fast charging and slow charging protocol. It has bc2.0, QC 2.0, QC 3.0, QC 4.0, Huawei FCP, SCP, and even oppo vooc, vivo dual engine flash charging, PD 3.0, Samsung AFC, etc. If the charging protocol is compatible, the charger handshakes with the mobile phone successfully, and the charger will output the fast charging current to the mobile phone, and charge the phone with the appropriate current. If not compatible, the charger does not support the protocol, it will charge the phone with 5V - 2A voltage and current.
For example, commune Jun's mobile phone is a charging protocol of Qualcomm QC 3.0. If QC 3.0 connector is used, the mobile phone will identify the "fast charging connected" screen. If PD is used, the mobile phone will also identify because part of the fast charging protocol covered by PD is supported. If other brands are used for charging, such as Huawei's SCP, Huawei SCP can only charge the mobile phone with 2.1a or 2A current because it does not support the fast charging protocol of other mobile phones. Although it can be filled with mobile phones, the current is very direct "pouring" to the cell phone battery. For a long time, the battery will be hot.
You must know the working current of your mobile phone charging
This is also a must to know, for example, the mobile phone of commune Jun is xt1929-15 of moto, and the charging current is 5V - 3a, 9V - 1.5A, 12V - 1.5A. Why is there slow current? Because the charging chip of charger will have so-called trickle protection, but this does not mean that the mobile phone of commune Jun can be charged with 1.2 and 1.5A. Too small current, the charging speed is also slow, too direct current output may also cause damage to the battery and cause heat. The current of the original factory charger will also drop a little under certain circumstances to protect the battery. But if you don't play with your mobile phone crazy, the background takes up less and the charging efficiency will be higher naturally. Today, the current that fast charging technology can support can go to 5A, but it is also a controversial topic. Many people always say that too much current is bad for cell phone batteries. Indeed, current overload is indeed not friendly to some cell phones' batteries. But the current battery design is more and more safe, as long as the current is distributed according to the agreement to charge the mobile phone, it will not damage the battery. If not compatible, no less current, no protection, the same damage to the battery.
Another, if the mobile phone has been used for several years, it is older and does not support fast charging. Only when these old phones are used, they are recommended to choose the same charger as the charging current of their original cell phones. So some people will have the old idea of "slow charging is battery friendly".
Many of the goods avoided from the stall are OEM fake goods, which are "underground goods" produced by unknown manufacturers or black center businesses. Some underground black goods are not only marked by charging protocol and charging current, but automatically operated after connecting mobile phones. Even some even have a small current that doesn't charge much electricity at all. Moreover, some car chargers even have no security. If there is no security guarantee, a less charging barrier will not only threaten the safety of everyone's life, but also lead to the fever of mobile phones. If you buy a large brand car, the charging safety is guaranteed, the circuit of the car is not damaged, and the car is not overheated. Everyone's travel is guaranteed, and less worry.
The three tips of commune Jun have arrived here. In this place, we hope that all the car friends will take a rigorous attitude like Germany, choose the correct, safe, current and charging protocol car charger that is correct, safe and in accordance with their mobile phone and charging protocol. The charging of mobile phone is as friendly to the mobile phone as the original charger, and the cell phone battery can also live long life. With the rapid development of technology, the charging protocol of mobile phone will be updated. Faster, safer charging will come out later. In order to avoid the promotion suspicion, the commune gentleman here does not recommend.
