Car charger has now become every family travel must have the necessity, everyone mobile phone navigation around will inevitably need the charger, no car charger, I do not know how to go halfway, once to the service station is everywhere to find the plug; However, some charging banks or car chargers on the market cannot keep up with the pace and are not compatible with the charging protocol of mobile phones. Some people not only charge slowly after using, but also heat up the cell phone battery.
Even some mobile phone sales do not understand pretend to understand, this is the most they say: "Why buy the current so big charge bank? Current dots are battery friendly! We don't offer above 2A. If you ask for more than 2A, expect your phone to explode!" These words, no doubt let the mobile phone white into a state of panic.
These mobile phone bullies seem to bully us consumers in a threatening way all day long. In fact, it is their concept of backward and strongly persuade consumers, forced to instill old ideas, resulting in car friends dare not choose large current vehicle.
In fact, high-power car charger is not so terrible, as long as the regulations, products qualified, car charger is also safe. As a responsible public account for the society and the car users, commune Mr. Here to teach you how to choose car charger. I hope you can correctly understand the charging current and charging protocol of your mobile phone through this article, choose the right vehicle, and you will have less worry about your travel.
Know your phone's charging protocol
It's not that hard to know your phone's charging protocol. With the progress of science and technology, the mobile phone fast charging appliances appear, in a short time can be charged a lot of electricity. However, fast charge batteries at low current conditions, if the charging protocol is not compatible, the battery will also hurt. There is no "trickle protection", hard charging current, to the rear section is still so direct charging, will also cause damage to the battery.
Charging agreement is a common knowledge that some mobile phone sellers lack, and some car users (consumers) do not have a specific understanding of charging agreement. The charger is a fast charge and slow charge protocol, slow BC 2.0, fast QC 2.0, QC 3.0, QC 4.0, Huawei FCP, SCP, even OPPO VOOC, VIVO dual engine flash charge, PD 3.0, Samsung AFC and so on. If the charging protocol is compatible and the charger successfully shakes hands with the phone, the charger will output a fast charging stream to the phone, charging the phone at the appropriate current. If it is not compatible and the charger does not support the protocol, it will charge the phone at 5V-2A voltage and current.
For example, the phone of Gonghe-jun uses Qualcomm QC 3.0 charging protocol. If you use QC 3.0 connector, the phone will recognize the screen saying "Fast Charge is connected." If you use PD, the phone will also recognize it, because some of the fast charge protocols covered by PD are supported. If you use a charging device of another brand, for example, Huawei SCP, the SCP of Huawei does not support the fast charging protocol of other mobile phones, and can only charge the mobile phone at 2.1A or 2A current. Although it can be full of mobile phones, but the current is very direct "perfusion" to the mobile phone battery, a long time, the battery will heat.
You must know the working current of your phone charge
This is also a point that must be known, for example, Konojun's mobile phone is MOTO XT1929-15, charging current is 5V-3A, 9V-1.5A, 12V-1.5A, why there is a slow current? Because the charger charging chip will have the so-called trickle protection, but this does not mean that Commune Jun's mobile phone can be fully charged with 1.2, 1.5A, too small current, charging speed is very slow, too direct current output, may also cause damage to the battery, leading to fever. The current of the mobile phone's original charger will also drop a bit under certain circumstances to protect the battery. But if not crazy play mobile phone, background occupation less, charging efficiency will be higher naturally. Today's fast charge technology can support current up to 5A, but this is also a controversial topic, many people always say that too much current is bad for mobile phone batteries. Indeed, current overload is indeed unfriendly to some phone batteries. But battery designs are becoming more secure, and as long as the current is allocated to charge the phone according to the protocol, no damage will be done to the battery. If not compatible, no matter how small the current, no protection, the same damage to the battery.
Another, if the phone has been used for several years, relatively old, does not support fast charging, these old mobile phones to choose the same charger as their original mobile phone charging current. So some people have the old idea that "slow charge is battery friendly".
Avoid street stalls
Many stall goods are branded fake goods, are unknown manufacturers or unscrupulous businesses produced "underground goods", some underground goods not only do not mark the charging agreement, charging current, mobile phone connection after automatic operation. In some cases, the current is so small that it doesn't charge much at all. Moreover, some car chargers even have no safety guarantee, once there is no safety guarantee, less a charging barrier, not only threaten everyone's life safety, but also lead to mobile phone fever. If you buy a big brand of car, charging safety is guaranteed, do not damage the car circuit, do not overheat, everyone's travel is guaranteed, worry a little less.
I hope you can be as rigorous as the Germans and choose the correct, safe and in line with the current and charging protocol of your mobile phone charger. The charging of the mobile phone is just like the original charger, which is friendly to the mobile phone, and the mobile phone battery can also have a long life. As technology advances at a rapid pace, charging protocols for mobile phones are updated. Faster and safer charging is on the way.
Friendly reminder: you car friends on the road to drive more careful, pay attention to the road conditions, for the safety of you and your family, less mobile phone!
