Generally, af first the mobile phone chargers we used are original chargers when bought cellphone, but sometimes we switch to other chargers, in following situation:when we go out for emergency charging, when we borrow other people’s chargers;when we use the tablet charger to charge the phone;when the original charger is damaged, buy a third-party brand charger.etc.
What about the output powers of various mobile phone chargers? What should be paid attention to when charging with different chargers? If you pay attention and look carefully, you will find that a charger may be marked with different output power, and the output power of different brands of chargers is also different. What kind of specification does your charger have?
How to know the output powers of mobile phone chargers? What should be paid attention to when charging with different chargers?
For the total power,bascially all chargers will print bassic information like output:5v/2a,5v/3a,9v/2a,which namely means out put power will be 10W,15W,18w. Some normal charge only write 5v/2a ,that means the output power only 10W,but some fast charge will write 5v/2a,5v/3a,9v/2a together,that means this charger support fast charger,and the output will auto adjust based on the different cellphones,tbe remaining power of cellphone’s battery. If only 5% ,the output may will be max speed like 18w,if 90%,the output will be slow like 10W to protect the battery.
The following is the mainstream output power of mobile phone chargers
The output power,which is 5V/1, at present, is most suitable for mobile phone for iPhones, or some cheap Android phones less 1K RMB, such as Huawei Enjoy 7s and Honor 8 Youth Edition.
The 5V/2A ,born by QC1.0, is currently the standard output power, and many mainstream low-end and mid-end models mobile phone use charger with this charging specification.
The Qualcomm QC2.0, the mainstream voltage specifications are 5V/9V/12V, and the current specifications are 1.5A/2A;
The Qualcomm QC3.0，voltage specifications range from 3.6V-20V, normally output will be 5V/3A, 9V/2A, 12V/1.5A , Mi 6 and Mi MIX2 are the main representative cellphone models.
The Qualcomm QC4.0, the overall power could be max 28W,like 5V/5.6A, or 9V/3A. In addition, the upgraded version of Qualcomm QC4.0+ is currently only supported by a few mobile phones, such as the Razer Phone.
In addition to the above specifications, the Meizu mobile phones have many modes such as mCharge 4.0, 5V/5A; mCharge 3.0 (UP 0830S), 5V/8V-3A / 12V-2A; mCharge 3.0 (UP 1220), 5V /8V/12V-2A .
Besides,there are other output power,5V/4A and 5V/4.5A, mainly for OPPO’s VOOC flash charging, OnePlus’ DASH flash charging and some major flagship phones of Huawei Honor.
What is the output specification of your mobile phone charger? If you borrow someone charger, or buy a new third-party charger, which charger is more suitable for your mobile phone?
What should I pay attention to when using non-original chargers for mobile phones?
When the mobile phone is charging,the mobile phone itself will determines the charging current.So when charging, the mobile phone generally automatically detects the load capacity of the charger, then determines the current input according to its own power. But I have to say that there are some charging issues that still need notice.
1. When using a high-power charger to charge a low-power mobile phone, is it harmful to the mobile phone? The harm is very small, because the mobile phone has the function of current self-adaptation. Therefore, when the mobile phone is in the charging mode of 5V/2A, if a 9V/2A charger is used to charge the mobile phone, the charger will automatically recognize the charging specification of 5V/2A. Another example is that a high-power iPad charger can charge a low-power iPhone, and it will also work with the current standard of the iPhone.
2. If a low-power charger charges a high-power mobile phone, will it hurt the mobile phone? It does not hurt the phone if it has a protocol. For example, the iPhone 8 supports fast charging, but if it is equipped with a 5V/1A charger protocol, this will not affect it. If there is no agreed charger, the charger will be a “little horse and a big cart”, working at full speed, causing the phone to heat up and hurting the charger. So generally, don’t use 5V/1A chargers to charge 5V/2A and higher power mobile phones.
4. When the fast charging charger charge the non-fast charging mobile phone, will it damage the mobile phone? At present, some fast charging chargers on the market, in addition to the fast charging power, will also retain the standard charging power of 5V/2A, such as Huawei’s P10, Samsung’s S8 and other mobile phones. This setting is mainly to prevent us from using the fast charging charger on mobile phones without fast charging function, which main damage the mobile phone.
