There are two directions for fast charge compatibility: one is downward compatibility of fast charge protocol; Second, the device supports a variety of fast charge protocols.
The first way is the backward compatibility of the fast charge protocol, that is, on devices that support high power fast charge, they can also be backward compatible to support low power fast charge, such as devices that support 18W fast charge also support 5V\/2A ordinary charging. This method can adapt to the output power of most chargers on the market, while ensuring the stability and safety of charging.
The second way is that the device supports a variety of fast charging protocols, such as chargers that support QC, PD, PE, MTK and other fast charging protocols, as well as devices that can automatically identify different fast charging protocols, so that users can flexibly use different brands of chargers and devices for business trips and travel.
Because there are many fast charging technologies on the market, and the compatibility between different brands is different, it is recommended to give priority to the original or certified channel brand when purchasing fast charging appliances or equipment to ensure the safety and stability of charging. If you use a non-original or non-certified channel brand, it is recommended to understand its compatibility and pay attention to safety when using.
The answer is as follows: The two ways of fast charging are not compatible
Because different brands of fast charging technology are different, there are different protocols and standards, so it is not compatible
In addition, fast charging technology needs to match the hardware of the mobile phone, if the mobile phone does not support a specific fast charging technology, then it can not be charged
If you want to be compatible with two fast charging methods at the same time, You can buy a charger that supports a variety of fast charging technologies, or use a normal slow charging method and charge gradually
The two methods of fast charging are compatible. Because the current fast charging technology on the market is mainly divided into two kinds, one is high voltage fast charging, the other is low voltage fast charging.
High voltage fast charge mainly uses DC fast charge technology, which can charge the battery at a higher current, so as to achieve the effect of fast charging.
Low voltage fast charging uses a method similar to PD protocol to achieve fast charging by negotiating voltage and current.
These two technologies in the realization of fast charging, but also consider the safety and stability of charging. Therefore, the way to achieve fast charging can be selected according to the specific equipment and needs, in order to achieve efficient, safe and stable charging effect.
According to the principle of fast charging technology, the main principle of fast charging is to let a certain current charge through the charger, the difference between two-way fast charging and one-way fast charging is that the charging method of the charging bank and the mobile phone is different, but the slow charging method is the same. Therefore, this problem can be solved through the adaptive recognition technology of the charging bank
If you have a charger and a charging bank that support two-way fast charge and one-way fast charge, the charger and the charging bank can be connected to achieve fast charge compatibility
Mobile phone fast charging is automatic, the use of the original charger will automatically fast charging, if the phone is QC fast charging mobile phone need to extingul the screen will enter the fast charging mode, if it is DASH fast charging mobile phone as long as the original power can be fast charging
