    Nowadays, fast charging is the standard equipment of new phones. You can get a fast-charging phone for less than $200. A phone with a high configuration can reach 40W or higher, which can fill a phone in an hour. At the same time, many chargers and cables are named for fast charging, so the question is, does the charging speed depends on the charger or cable?

    Let us talk about the two components for charger and cable of fast charging.

    The charger is the source of current output. it determines the voltage and current, the maximum output power, and also determine the maximum charging power that can be provided to the mobile. The charger of the original factory or big brands can guarantee the full and stable current output.

    The cable’s main function is the transmission of current. The quality of the cable and the performance of the wire also have a certain impact on the charging efficiency. The material of the cable determines the level of current loss during the transmission process. The better the electrical conductivity, the smaller the resistance of the wire, so that the amount of electricity that can be transmitted to the mobile in real-time is more sufficient, and the selection of the general wire of the original factory is strictly controlled. And the charging speed is also related to the material of the cable and the matching with the mobile. Whether there is pure copper in the cable or the number of copper cores in the cable has an impact. If the quantity of cores is large, of course, data transmission and charging will be faster, on the contrary, it will be much slower.

    Then the charging speed depends on the charger or cable? The answer is that both have a certain impact. After all, charging equipment is not only one of them to complete the work, and the fast charging equipment is generally high-power configuration. If the power is not matched, the charging speed and safety will be more or less affected. If you have purchased a fast charging cable, it is best to configure it with a fast charger with the same high performance. If you do not know how to choose high-quality charging accessories, then it is always right to choose a big brand product.

    What is the relationship between charging speed and charger?

    When charging to the mobile, charger determines the voltage and current, voltage and current output are marked on the regular charger. For a very simple example, if your mobile supports 5V/2.4A, that is 12W charging, if the charger is bad, you can change to a 5V/1A 5W, the charging speed will be more than half slow.

    Of course, most mobile brands are equipped with fast charging now, Huawei’s FCP fast charging and SCP super-fast charging, the charging speed can be as high as 22.5W or even 40W. In addition, there are QC3.0 fast charging supported by Xiaomi, AFC fast charging supported by Samsung, and so on. Therefore, if you want to replace the charger, it depends on whether the charger is compatible with the fast charging protocol of the mobile so that the fastest charging speed can be achieved.

    Why does the cable also affect the charging speed?

    When the battery loses water, the battery can still be used after replenishing water according to the regulations.

    The usb cable is responsible for connecting the mobile and charger, and is mainly responsible for current transmission. Therefore, it is inevitable that it will also affect the charging speed.

    For example, the power of a mobile phone is equivalent to a bucket, the charger is a faucet, and the cable is a water pipe. To fully charge the mobile phone is equivalent to filling the bucket with water. Since the charger cannot be directly connected to the mobile phone, it needs to be connected to the mobile phone through the cable. Therefore, the charging speed is not only related to the charger (faucet), but also Look at the length of the cable (water pipe), etc.

    At present, the micro usb cable can generally transmit a current of 2A on the market, but there are also some charging cables without a signal core, which can only charging and cannot transfer data. The current supported transmission is only 500mA, so you need to pay attention when choosing.

    The Type-C cable generally can transmit current of 3A, which can basically be used between various brands. Only the cable that supports Huawei SCP fast charging is more special, and the current that supports transmission is 5A. Due to the different Type-C interface standards, it is impossible to charge other brands of mobile phones with a 5A cable that supports Huawei SCP fast charging. The same is true for other brands of cables to charge mobile phones that support Huawei SCP. The charging power of SCP cannot be reached, but the charging power of FCP can only be reached.

    In addition, the length of the usb cable also has a certain impact on the charging speed. The charging speed is faster for shorter usb cable. Generally, the standard cables of mobile phones are 1 meter, but we can also match cables of different lengths when we choose different usage scenarios. For example, it is recommended shorter cable for charging to mobile phone when using power bank, the cable does not need to be too long in your hand, and the charging speed is faster. Of course, if you want to charge your phone while lying on the bed or on the sofa, this time is more leisurely. You don’t need to consider the charging time too much, you can also use a 1.5m or 2m cable, which is long and convenient to use.

    Fast charging protocol is equally important

    To achieve the effect of fast charging, the fast charging protocol also needs to be consistent. Each mobile phone manufacturer has its own fast charging solution, and the fast charging protocols of different brands of mobile phones are also different. In addition to PD fast charging and QC 3.0 fast charging, there are also Huawei’s super fast charging protocol, OPPO’s VOOC flash charging, etc.

    The compatibility of the protocol determines whether the charger can charging to the mobile phone, the adaptability of power size determines the charging speed. For example, it can be using a 40W PD fast charger to charge an iPhone 8 or above device, because the device supports up to 18W, it cannot achieve 40W; and using an 18W QC fast charger to charge an iPhone will can not achieve 18W, because Apple does not support QC fast charging.

    New trends in the fast charging market

    The emergence of the GaN charger in the past two years has achieved a breakthrough in fast charging technology. it solves a series of charging problems with higher charging efficiency and smaller size.

    Ietcharger launched 65W GaN charger recently, it’s compatible with multiple fast charging protocols such as PD, SCP, QC, PPS, AFC, etc. It can charge 50% of iPhone11 in 30 minutes with PD 18W Type-C interface, USB- Port A can realize fast charging for different Android mobile phones, and the maximum power of 65W can even fast charge laptop.

    Finally to summarize, the charging speed of the mobile phone is the result of the complementarity of the charger and cable. Only when the charger and cable are selected correctly can the optimal charging speed be achieved. Of course, in addition to those mentioned above, the quality of the products must also have an impact on the charging speed. It is recommended that you choose the original or brands products as much as possible when choosing, and the quality is guaranteed.
