As smartphones become more popular and more powerful, the performance requirements for mobile phone battery life and charging speed are getting higher and higher. The charging power of the earliest mobile phones has gradually increased from the initial 10 watts (5V/2A) to the current 200 watts (20V/10A).The initial method of increasing power was to increase the current to achieve power increase.
Following are the reasons Why 65W Charging is Made Possible and how it is faster than regular chargers:
Since the current flowing through the mobile phone socket and USB cable is limited, if you want to obtain greater power conduction capability, you have to consider increasing the charging power by increasing the current and voltage at the same time. Increasing the current does not have much impact on the mobile phone end. Increasing the voltage will make it difficult for the power supply end, because the compatibility of different models of mobile phones and different brands of mobile phones must be considered. The older the mobile phone, the closer the charging voltage will be. 5V transmission method.
Because we all know that the general rated voltage of a single-cell lithium battery is 3.7V, and the state voltage when fully charged is also 4.2V. If you want to smoothly convert the power of high-current and high-voltage output to achieve fast charging, this time A fast charging protocol is needed to achieve this.
The fast charging protocol is a communication bridge between the mobile phone and the power supply. When the mobile phone is connected to the charger, it first starts with 5V power supply, and then the mobile phone protocol chip starts to send instructions to tell the power supply that it can receive the fast charging protocol, and then the power supply The terminal responds to the maximum voltage and current it can output according to its own protocol chip. The mobile terminal selects and discards the out-of-range fast charging power standard based on the maximum output power of the power supply protocol chip. It accepts the instructions from the power supply terminal and then responds to start. It requires back and forth questions and answers. After seeking common ground and eliminating differences, the fast charging mode is turned on.
The fast charging prompt we usually see on the mobile phone does not necessarily realize the actual fast charging function, because this prompt is a handshake performance between the power supply end and the mobile phone protocol chip. It is for this reason that many copycat chargers have To seize this business opportunity, reduce the actual output power of the transformer and the power of the gallium nitride MOS tube, thereby saving a lot of costs, and win the favor of ordinary consumers with low-price sales.
Because ordinary consumers have no way to measure the actual fast charging power, they mistakenly believe that buying a charger with the same power is much cheaper. Only a professional protocol load analyzer can truly identify the authenticity of the product.
So how do fast charging chargers on the market avoid these pitfalls? As ordinary consumers, there is no need to worry. You can rest assured to buy products with certification marks, such as 3C, UL, TUV, PSE, LVD and other international markets with mandatory market access certification, because only products that have been actually measured and issued certificates by these authoritative certification agencies Mobile phone chargers are up to par.
The mobile phone fast chargers of major brands are fully matched in terms of power. The actual output power of some brands will be 20% higher or more, in order to create a better reputation. Therefore, ordinary consumers only need to check the certification number and the corresponding certified product online before purchasing to identify the authenticity of the product!
Yes, 65W charging is safe when used with certified chargers and compatible devices. Modern chargers feature safety protocols like temperature control, voltage regulation, and overcurrent protection. Always choose chargers with certifications such as UL, TUV, or PSE to ensure safety. Avoid counterfeit products to prevent overheating or device damage.
Yes, 65W fast charging may slightly impact battery health over extended use, as higher charging speeds can generate heat. However, most modern devices are equipped with advanced battery management systems that minimize heat and optimize charging cycles to reduce wear. Using certified chargers helps maintain battery longevity while enjoying fast charging benefits.
As fast charging technology continues to evolve, it's essential for consumers to be aware of the complexities behind mobile phone chargers and their actual charging capabilities. While the fast charging prompt on your device may appear to indicate optimal performance, it's important to understand that it’s just a handshake between the charger and the phone’s protocol chip. To avoid falling for misleading claims, always choose chargers with recognized certifications like 3C, UL, TUV, and PSE. These certifications ensure that the product has been tested and meets the required safety and performance standards. By being cautious and informed, you can enjoy faster, safer charging while avoiding counterfeit or underperforming products.
