Generally speaking, iPhones have a charging port, however, some custom versions of iPhones may remove the charging port for better waterproofing. If you unfortunately encounter an iPhone without a charging port, don't worry too much, because Apple has already thought of this for you, and you can charge it wirelessly.Wireless charging is a very convenient way of charging, you just need to place your iPhone on the wireless charger to easily charge it. Of course, to ensure the effectiveness and safety of wireless charging, you need to choose a reliable and Apple compliant wireless charger.If you don't have a wireless charger, don't worry, as Apple also offers a magnetic charging solution called MagSafe. With MagSafe, you can securely attach your iPhone to the charger and then charge wirelessly. MagSafe chargers not only provide a faster and more efficient charging experience, but also reduce the generation of heat inside the phone.In addition to wireless charging and MagSafe charging, yo...

In today's electronic world, power plays a crucial role. The push-pull switching power supply has become an ideal choice in many fields due to its unique advantages. Whether in precision instruments, communication equipment, or consumer electronics and household appliances, it has demonstrated excellent performance and reliability.Operational principle of push-pull switching power supplyThe direct current at the input end supplies power to the power supply pins of the chip through the startup circuit, and the VDD charges the capacitor after being powered on. When the operating voltage of the chip is reached, the chip begins to work, and the OUTA outputs a high level. The upper MOSFET conducts, and the current flows through the main winding of the transformer to charge the lower capacitor. The transformer converts electrical energy into magnetic energy, while the output winding converts magnetic energy into electrical energy for the load. After the upper MOSFET conducts for a period of...
Nowadays, smartphones have a wide range of functions, including video calling, drama watching, gaming, socializing, and shopping. Daily entertainment and life can be easily handled with just one phone. The fast charging capacity of mobile phones has increased from 18W, 27W, 40W, to 65W, 120W, and the charging speed has been steadily increasing. The fast charging capacity is related to the user's mobile experience. Everyone is complaining about the high cost of the quick charger on the official Apple website. Here, I would like to share the ranking of third-party chargers of Apple.1.Nank Charging Head C1The Nank Charging Head C1 charging head is a recently popular fast charging head brand, which was recently praised by major digital media as the "Best Charger for iPhone 12" in 2021. Its internet celebrity temperament and explosive sales have been once again elevated and recognized.In terms of configuration, this compact and lightweight charging head weighs only 42g, which is about 40%...
1.Can I use a third-party laptop charger? Normally, third-party laptop chargers can also be used, but the prerequisite is that the voltage, current, power and other parameters corresponding to the interface of the power adapter need to be the same as the original charger, otherwise it may cause damage to the computer. If you are unsure if a third-party charger is suitable for your laptop, please first understand the charger parameters of your laptop and choose a third-party laptop charger that meets the specifications when purchasing.2.What should I pay attention to when choosing a third-party laptop charger?(1) Power adapter parameters. When choosing a laptop battery charger, the first step is to determine the power adapter parameters of your laptop, including voltage, current, and power. If these parameters do not match, neither the original charger nor the third-party charger will function properly.(2) Brand and quality. To ensure the quality and reliability of the charger, it is...
Fast charging technology refers to the technology that shortens the charging time of devices such as electric vehicles or mobile phones by increasing charging power. The principle of fast charging technology is based on the power formula P=UI, where power equals voltage multiplied by current. To achieve fast charging, it is necessary to increase the charging voltage or current, or both. At present, there are two main fast charging technology solutions on the market: high voltage fast charging and high current fast charging. This article will introduce and compare these two solutions, analyze their advantages, disadvantages, and development trends.High voltage fast chargingHigh voltage fast charging refers to a technical solution that improves charging power by increasing charging voltage and reducing charging current. The advantages of high voltage fast charging are lower technical difficulty, lower cost, lower heat generation, and lower requirements for cables and interfaces. The dis...
