The transition from the old USB port to the new USB-C interface has also undergone a long and painful process. But the updated design has led to a large number of new products that need to be redesigned for this specification.

The biggest reason is that USB-C can charge your phone and laptop - Apple MacBook, Google Chromebook Pixel, or higher end models from Dell and HP. Even more and more devices can charge Bluetooth wireless headphones, mice, Nintendo game controllers, and MiFi portable hotspots.

This means that a charger or power bank is useful in many cases. You don't need to prepare different chargers for different electronic devices anymore. If you are on the road, you can connect your laptop charging cable to your phone and then move it back to fully charge both devices.　　

USB-C is a universal connector for data, power, and video, suitable for all device platforms from Mac to PC, iOS to Android, smartphones to computers, and actively promoting the use of USB-C and a series of power and data accessories.

Another major benefit of USB-C is that more powerful devices, such as laptops or tablets, can charge smaller devices such as smartphones. This way, when you can't find the power plug, it can provide you with power and help you get out of trouble. For old-fashioned USB devices, charging is a convenience that can only be useful for mobile phones;; But USBC power supply technology - you often see the "PD" sign on accessory boxes and port labels - can charge up to 100W, enough for high-end laptops.　　

　　
In the past 20 years, there have been issues with migrating rectangular USB-A ports and smaller USB Micro B ports on desktop computers. Old or cheap devices usually use old USB interfaces, so we still have a long way to go before we have a universal port. Airports, airplanes, hotels, cars, and other charging locations rarely provide USB-C charging ports, so you need to prepare additional chargers and power plugs.　　

The iPhone and most iPads still use Apple's proprietary Lightning interface. The iPad Pro models of 2018 and 2020 used USB-C, so perhaps future Apple products will benefit from the popularity of USB-C, but Apple has not made a leap on the iPhone 11 or iPhone.

USB-C (officially known as USB Type-C) can help you convert from old-fashioned USB Type-A. In daily life, we often see the USB-C interface; Pure USB-C charging, not data transmission.　　

Changing the wall charger from USB-A to USB-C usually means that the device charges much faster. When charging phones, tablets, and other small devices, please choose between 18W and 30W, but for most laptops, you will need to use a 60W or higher "PD" (power transfer) charger.

The Type-C plug converter multifunctional conversion plug looks no different from a charger, mainly for international travel convenience. But this travel converter has a 28W USB-C charging port and two USB-A ports, which means you can charge your phone while also plugging it into your laptop. The power plug converter can be plugged into wall sockets in hundreds of countries such as the United States, Europe, Japan, and Australia; And the modular multi-purpose socket design can be compatible with electrical plugs from hundreds of countries!
