Wired charging
Wired charging is the most common charging method. Generally speaking, a mobile phone charger is connected to the phone through a USB data cable and then plugged into a wall outlet or computer USB port for charging. This method of charging is relatively slow, but is commonly used for daily charging.
Wireless charging
Wireless charging is a relatively new charging method that does not require any physical connection between the input power supply and the charging device. Currently, there are many wireless chargers on the market, most of which use Qi standard. Simply place the phone on the charger to start charging. Because there is no need to plug in a charging cable, it is convenient to use, but compared to wired charging, the charging speed is slower.
Fast charging
Fast charging refers to the use of specialized charging chips to increase the charging speed by increasing the input voltage or current. Currently, many mobile phones on the market support fast charging function. Compared to regular wired charging, fast charging can greatly shorten charging time. However, when choosing a fast charging charger, it is important to pay attention to whether it matches the fast charging protocol of your phone, otherwise there may be issues such as slow charging speed or unstable charging.
Power Bank
Power bank is a mobile charging device that is often used outdoors or during travel. It has one or more built-in batteries that are connected to the phone via a USB data cable to provide power to the phone. The charging method of power bank is the same as wired charging, but it is more flexible and convenient than plugging it into a socket. However, for the selection of power banks, attention should be paid to factors such as capacity and output current.
