1, charging status symbol: usually a battery, if the battery is hollow, it means sufficient power, if it is solid, it means that the power is being charged; 2, power identification symbol: the common is 5 or 4 grids of power identification, used to represent the remaining percentage of power, in most cases each grid represents 20% of the power; 3, output current symbol: usually a lightning symbol, used to represent the size of the output current, generally 1A or 2A; 4, output voltage symbol: usually a voltage symbol (V), used to represent the output voltage value, generally 5V or 9V; 5, charging indicator: some charging treasure will have a charging indicator, indicating that the charging treasure is being charged, if it is red, it is charging, green means that charging has been completed.
Through the representation of these symbols, users can easily understand the power, charging status, output current and voltage and other related information of the charging bank.
The symbol on the charging bank includes four parts: power indicator, input port, output port and function key.
The power indicator usually has four or five cells, indicating the remaining amount of power.
The input port is used to charge the charging bank, generally Micro USB port or Type-C port.
The output outlet is used to charge other devices, generally USB ports, and the output voltage will be slightly different on different charging banks. The function key generally has an on key and an LED light, which is used to control the switch of the charging bank and the switch of the lamp.
In short, the symbols on the charging treasure have a clear meaning, the power indicator light and the output are the two most commonly used parts, the user can choose the charging treasure according to the needs and their own equipment to meet their needs.
There are AC and DC symbols on the charging bank, such as the input is AC 220V50Hz, the output is DC 5V1A, etc., which is the key mark. Others are product name, implementation standard and manufacturer information.
