A: 5V 1A and 5V 2A are the specifications of the output current of the charging bank, and the difference between them is mainly the size of the output current, which also affects the charging speed and safety.
< br >
5V 1A: indicates that the output current of the charging bank is 1 amp, which is usually suitable for devices with small current requirements, such as smart wristbands, smart watches, headphones, etc. The output current of the 5V 1A is relatively small and the charging speed is slow, but it is also relatively safe.
< br >
5V 2A: indicates that the output current of the charging bank is 2 amps, which is usually suitable for devices with large current demand, such as smartphones, tablets, digital cameras, etc. Relatively speaking, the output current of 5V 2A is relatively large, and the charging speed is relatively fast, but it is also relatively easy to generate heat and safety hazards.
