If only powered by batteries, the batteries need to be replaced frequently. So we use a USB cable instead of batteries. On the one hand, it can reduce the use of batteries and protect the environment. On the other hand, it can be connected to an adapter, power supply, or computer via the USB cable, which is very convenient. 6. The digital wall clock is quiet and does not produce noise that can interfere with study and rest. It is an ideal choice for hanging in classrooms, libraries, and offices. At the same time, it is very light and can be easily hung on the wall without easily falling. It also has a hidden stand and can be placed on a bedside table or a desk.
