This digital wall clock features high-contrast numbers that are clear and easy to read, even from 10 meters away. It can switch between 12/24-hour format. The time is accurate and user-friendly for the elderly and children. 2. 3 Adjustable Brightness: This digital wall clock has automatic/manual brightness adjustment with three brightness levels to meet different needs. The brightness can be adjusted according to the time of day; at night, the brightness can be lowered to avoid disturbing rest and sleep, while during the day, it can be increased for easy reading. 3. Multifunctional Digital Wall Clock with Large Display and Long USB Cable: Includes time, date, humidity, temperature (switchable), and alarm functions. It can monitor time, temperature, and humidity from multiple angles and plays a role in monitoring your living environment. However, setting the alarm is not its primary function. 4. As is known, LED displays consume a lot of power. If only battery operation is used, frequent battery changes are required. Therefore, we use a USB cable instead of batteries. On the one hand, this reduces battery consumption and protects the environment. On the other hand, the USB cable allows you to connect it to an adapter, power bank, or computer, which is very convenient. 5. This wall-mounted digital clock is silent and produces no sound that would disturb study or rest, making it ideal for hanging in classrooms, libraries, and offices. It is also very lightweight, allowing for easy wall mounting and preventing it from easily falling off. It has a hidden bracket, so it can also be placed on a nightstand or desk.
