Electronic products using USB interface are already plenty. Many computers may not have enough USB interfaces, so USB hubs have become available on the market. The designs of USB hubs also come in various styles. This USB hub clock, for example, combines a USB hub with a clock. It looks more like a clock, with 4 USB interfaces located below the clock. The front displays the time. It might seem a bit silly to place such an item in front of a computer because you can check the time on the computer itself. However, this clock has its special features - you can choose from the time zones of 25 different cities around the world to know the time in other places. Moreover, when you connect it to your computer, it can set the clock's time according to the computer's settings. It is currently priced at $30 overseas.
