Product Q & AQuestion: Why doesn't my mobile hard drive work anymore?
Answer: Mechanical hard disk, solid state hard disk, etc. are high-power devices. The power of the full load state is 2~10W. External PD power supply is needed to ensure the normal use of device-related functions. Conventional U-disks, mice, keyboards, etc. are small power devices that can be plugged in directly.
Question: Why cannot my mobile phone play videos from the USB drive through this USB hub?
Answer: Mobile phones and tablets need to support OTG protocol. The compatible mobile phones example: Samsung Galaxy S8/S9/Note8/Note9 and so on. For more information, please check the official website of the mobile phone.
Question: Why does the product feel hot when used?
Answer: When electronic products are used, heat will be generated. The body of this product is an aluminum alloy shell, which can quickly export the heat to the surface. When the product is fully loaded, the temperature of the metal shell is about 55 degrees Celsius / 131 degrees Fahrenheit (the temperature of the experimental environment is 25 degrees Celsius / 77 degrees Fahrenheit). According to gb4943.1-2011 standard, the metal material of the equipment held in a short time shall not exceed 60 degrees Celsius / 140 degrees Fahrenheit. The temperature is within the standard range, so please feel free to use it.
