In life, we always encounter various small problems or emergencies, such as lying in bed and brushing the mobile phone when we are at leisure, but because the phone charging line is not long enough, we need to keep the same posture for dozens of minutes to fully charge the battery, which makes the original simple idea impossible!
For another example, if you want to read the files in the USB flash disk, look down and find that there is no USB interface in front of the computer host! Only stoop under the table and move the host out to insert the USB flash disk into the interface. You have to do it again when pulling it out!
Another case is that when you insert a USB flash disk, keyboard or mouse into the interface, it suddenly fails and there is no response. The boss is waiting for your report file. After checking, it is found that the interface is damaged due to long-term plugging!
At this time, it is perfect to have a magic tool that can extend the charging cable at will or extend the interface to the desktop to protect the original interface of the computer! To solve these problems, we need a USB extension cable.
