Why do so many people use USB extension cables? What's the use? You know what?
Many people like to play with their mobile phones in bed. After a long time, they need to charge their mobile phones when they are out of power. They can't reach them when they plug in the charger. Is that too much for you who can't live without your mobile phone!
Now we can connect the extension cable with USB interface to the mobile phone charger, so we don't have to worry about the insufficient length of the mobile phone charging cable. No matter you are lying or sitting, even if you roll around on the bed, you won't be embarrassed to be unable to charge!
