The USB data cable has become a common and essential digital accessory in daily life. However, with the rapid development of the mobile phone industry, the OTG cable has gradually entered the public's field of vision. The OTG cable is so similar to the USB cable, so what is the difference between them?
The USB data cable is used to connect the mobile phone and the computer. It can access the data such as photos and music in the mobile phone through the computer. At the same time, because the mobile phone has its own memory or expansion card, in a sense, the mobile phone is also another kind of U disk. Of course, it is also an indispensable connection bridge for charging mobile phones, tablets, MP4 and other digital devices.
On major e-commerce platforms, all kinds of data lines are overwhelmed, and people who don't know it will be dazzled. I believe that many people's attitude towards the data cable is: almost, all the same, buy a cheap one. Don't have this idea. Inferior data cables will not only cause damage to the mobile phone, but also infringe on your own safety. So when you buy a data cable, you must not be greedy for petty bargains, and make a mistake and hate forever.
1. Charging speed
Most users are more concerned about the charging speed of the data cable. At present, the most popular one in the market should be Huawei's 40W 5A super fast charging, which is a super fast charging protocol developed by Huawei itself: SCP protocol. Compared with the old Micro connector data cable, the charging speed of the 5A super fast charge has been doubled many times.
