Nowadays, mobile phones occupy more and more people's time, and work and leisure are inseparable from mobile phones. Therefore, despite the current growing battery capacity of mobile phones, people still can't meet the demand for electricity. This involves charging the phone.
Different charging demand scenarios, people have different requirements on the length of the mobile phone data line. Is the data line as short as possible? The longer the data cable will be charged, the slower it will be? Today, STC-Cable come to talk to you.
The cell phone data line transmits power through the inner conductor copper wire core. According to the physics knowledge of middle school, the conductors all contain resistance. In theory, the shorter the wire, the shorter the conductor, the smaller the resistance, and the smaller the loss due to heat during the power transmission; on the contrary, the longer the data line of the mobile phone, the greater the loss. Then the charging speed becomes slower.
STC-cable's mobile phone data cable adopts tinned copper core technology and built-in aluminum foil + aluminum woven mesh multiple shielding to ensure mobile phone charging and data transmission without interference. At the same time, for long-size data lines (1.5-3 meters), GreenLink uses thicker copper core conductors to ensure minimum resistance of the cell phone data line. Under strict quality standards, even if the STC mobile phone data cable reaches a length of 3 meters, its charging speed is consistent with the short-term, and charging will not slow down.
Take the MFi certified data line as an example. According to HUAWEI's MFi certification requirements, STS has a wire resistance of less than 100mΩ:
0.25-1.2 meters length, wire gauge 2.6mm
1.5-2 meters length, wire gauge 3mm
The high-standard wire core is adopted by the long data line to ensure that the STC USB Type c data line has a smaller resistance, thereby meeting the fast charging demand of the Android cell phone product.
Actual comparison test: Charge the HUAWEI P20 through the STC MFi certified data line, compare the other non-MFi data on the market to charge the HUAWEI P20, and increase the charging efficiency of the STC data line by more than 25%.
The speed of mobile phone charging is determined by many factors, such as mobile phone data cable, USB charger and charging treasure output power, and even the environmental factors of charging. Choosing a mobile phone data cable should try to choose a brand with excellent quality. Even a long mobile phone data cable will not slow down the charging speed.
