Does the longer the cell phone data line, the slower it char

Nowadays, mobile phones occupy more and more people's time. Mobile phones are indispensable for work, leisure and entertainment. Therefore, despite the increasing capacity of mobile phone batteries, people still can not meet the demand for electricity. This involves the charging of mobile phones.

Different scenarios of charging demand, people have different requirements for the length of mobile phone data line. Is the shorter the data line, the better? Will the longer the data line, the slower it will charge? Come and talk to you today.

Mobile phone data lines transmit electricity through copper conductor cores. According to middle school physics knowledge, conductors all contain resistors. In theory, the shorter the wire, the shorter the conductor and the smaller the resistance, the smaller the loss due to heating in the process of power transmission; on the contrary, the longer the data line of mobile phone, the greater the loss, the slower the charging speed.

The data line of mobile phone adopts tin-plated copper core technology, with multiple shielding of built-in aluminium foil and aluminium braided net, to ensure that the charging and data transmission of mobile phone are not disturbed. At the same time, for long specification data lines (1.5-3 meters), Greenland uses thicker copper conductors to ensure the smallest resistance of mobile phone data lines. Under strict quality standards, even if the cell phone data line reaches 3 meters in length, its charging speed is consistent with the short line, and charging will not slow down.

Take MFi certification data line as an example, according to the requirements of Apple MFi certification, wire resistance is less than 100 m:

0.25-1.2 m in length and 2.6 mm in gauge

1.5-2 m length, line gauge 3mm

Use high-specification cores for long data lines to ensure that the resistance of Greenland's iPhone data lines is smaller, so as to meet the fast charging demand of Apple products.

Actual comparative test: Compared with other non-MFi data on the market, the charging efficiency of the data line increased by more than 25%.

The charging speed of mobile phone depends on the interaction of many factors, such as data line of mobile phone, USB charger, output power of charging treasure, and even the environmental factors of charging location. The choice of mobile phone data line should try to select the brand of high quality, even if the long mobile phone data line will not slow down the charging speed.
