Does the cable length of the power adapter affect the charging power?

In the era when there was no fast charging before, the charging voltage was only 5V. The length of the wire caused a difference in the internal resistance of the wire, which means that there will be more or less loss of voltage transmission, which in turn affects the charging power, but now fast charging has been It is popularized in electronic equipment, so will the length of the power adapter wire affect the charging power?

Some websites have conducted professional tests on this. The first wire is most of the wire attached to the package of the mobile Power Supply, and the length is about 51cm; the second wire is about 117cm, which is also currently in the hands of most users. The length specification; the third paragraph takes 1.5m long wire. Under the premise of the same 45W Power Adapter, the charging power of the mobile phone was tested by using the same material and different lengths of charging cables and found that the charging power did not change. The final test data of the three charging cables are 45W.

This should have been obvious in the above charging test, whether it is a 51cm short line, a 117cm conventional model or a 154cm extended model, there will be no difference in the power transmission of the device. Therefore, when going out to use mobile power to charge mobile phones, short-line is more suitable, and the 154cm extension is more suitable for home use, not restricted by the wire, use it as you want, choose according to your needs. Length of wire.
