Is there a problem with the extension cord of Huawei q2s power cord?

Huawei q2s power cord expansion is no problem.

It doesn't matter, the charging cable is all optical fiber, and the transmission speed is the same.

If the extension cord at the back end is lengthened, it will have an impact. Because the transmission power itself is low, if an extension cord is added, the output power will be lost, which will affect the charging, while the front-end voltage of 220v is large, even if there is loss, it will have little impact on the input power!
