Hi, please know we have different versions of cables. The Powerline+II is the upgraded version of the Powerline+, and the Powerline II is the upgraded version of the Powerline.
To answer your question, we can only say the Powerline II is newer than the Powerline+. We do not compare the Powerline II with the Powerline+ as they are totally different version. We only compare the Powerline+II with the Powerline+, and compare the Powerline II with the Powerline.
We believe there should be no different about the charging speed between the Powerline II and the Powerline+.
