Electric shavers with a proprietary port

Branded (proprietary)

— "Native" plug or magnetic dock designed specifically for a certain electric shaver. They are valued for stable fixation, neat storage — "put down and charging starts" — and often better waterproofing during wet shaving. The downside is the dependency on the original cable or dock: losing or breaking the accessory will complicate replacement while traveling, and universal phone chargers won't suffice. This option is convenient for home use by the sink, where the base also serves as a stand.
