Hair clippers with a proprietary port

Branded (proprietary)

— proprietary connector of the manufacturer or a docking station designed for a specific model. The advantage of this solution is usually a tighter fit, sometimes better moisture protection, and convenient storage on a stand, especially if the clipper is kept "on the base" and always charged. The drawback is the reliance on the original cable/adapter: if lost or broken, finding a replacement is more challenging and expensive than USB-C or microUSB. Example of usage — a home or salon clipper sits on a docking station, always charged and ready for use, but for a trip, it's essential to remember the "native" charger.
