USB-C Female to DC 7.9x5.0mm Male Adapter

This 100W adapter converts a USB-C power source to a 7.9x5.0mm DC barrel plug. It suits users who need to charge compatible laptops or devices from a USB-C PD charger or power bank. The compact form factor makes it a practical accessory for travel or desk use. Current rating reaches 5A for supported power profiles.

Zinc alloy housing with 33 x 29 x 7mm dimensions

The zinc alloy shell provides a rigid, durable feel while keeping the adapter light and pocketable. A USB-C female port accepts the charging cable, and the fixed 7.9x5.0mm male tip plugs directly into the device. No extra cables or detachable tips are required, so the connection stays secure during daily carry and frequent insertion cycles.

Replaces bulky proprietary AC bricks for USB-C PD

Users carrying a dedicated barrel-tip charger can switch to a single USB-C PD power supply for multiple devices. The jump is worthwhile when the laptop or device negotiates 100W over USB-C and the barrel diameter matches 7.9x5.0mm. It does not suit devices needing a different barrel size, higher current, or voltage profiles beyond the adapter's fixed specification.
