eForChina 100W USB-C Female to DC 4.8x1.7mm Male Adapter

USB-C to DC 4.8×1.7 mm adapter

This compact adapter converts a USB-C power source into a 4.8 mm by 1.7 mm barrel plug. It delivers up to 100 W at 5 A through a zinc alloy housing that measures 33 by 29 by 7 mm. The female USB-C input accepts standard USB Power Delivery chargers or power banks. The male barrel output fits laptops and devices that use this specific centre-positive connector.

Suits owners of barrel-port laptops who want USB-C

Travellers and minimalists can replace a proprietary brick with a single USB-C GaN charger and this adapter. It is not for devices that require a different barrel diameter, a centre-negative polarity, or more than 100 W of power. Buyers who need simultaneous data transfer or video output should look at a full-featured dock instead. Anyone without a USB-C PD source capable of the required voltage profile will not benefit.

Handles up to 100 W for compatible laptops

The 5 A rating supports most ultraportables and mid-range notebooks that charge over a 4.8 mm barrel jack. Headroom exists for phones, tablets and accessories that draw less current. It runs out when a device demands higher wattage, a different voltage step not offered by the source, or a connector size other than 4.8 mm by 1.7 mm. The tiny form factor leaves no room for extra ports or cables.
