100W 7.9 x 5.0mm to USB-C Adapter

This adapter connects a device with a 7.9 x 5.0mm barrel port to a USB-C power source. It supports up to 100W power delivery for charging or operation. The 1.7m nylon-braided cable provides flexible placement. It is built for plug-and-play use without drivers.

Suits barrel-to-USB-C charging, not data

Users needing to power a 7.9 x 5.0mm device from a USB-C charger will find this fit for purpose. It does not carry data signals, so it cannot link peripherals or drives. Buyers who need a second connector type or a different barrel diameter should look elsewhere.

100W headroom for most laptops and gear

The 100W rating handles most ultrabooks, tablets and similar hardware comfortably. It runs out when a device demands more than 100W or uses a proprietary charging protocol not covered by standard USB-C Power Delivery. The 1.7m length gives desk reach without excess slack.
