What this adapter does

The Plugable USB-MC1 converts a standard USB Type A data port into a charge-only port that delivers up to 1 A of current. It suits anyone who needs to power a phone, tablet or other mobile device from a laptop, hub or public charger without enabling data transfer.

Installation and common issues

Plug the male Type A end into the host port and connect your device's cable to the female Type A socket; no drivers or configuration are required. The only limitation is the 1 A current ceiling, so devices that need higher amperage will charge slowly or not at all.

Behaviour under sustained load

The adapter passes a steady 5 V at up to 1 A for as long as the host port can supply it, with no thermal throttling or protocol negotiation to interrupt the flow. Because the data pins are physically disconnected, the charge rate stays constant regardless of how long the session lasts.

Questions about this item

How can I confirm the Plugable USB-MC1 is blocking data and only passing 1 A of power after I plug it in?

The adapter has no status LED. You verify it is working by connecting a device — if the device shows it is charging but never appears in file explorer or device manager, the data pins are successfully isolated and the 1 A charge limit is active.

What comes with the USB-MC1 and is anything else required to use it?

The package contains only the black USB-A male to USB-A female adapter. No cable, power supply or driver disc is included; you simply insert it between your existing USB-A cable and the host port.

Are there different current ratings or connector versions of the USB-MC1 to choose from?

This model is offered only as a 1 A charge-only adapter with USB-A male to USB-A female connectors. No higher-amperage or alternative-connector variants exist under the USB-MC1 part number.
