USB 2.0 power cable with on-off switch

This USB 2.0 Type-A male-to-female cable carries only DC 5 V power up to 3 A. It is designed for low-power USB-A devices such as desk lamps, small fans, LED light bars and similar accessories. No data lines are present, so it cannot be used for file transfer or device syncing. The integrated push button lets you cut power without unplugging the connector.

Plug in and press the button to start

Insert the male end into any standard USB-A power source and the female end into the device you wish to power. A single press of the built-in switch toggles the supply on or off, reducing physical wear on both ports. Because the cable lacks data conductors, it will not enumerate on a host controller; attempting to use it for data connections simply results in no link. Do not connect it to a USB Power Delivery charger or any high-current host port.

Limited to 5 V 3 A charging with no data capability

The two-core construction supports only DC 5 V at a maximum of 3 A and does not implement any fast-charge negotiation protocol. It cannot power laptops, monitors or other high-draw equipment, nor can it be used with Power Delivery adapters. Buyers who need simultaneous data and power, or higher-voltage charging, must choose a fully wired USB cable instead.
