30 cm USB-C power extension for Raspberry Pi 4B

This 30 cm USB-C male-to-female cable adds an inline power switch to the Raspberry Pi 4B supply. It carries up to 5 V at 4 A and is built with 26 tin-coated copper cores wrapped in PVC. The switch lets you cut power without repeatedly plugging and unplugging the connector.

Installation and common issues

Plug the male end into the existing power supply and the female end into the Pi 4B, then use the toggle to turn the board on or off. The cable only delivers power; it does not pass data or support fast-charging protocols, so it cannot be used for file transfers or high-current quick-charge devices. The 30 cm length offers limited reach, so verify the routing path before fitting.

What to check before ordering

Confirm that your Raspberry Pi 4B power supply uses a USB-C connector rated for 5 V 4 A operation. Ensure the enclosure or desk layout can accommodate the extra 30 cm of cable and the switch housing. Remember that this cord is strictly for power delivery and will not work for data links or fast-charging applications.

Questions about this item

How can I confirm the cable is delivering 5V 4A to my Raspberry Pi 4B after connecting it?

The built-in ON/OFF switch lets you power the board on and off without unplugging; when the switch is on and the Pi boots normally, the cable is working as intended.

What comes in the box and do I need to buy a separate power adapter?

The package includes one 30cm Type-C male-to-female cable with an integrated switch; a 5V 4A USB-C power supply must be provided separately.

Which cable length should I choose for a tidy Raspberry Pi 4B setup?

This model is offered in a single 30cm (11.8in) length, designed to keep the power connection short and neat.
