Product Description
This connection cable connects a standard USB-A port to a 4.0/1.7 mm barrel plug. The 80 cm length allows flexible placement of the powered devices around the USB power source without requiring extension cables.
The barrel plug, with an inner diameter of 1.7 mm and an outer diameter of 4.0 mm, is a widely used standard for portable devices and affordable electronic modules. The cable is intended solely for power supply; common components such as small LED lights, fans, or sensor microcontrollers can be powered through it.
The cable cross-section supports operating currents of up to approximately 2 A without any significant voltage drops along the wires; for applications with considerably higher current requirements, the voltage loss increases noticeably. The black PVC material reduces electromagnetic interference affecting other devices.
The cable is used, for example, with portable Raspberry Pi projects, Arduino-based sensor networks, USB-powered laboratory fans, and prototypes with an external power supply module. It is important that the connected device is actually designed for the USB rated voltage of 5 V and that the required current is provided by the USB host or an active USB hub.
Safety Information
The cable is intended exclusively for building prototypes and for testing and development purposes. It must not be integrated into household electrical circuits or professional installations. If you are unsure about the correct power supply for the target device, consult a qualified electrician before commissioning.
