VENTION USB-A to 3.5mm DC Jack Power Cable (0.5m) - Black

Description

The USB-A to 3.5mm DC Jack power cable from the VENTION brand (length 0.5 metres) is a technical-grade energy transfer cord, specifically configured for electronic repair workshops, diagnostic laboratories, and B2B infrastructure management. Designed exclusively for auxiliary electrical power, this cable allows for diverting and exploiting the DC voltage of a standard USB port (on a PC, powered hub, or wall charger) to power small network or multimedia peripherals without mobilising a bulky dedicated mains power block.

In terms of electronic engineering, this cord provides a purely electrical link (VCC and GND) and does not integrate any pair of lines dedicated to data or audio signals. It extracts the fixed nominal voltage of 5V DC delivered by the source USB-A interface. The output connector is a cylindrical barrel-type jack with a precise external diameter of 3.5 mm, configured according to the universal standard polarity of centre positive (+). The internal conductors are cast in high-purity copper with low ohmic resistance, ensuring a stable amperage flow and limiting line voltage drops, a critical factor during workshop component testing phases.

Its length of 50 centimetres makes it an ideal accessory for the clean arrangement of workbenches and test stations, eliminating superfluous cable loops prone to accidents or the induction of electromagnetic interference. The connector chassis and external sheath are moulded in polyvinyl chloride (PVC) with high dielectric insulation and optimised flexibility, reinforcing the longevity of junction points against repeated pulling and handling.

• Connector Type B: Cylindrical DC Male Jack (External diameter: 3.5 mm)
• Electrical Polarity: Centre Positive (+) / Outer Negative (-)

Workshop Advice & Usage

Be careful not to make a routing error during your maintenance protocols: this cable is a pure power interface and not an auxiliary audio cable; plugging it into a 3.5mm audio jack port will not emit any signal and may damage the input circuit of the device's sound card. Before any connection, use callipers to validate that the female port of the client device measures exactly 3.5 mm in external diameter (and not 2.5 mm or 5.5 mm). Also, check on the device label that the required voltage is strictly 5V DC: applying this cable to equipment requiring 9V or 12V will lead to electrical undersizing and immediate hardware malfunction.
