Vszerda USB Male to DC 5.5 x 2.1mm Power Cable 100cm

Power from any USB port

This Vszerda cable draws 5 V DC from a standard USB Type-A socket and delivers it through a 5.5 mm outer-diameter barrel plug with a 2.1 mm centre pin. The 100 cm length gives enough reach for desk or bench use without excess slack. It is built for small electronics that rely on a centre-positive barrel jack for power input. No driver or configuration is required; the connection is purely passive.

Suits low-power barrel-jack gear

Makers, hobbyists and technicians powering development boards, portable speakers, LED strips or similar 5 V devices will find this a tidy alternative to a dedicated wall adapter. It cannot supply more current than the host USB port allows, so equipment that needs higher amperage or voltages other than 5 V must look elsewhere. Devices with a different barrel size or polarity are also incompatible.

Integrates into a USB-powered setup

Plug the Type-A end into any computer, power bank or USB charger to free the device from a mains outlet. The barrel end mates directly with the target unit’s 5.5 x 2.1 mm jack, eliminating the need for a separate AC adapter and its cable. Ensure the host port can deliver the current your device draws; the cable itself adds no regulation or boost circuitry.
