3 m Micro USB charge and sync cable

This three metre cable connects a standard USB Type A port to a Micro USB device for charging and data transfer. The 24 AWG power conductors are sized to deliver full charging current to phones, tablets and other power hungry mobile equipment. Black PVC jacket and moulded strain reliefs give a durable finish for daily desk or travel use.

Replaces shorter or thinner Micro USB leads

A 30 AWG data pair handles sync traffic while the heavier 24 AWG power pair reduces voltage drop over the longer run. The upgrade is worth it when a short cable cannot reach the device or when a thin cable limits charge speed. It does not suit devices that require USB C or Lightning connectors.

Consistent delivery over the full length

The thicker power wires keep voltage at the device within spec during a complete charge cycle rather than only in a quick top up. Signal integrity on the data pair remains stable for uninterrupted sync sessions. The cable is not designed for high power applications beyond standard Micro USB charging limits.
