How to Fix a USB Socket Not Charging

Overview

A USB socket that does not charge devices can be frustrating. This guide covers diagnosing and fixing the issue.

Step-by-Step Fix

1. Begin by testing the USB socket with a different, known-working device and a different charging cable; this helps confirm if the problem lies with the socket itself or potentially with your original device or cable.
2. Carefully inspect the USB port itself for any visible debris such as dust, fluff, or bent pins that might be obstructing the connection; use a small, non-conductive object like a wooden toothpick or a plastic spudger to gently clear any blockages.
3. For integrated wall sockets, ensure the mains power to the socket is switched off at the consumer unit (fuse box) before proceeding, then carefully remove the faceplate and visually check that all wiring connections are securely in place and not loose or corroded.
4. If you find any loose wiring connections during your inspection, carefully tighten the terminal screws to secure the wires firmly in place; double-check that no bare copper is exposed and that all connections are snug before reattaching the faceplate and restoring power.
5. If, after checking all connections and eliminating other possibilities, the USB socket still fails to charge, it is likely faulty and requires replacement; always switch off the mains power at the consumer unit before attempting to remove and install a new, correctly rated USB socket, following the manufacturer's instructions carefully.
