Power supplies and chargers are essential for many small devices and appliances at home. Problems often present as complete device failure, intermittent power, or visible cord damage. Many basic faults can be diagnosed and repaired with attention, patience, and an understanding of safety guidelines. Focus on simple steps, use the right tools, and respect the hazards of working with mains and high-voltage circuits. With careful inspection and appropriate handling, household users can resolve the most common issues.

Diagnosing Faulty Power Adapters

When a device stops charging or fails to power on, the power supply or adapter is often at fault. Begin diagnosis by confirming that the outlet works. Test the device with another compatible adapter if available. Visual inspection is also valuable—look for burn marks, swollen areas, or odor from the supply. Unplug the adapter before handling.

Power supplies can sometimes show external clues hinting at internal failure, like loose parts inside the housing or obvious melting. Be wary of continuing use if physical or thermal damage is visible, as unsafe adapters may pose a fire risk. Guides covering general safety advice for dealing with adapters can be found at Power Supply Safety Standards and Precautions.

Checking Power Cords for Damage

Power cords often break at stress points. Inspect along the entire length, especially near the ends, for any exposed wires, kinks, cuts, or fraying insulation. Damage to the cord can cause short circuits or unreliable charging.

To check, gently flex the cord while the adapter is unplugged. Cracks or breaks that reveal copper should be the focus of immediate repair or replacement. Do not tape over damaged wires as a permanent fix. Quality replacement cords are widely available online and offer a more reliable solution for continued use.

Repairing or Replacing Plugs and Fuses

If the adapter has a replaceable plug or fuse—common in many European-style plugs—inspect these components first. A blown fuse often leaves visible separation inside the glass, or dark deposits can be seen. Replace with the same rating as marked on the original component.

When replacing plugs, select units suited for the current and voltage of the device. Connect colored wires to the same positions as the old plug—matching live, neutral, and ground. Tighten terminals securely, avoiding loose connections. Use only approved replacements.

Testing Power Delivery

Once basic repairs or replacements are completed, test the adapter. Reconnect the cord securely; plug into a known working outlet. If you own a multimeter, measure the output voltage at the adapter’s plug and compare with specifications shown on the unit label. The voltage should fall within 5-10% of the rating.

Lightweight test devices—such as simple LED USB testers—also show if power is delivered to the cable. If readings fall outside expected ranges, further repair should stop. Inconsistent results or sparking during tests suggest deeper internal faults, which should not be handled without advanced knowledge.
