Why Do MacBook Chargers Stop Working?

MacBook chargers are vital accessories that ensure your laptop remains powered and functional. However, they can sometimes stop working unexpectedly, causing significant inconvenience. Understanding why macbook charger stop working can help you troubleshoot issues and find reliable replacements.

Understanding the Causes and Finding Reliable Solutions

The Anker 737 Charger is a cutting-edge charging solution that offers superior performance and reliability. With advanced technology and robust safety features, it is designed to provide efficient and consistent power to your MacBook. As we delve into the reasons why MacBook chargers fail, we’ll also highlight how the Anker 737 Charger can serve as an excellent replacement.

  1. Wear and Tear Over Time

One of the most common reasons MacBook chargers stop working is due to wear and tear. Over time, the cables and connectors can become frayed or damaged from regular use. This can lead to poor connectivity and, eventually, a non-functional charger. The constant bending and twisting of the cable can cause the internal wires to break, especially near the ends. Regularly inspecting your charger for signs of wear and tear can help you identify issues early and prevent sudden failures. A frayed cable or damaged connector can sometimes be temporarily fixed with electrical tape, but this is not a long-term solution and can pose safety risks. Investing in a high-quality charger like the Anker 737 can provide greater durability and longevity. The Anker 737 Charger is designed with robust materials that withstand daily wear and tear, ensuring a longer lifespan and reliable performance.

  1. Internal Component Failure

Chargers are composed of various internal components, including transformers, capacitors, and circuits. These components can fail due to manufacturing defects, electrical surges, or simply aging. When internal components fail, the charger can no longer convert and deliver power efficiently. For example, a faulty capacitor can cause the charger to stop working altogether. These internal failures can be challenging to diagnose and are often not repairable without specialized tools and knowledge.

  1. Overheating Issues

Overheating is another common cause of charger failure. Chargers can overheat due to poor ventilation, high ambient temperatures, or overuse. Excessive heat can damage internal components and reduce the lifespan of the charger. This is particularly a problem if you use your charger in hot environments or if it is covered while in use, preventing proper heat dissipation. To prevent overheating, ensure your charger has adequate ventilation and avoid using it in excessively hot conditions. 

  1. Power Surges and Electrical Spikes

Power surges and electrical spikes can occur due to lightning strikes, power outages, or faulty wiring. These sudden increases in voltage can damage the delicate components inside your charger, rendering it non-functional. Even minor surges can accumulate over time and degrade the charger’s internal components, leading to eventual failure. Using surge protectors can help safeguard your charger from electrical spikes. Additionally, choosing a charger with built-in protection against power surges, like the Anker 737, can offer an extra layer of security. 

  1. Poor Quality or Counterfeit Chargers

Using poor quality or counterfeit chargers can lead to frequent failures and pose significant safety risks. These chargers often lack the necessary safety certifications and use substandard materials, which can result in overheating, short circuits, and other issues. Counterfeit chargers may look identical to genuine ones but often cut corners in critical areas, compromising their safety and performance.


Understanding why MacBook chargers stop working can help you prevent and address issues effectively. Wear and tear, internal component failure, overheating, power surges, and poor-quality chargers are all common causes of charger failure. By recognizing these issues, you can take steps to protect your charger and ensure consistent power to your MacBook.
