Quick Answer: MacBook chargers can turn yellow due to exposure to sunlight, heat, or dirt accumulation over time. However, the discoloration does not affect the functionality of the charger.
Have you ever noticed that your MacBook charger has turned yellow? It may have left you wondering why this happens and if it could possibly be a cause for concern. Fear not, because in this article, we will delve into the reasons behind this phenomenon and put your worries to rest.
One of the primary causes of the yellowing of MacBook chargers is prolonged exposure to sunlight. Over time, the UV rays in sunlight can cause the plastic casing of the charger to change color. Additionally, heat can also play a role in this discoloration, especially if the charger is often left plugged into an outlet or used for extended periods.
Furthermore, dust and dirt accumulation can contribute to the yellowing of the charger. As these particles settle on the surface of the charger, they can alter its appearance. However, it is important to note that the yellowing does not affect the functionality of the charger.
So, the next time you notice your MacBook charger sporting a yellowish hue, you can rest assured that it is merely a cosmetic change and not something to worry about.
Why Do MacBook Chargers Turn Yellow?
Have you ever noticed that over time, your MacBook charger starts to turn yellow? It’s a common phenomenon that many MacBook users have experienced. While it may be concerning at first, there’s usually no need to worry. In this article, we will explore the reasons behind why MacBook chargers turn yellow and whether it indicates a potential problem. So, let’s dive in and uncover the mystery!
1. Natural Oxidation Process
The most common reason for the yellowing of MacBook chargers is the natural oxidation process. The charger’s outer shell is made of white plastic, and over time, exposure to air and light can cause it to yellow. This process is similar to how white paint can fade or turn yellow when exposed to sunlight for extended periods.
The reaction starts with the plastic’s exposure to ultraviolet (UV) light, which breaks down the chemical bonds in the material. Over time, this leads to changes in the plastic’s physical appearance, causing it to become yellowish.
1.1 Factors That Accelerate Oxidation
Several factors can accelerate the oxidation process and make the charger turn yellow faster. These factors include:
- Exposure to sunlight: Leaving your charger in direct sunlight for prolonged periods can speed up the yellowing process.
- Heat: High temperatures can cause the plastic to break down more quickly, accelerating the yellowing effect.
- Humidity: A humid environment can contribute to the oxidation process, especially if the charger is stored in a damp area.
- Chemical exposure: Certain chemicals, such as hydrogen peroxide or bleach, can react with the plastic, causing discoloration.
It’s essential to note that while these factors can accelerate the process, even with proper care and storage, your MacBook charger may still turn yellow over time due to natural oxidation.
2. Material Composition
Another factor that plays a role in the yellowing of MacBook chargers is the material composition. The outer shell of the charger is made from polycarbonate, a type of plastic known for its durability and impact resistance. However, polycarbonate can be susceptible to discoloration and yellowing over time.
The yellowing effect is more noticeable in MacBook chargers compared to other Apple products because of the specific type of polycarbonate used. This material is a blend of polycarbonate and acrylonitrile-butadiene-styrene (ABS) plastic. While ABS provides additional strength to the charger’s shell, it is more prone to yellowing compared to pure polycarbonate.
3. Dirt and Stains
Aside from oxidation and material composition, dirt and stains can also contribute to the yellowing of MacBook chargers. The exterior of the charger can accumulate dust, oils from hands, and other substances that may cause discoloration. Regular usage of the charger exposes it to various environments, increasing the likelihood of dirt and stains adhering to its surface.
3.1. Prevention and Cleaning
To prevent dirt and stains from accumulating on your MacBook charger, consider the following tips:
- Keep the charger away from dusty or dirty areas as much as possible.
- Avoid touching the charger with dirty or greasy hands.
- Periodically wipe the charger’s surface using a soft, damp cloth to remove any dirt or stains.
By practicing regular cleaning and maintenance, you can minimize the yellowing caused by external contaminants.
4. Does Yellowing Indicate a Problem?
The yellowing of your MacBook charger is primarily a cosmetic issue and does not necessarily indicate a problem with its functionality. As long as your charger is still working properly and providing the necessary power to your MacBook, there’s typically no need for concern.
However, if your charger shows signs of physical damage, such as frayed cables or exposed wires, it’s crucial to replace it promptly. Damaged chargers can pose a safety risk and may result in electrical hazards or even fire.
4.1. Warranty Coverage
If you’re concerned about the yellowing of your MacBook charger and believe it may be a defect, it’s worth checking if the charger is still covered under Apple’s warranty. Apple’s warranty covers manufacturing defects and malfunctions, but it generally does not include cosmetic issues such as yellowing. Nevertheless, it’s always best to contact Apple Support for assistance and clarification regarding your specific case.
5. Maintaining the Charger’s Appearance
While the yellowing of MacBook chargers is inevitable over time, there are steps you can take to maintain the charger’s appearance and prolong its lifespan:
- Store the charger in a cool, dry place when not in use.
- Avoid leaving the charger plugged in and connected to your MacBook for extended periods.
- Consider using protective cases or sleeves for your charger to minimize exposure to sunlight and other environmental factors.
By following these tips, you can slow down the yellowing process and keep your MacBook charger looking cleaner for longer.
In conclusion, the yellowing of MacBook chargers is a result of the natural oxidation process, material composition, and external elements such as dirt and stains. While it may be aesthetically unpleasing, it does not typically affect the charger’s functionality. By understanding the reasons behind this discoloration and taking preventive measures, you can ensure your MacBook charger remains in good condition for an extended period.

Frequently Asked Questions
Why do MacBook chargers turn yellow?
The yellow discoloration observed on MacBook chargers is typically due to a combination of factors, including exposure to sunlight, heat, and prolonged usage.
How does sunlight affect MacBook chargers?
Sunlight contains ultraviolet (UV) radiation, which can cause the plastic casing of MacBook chargers to yellow over time. The UV rays react with the plastic materials, leading to discoloration.
Can heat cause MacBook chargers to turn yellow?
Yes, excessive heat can contribute to the yellowing of MacBook chargers. The plastic used in their construction is sensitive to high temperatures, and prolonged exposure to heat can cause the material to degrade and change color.
Does extended usage impact the yellowing of MacBook chargers?
Extended usage of MacBook chargers can also contribute to their yellowing. The heat generated during charging, combined with natural oils and dirt transferred from hands, can gradually cause the charger’s exterior to turn yellow.
Are yellowed MacBook chargers still safe to use?
While the yellowing of MacBook chargers may be unsightly, it does not necessarily affect their functionality or safety. However, it is important to regularly inspect the charger for any signs of damage or fraying cables, as these can pose potential risks and should be replaced.
How can I prevent my MacBook charger from turning yellow?
To prevent yellowing, it is advisable to avoid exposing the charger to direct sunlight or extreme heat. Additionally, wiping the charger’s surface with a clean, slightly damp cloth regularly can help remove dirt, oils, and other substances that could contribute to discoloration.
MacBook chargers can turn yellow due to a combination of factors. One reason is oxidation, which occurs when the metal components of the charger react with air and moisture.
