They may not meet Apple’s stringent safety and quality standards, leading to potential damage to your MacBook Pro’s battery, charging port, or internal components. I’ve personally seen devices suffer from unreliable power delivery due to counterfeit chargers.
Counterfeit chargers can also be a fire hazard. They often lack proper insulation, surge protection, and overheating safeguards. A genuine 85W MacBook Pro charger from Apple is designed to work seamlessly with your device, ensuring optimal charging performance and protecting your investment. Investing in authenticity is investing in peace of mind and device longevity.
When to Consider a Third-Party 85W Charger: Quality and Compatibility
While I strongly advocate for genuine Apple chargers, the market for third-party accessories has evolved. Some reputable brands now offer high-quality USB-C chargers that are compatible with MacBooks and can deliver the necessary 85W power. These can be a viable option if you need a spare or a more portable solution.
When considering a third-party option, look for chargers that explicitly state compatibility with your specific MacBook Pro model and wattage requirement. Check for certifications like UL, CE, or FCC, which indicate that the charger has met safety standards. Always read reviews from other users, paying attention to comments regarding charging speed, heat, and long-term reliability.
Key Features to Look for in an 85W MacBook Pro Charger
Beyond the wattage and connector type, several features can enhance your charging experience. GaN (Gallium Nitride) technology is a significant advancement, allowing for smaller, more efficient, and cooler-running chargers. If you opt for a USB-C charger, GaN technology is a definite plus.
Look for chargers with built-in surge protection and overcurrent protection to safeguard your MacBook Pro. Some chargers also offer multiple ports, allowing you to charge other devices simultaneously, which can be incredibly convenient for travelers or those with multiple gadgets. The length and flexibility of the cable can also be important considerations for daily use.
Maintaining Your 85W MacBook Pro Charger for Longevity
Proper care can significantly extend the lifespan of your 85W MacBook Pro charger. Avoid bending the cable sharply, especially near the connector, as this is a common point of failure. When unplugging, pull from the connector itself rather than yanking on the cable. It’s also wise to keep the charger and its cables away from liquids and extreme temperatures.
Regularly inspect the cable and connector for any signs of fraying, cracking, or damage. If you notice any wear and tear, it’s best to replace the charger immediately to prevent further damage or safety hazards. Keeping the charging port on your MacBook Pro clean also ensures a secure connection and prevents charging issues.
Troubleshooting Common 85W MacBook Pro Charger Issues
Encountering charging problems can be frustrating. If your 85W MacBook Pro charger isn’t working, the first step is to check all connections – ensure the cable is securely plugged into both the charger brick and your MacBook Pro. Try using a different wall outlet to rule out an issue with the power source. If your charger has a detachable wall plug, ensure it’s firmly seated in the adapter.
If you’re using a MagSafe charger, check for any debris or obstructions on the magnetic connector. A gentle cleaning with a dry, soft cloth can often resolve connection issues. For USB-C chargers, try a different USB-C cable and port on your MacBook Pro if available. Sometimes, a simple system restart of your MacBook Pro can also help resolve software-related charging glitches. If the problem persists, it might be time to consider a replacement.
