Charging a MacBook Pro via an iPhone Charger: Understanding the Time and Efficiency

When it comes to charging your MacBook Pro, using an iPhone charger can be a convenient but less efficient solution. This article will explore the reasons why charging from an iPhone charger takes significantly longer than using a MacBook Pro charger, depending on various factors such as the state of charge and the level of activity on the MacBook Pro. Let's dive into the details to help you understand the implications of this practice.

The Impact of Using an iPhone Charger

When you attempt to charge your MacBook Pro using an iPhone charger, you may notice that the process is considerably slower compared to using the original charger. This is because iPhone chargers are designed to provide optimal power output for devices that require less power input, making them less suitable for charging a more power-hungry device like a MacBook Pro.

Time Differences

John, an expert in the field of electronic charging, has noted that charging a MacBook Pro using an iPhone charger will inevitably take longer. Specifically, it will take much longer than the built-in charger, possibly taking weeks under certain conditions, and it might not even complete the charging process at all if the MacBook Pro is in use. This is due to the fact that the iPhone charger will not be able to deliver the necessary power to keep up with the higher drain of the MacBook Pro.

State of Charge Matters

The state of charge of both the MacBook Pro and the iPhone charger plays a significant role in the charging efficiency. If the MacBook Pro is completely powered down, an iPhone charger might theoretically charge it, albeit much more slowly. However, if the MacBook Pro is in use, the chiropractor would not be able to keep up with the battery drain, leading to a significantly slower charging process or even no charging at all.

The Technical Breakdown

iPhone chargers are typically designed to provide a maximum power output of around 18W (for newer chargers) and 5W for older models. On the other hand, the MacBook Pro requires significantly more power, with models like the 2020 and newer requiring 61W or 87W chargers. This large disparity in power requirements means that an iPhone charger will not be able to supply the necessary current to charge the MacBook Pro at a reasonable speed.

Conclusion and Best Practices

In conclusion, using an iPhone charger to charge your MacBook Pro is not recommended, especially if the laptop is in use. The charging process will be significantly slower, possibly taking weeks, and in some cases, it might not charge at all. To ensure optimal battery performance and minimize charging times, it is advisable to use a MacBook Pro-specific charger that provides the necessary power output.
