You've been there before. You're sitting at your desk, working away on your MacBook, when suddenly, you notice that your iPhone's battery is almost dead. As you frantically search for your iPhone charger, a thought crosses your mind: "Can I use my Mac charger to charge my iPhone?" In this article, we'll uncover the truth behind this burning question and find out whether it's safe and efficient to use your Mac charger for your iPhone. Grab a cup of coffee and join me on this journey to put an end to this myth once and for all!
Before we dive into whether you can use your Mac charger to charge your iPhone, let's take a closer look at the chargers themselves. Apple chargers have come a long way, with USB-C now being the standard for both MacBook and iPhone chargers. However, there's a key difference between the two: the power output.
MacBooks typically require a charger with a power output ranging from 29W to 96W, depending on the model. On the other hand, iPhones generally come with a 5W or 20W charger, depending on whether you have an older or newer model. With this significant difference in power output, one might wonder if it's safe to use a higher-powered Mac charger on an iPhone.
Now that we know the difference in power output between Mac and iPhone chargers, let's dive into the science behind charging. Every charger has a specific voltage and current output, and these two factors determine the power output. The good news is that both Mac and iPhone chargers use the USB Power Delivery (USB-PD) standard, which means that they can negotiate the required power output with the device they're charging.
For example, if you plug your iPhone into a 61W Mac charger, the charger will recognize that it's connected to an iPhone and adjust the power output accordingly. In other words, your iPhone will only draw the power it needs, even when connected to a higher-powered Mac charger.
To give you a better understanding, let's take a look at a real-life example. Imagine you have a MacBook Pro with a 61W charger and an iPhone 12. If you were to connect your iPhone 12 to the MacBook Pro charger, the charger would recognize the iPhone and lower the power output to 20W, which is the maximum charging rate for the iPhone 12. In this case, you can safely use your Mac charger to charge your iPhone without any risk of damage.

Yes, as long as the device you want to charge uses USB-C and supports USB-PD technology, you can safely use your Mac charger to charge it. This includes iPads, Android smartphones, and even some portable gaming consoles.
Apple-certified chargers usually have an "Apple Certified" or "Made for iPhone/iPad" label on the packaging or the charger itself. Additionally, you can check the list of Apple-certified accessories on the official Apple website.
While you can technically plug your MacBook into an iPhone charger, the charging process will be extremely slow and inefficient due to the lower power output of the iPhone charger. It's not recommended to use an iPhone charger for your MacBook.
No, using a Mac charger to charge your iPhone will not have a negative impact on your battery life. The USB-PD technology ensures that your iPhone only draws the necessary power, preventing any overcharging or battery degradation.
The short answer is: yes, you can use your Mac charger to charge your iPhone, provided that both devices use USB-C and USB-PD technology. While it may not be the most practical solution, especially if you need to charge your Mac and iPhone simultaneously, it's a safe and efficient method in a pinch.
However, it's important to note that using a non-Apple charger or a low-quality third-party charger can pose risks to your devices. To ensure the safety of your iPhone and MacBook, always use Apple-certified chargers and accessories.
In conclusion, while it might not be the most convenient option, using your Mac charger to charge your iPhone is a safe and viable solution when you're in a bind. So, the next time you find yourself with a dying iPhone and no iPhone charger in sight, rest assured that your trusty Mac charger will come to the rescue!
