Can I Charge My iPhone with MacBook Charger? Know the Risks!

As you may already know, Apple no longer provides additional accessories like power adapters or earphones with their newer iPhone models. So, if you plan on buying an iPhone 12 or later, you won’t get a power adapter in the box.

However, if you don’t want to buy a separate charger for the iPhone, you can use a MacBook charger instead. Apple now allows charging an iPhone with a MacBook-C charger without any risks.

But there are certain things that you should know and be concerned about. So, the longest answer to your question is below.

Is It Safe to Use a MacBook Charger for an iPhone?

Yes, it is safe to use a MacBook charger for an iPhone. You can simply connect the USB-C to the lightning cable (which came with your iPhone) to your MacBook adapter, plug it into a wall outlet, and let it charge.

There are certain reasons why you can do it without any risk.


Apple has officially approved that iOS devices are compatible with all MacBook USB-C power adapters. Because iPhones come with a USB-C-to-lightning cable that is only compatible with USB-C power adapters.

Optimized Battery Charging Technology

iPhone 13 or above are designed with Optimized Battery Charging technology. It improves the battery’s health and protects it from wear.

When charging, the battery on your iPhone gets a little bit warm, which can reduce the battery’s lifespan.

So, if you enable the optimized battery charging technology on your iOS, the iPhone will delay or stop charging after it reaches 80%. Your iPhone will also stop charging once it is charged completely.

Optimized Battery Charging Technology 

In this way, when you charge an iPhone with a MacBook or iPad charger, the phone won’t get overcharged or overloaded because of this technology.

iPhones are equipped with voltage regulators. Apple uses this technology to regulate the charging within the device itself, regardless of the input voltage.

This technology comes equipped with an in-built voltage regulator that examines the battery’s voltage and temperature while charging. The controller monitors these data to regulate the charge current added to the battery.

Thus, an iPhone will only draw the required amount of current from the MacBook charger. So, it’s safe for your iPhone to charge with a MacBook adapter.
