Energy requirements, design, function… why are Mac chargers so big? Here are the secrets behind the imposing appearance of MacBook chargers.
You would have to be blind not to realize it. Indeed, when you unbox your MacBook, it’s hard to miss the size of its charger. But why such a disparity between the Mac charger and those of the iPhone or iPad?
Before going into the details, it is essential to understand the technical considerations necessary for the proper functioning of each device. Indeed, Apple strives to provide suitable chargers for each device. The aim is to ensure efficient and safe charging.
The power adapted to each device
Let’s start by understanding the specific power needs of the iPhone and iPad. Indeed, the iPhone is designed to work with a charger delivering a slower flow of electricity, while the iPad requires more power to supply its larger battery.
Now let’s look at the MacBook. With its high power consumption and massive battery, a simple iPad charger would barely charge its battery. Or even wouldn’t make it. To meet these high energy needs, Apple must provide more powerful chargers, capable of delivering up to 96 watts (or even 140 watts).

The challenges of warmth and design
However, increasing power brings its own set of additional challenges. The increased heat output requires larger metal heat sinks. This is to avoid overheating issues. In addition, the international compatibility of the chargers adds additional components. The Cupertino company must therefore increase their overall size.
That’s why MacBook chargers are so bulky. Their size is closely related to the specific energy needs of each device, the need for fast charging and efficient heat management.
