Which Power Supply for iPhone, iPad & MacBook? Watts, USB-C & GaN Explained Simply
Which power adapter do I actually need for my iPhone, iPad, or MacBook?
We hear this question almost daily in our stores. And it's absolutely justified: many new Apple devices now come without a traditional power adapter in the box – at the same time, there's USB-C, fast charging, different wattages, multiport chargers, and GaN technology.
The good news: It's much simpler than it seems at first glance.
We'll explain which power adapter fits which Apple device, how many watts are really useful, why "too many watts" won't harm your device – and why modern compact third-party power adapters are often the more practical choice.
Why do new Apple devices often no longer include a power adapter?
Apple no longer includes a separate power adapter with many current devices. This has been the case for the iPhone for some time now, and with more and more devices, you should consciously plan for the appropriate charger.
One reason for this is sustainability: many users already have power adapters at home, packaging is getting smaller, and unnecessary electronic waste should be avoided.
In addition, there are new legal requirements from the EU: USB-C is the common charging standard for many electronic devices. The goal is for one charger to be able to charge as many devices as possible – from smartphones to tablets to laptops.
For you, this means in everyday life: A good USB-C power adapter can now charge iPhone, iPad, AirPods, and often also MacBook.
USB-C: The common standard for current Apple devices
Almost everything at Apple now runs on USB-C – at least for current devices.
These include, for example:
- iPhone 15, iPhone 16 and iPhone 17 models
- iPad models with USB-C
- MacBook Air, MacBook Pro and the new MacBook Neo
- all current AirPods models
This is practical because you no longer need a separate plug for each device. The only crucial thing is: The power adapter should have enough power.
A good USB-C power adapter can reliably charge multiple Apple devices today
How many watts do I really need?
The wattage simply indicates how much power a power adapter can deliver at most. Depending on the device, different amounts of this power are used.
Important: The device itself decides how much power it draws.
So an iPhone won't break just because you connect it to a 65W or 100W power adapter. It only draws as much power as it needs. This is called USB-C Power Delivery – or USB-C PD for short.
As a simple guide:
- 25–40W: ideal for iPhone, AirPods, smaller iPads and Apple Watch
- 30–45W: ideal for MacBook Neo and many iPads
- 65W: perfect all-rounder for MacBook Air, iPad and iPhone
- 100W: ideal for MacBook Pro, multiple devices simultaneously and power users
Our tip: It's better to choose a high-quality power adapter with some reserve, rather than one that is too weak and constantly operating at its limit.
iPhone 17 and iPhone 17 Pro: How many watts are useful?
A lot has changed with the iPhone in recent years. Current models like the iPhone 17 and especially the iPhone 17 Pro can charge very quickly with a suitable USB-C power adapter.
For many iPhone users, a compact power adapter with around 25W is completely sufficient. Those who want to charge an iPhone 17 or iPhone 17 Pro as quickly as possible are better off with a stronger power adapter – for the iPhone 17 Pro, a 40W power adapter or higher is useful if you want to make the best possible use of the fast charging capability.
For everyday use, this means:
- Charging iPhone overnight: 25W is easily enough
- Fast charging iPhone in between: 40W or more is useful
- Charging iPhone + iPad or AirPods simultaneously: prefer a multiport power adapter
MacBook Neo: small MacBook, small power requirements
The new MacBook Neo is particularly exciting because it works very efficiently. It requires significantly less power than a traditional MacBook Pro.
For many users, a small USB-C power adapter is sufficient. Those who want some reserve or want to charge an iPhone or AirPods at the same time will find a 65W multiport power adapter particularly flexible.
Our simple recommendation:
- MacBook Neo alone: 25W is sufficient in many cases
- MacBook Neo + iPhone: 65W multiport is significantly more practical
- One power adapter for bag, office and travel: compact 65W GaN power adapter
Especially with the MacBook Neo, a good power adapter is not a huge, expensive adapter – but often a small, lightweight USB-C plug.
MacBook Air and MacBook Pro: more power is worthwhile here
For the MacBook Air, we often recommend a 65W power adapter. This provides enough power for everyday use and often has reserves for a second device.
For the MacBook Pro, it depends more on the model and usage. Those who work a lot, render, program, or charge multiple devices simultaneously will be significantly more flexible with 100W.
- MacBook Air: 65W is the perfect sweet spot
- MacBook Pro: 100W is useful if you want power and reserve
- MacBook + iPhone + iPad: Multiport instead of single adapter
What is GaN – and why are these power adapters so practical?
GaN stands for Gallium Nitride. This sounds technical, but it's easy to explain in everyday terms:
GaN power adapters are smaller, lighter, and more efficient than many older chargers.
The advantages:
- more compact design
- less heat generation
- high performance despite small size
- ideal for travel, office, and bag
- often multiple ports in one power adapter
Especially if you use an iPhone, iPad, and MacBook, a good GaN multiport power adapter is often the most elegant solution.
GaN power adapters offer high performance in a very compact design
Apple power adapter or third-party?
Apple, of course, continues to offer its own USB-C power adapters. These are technically high-quality, reliable, and a good choice if you consciously want to stick with original accessories.
In everyday life, however, we often recommend high-quality third-party power adapters because they simply make more sense for many customers:
- often more compact
- usually cheaper
- often multiple ports
- modern GaN technology
- one power adapter for multiple devices
This is not an "Apple is bad" argument – quite the opposite. Apple devices work excellently with high-quality USB-C PD power adapters. The important thing is to pay attention to quality and appropriate performance.
If you still prefer an original Apple power adapter, we naturally also have suitable Apple adapters. For many users, however, a modern multiport power adapter is simply more practical in everyday life.
Our recommendation: which power adapter for which device?
For iPhone, AirPods and smaller iPads
For iPhone, AirPods, and smaller iPads, a compact power adapter with around 25W is usually sufficient. This is ideal for bedside tables, offices, or travel.
Our recommendation:
- Sudio P1 USB-C Power Adapter 25W – compact, simple and ideal for iPhone and iPad
For MacBook Neo, MacBook Air, iPhone and iPad
If you're looking for a power adapter for multiple devices, 65W is the best all-round range.
This gives you great flexibility: charge your MacBook Neo or MacBook Air, then connect your iPhone or AirPods – done.
Our recommendations:
- Tech-Protect 65W Multiport Charger – powerful all-rounder for MacBook Air, MacBook Neo, iPhone and iPad
- Sandberg Dual-Port Charger 65W with Travel Adapter – especially practical for travel
For MacBook Pro, power users and multiple devices simultaneously
Those who want maximum flexibility opt for 100W.
This is particularly practical if you use a MacBook Pro or want to charge multiple devices simultaneously.
Our recommendation:
- Tech-Protect 100W Multiport Fast Charger – ideal for MacBook Pro, iPhone, iPad and desktop setups
Frequent question: Can a stronger power adapter harm my iPhone?
No – as long as it's a high-quality USB-C PD power adapter.
An iPhone doesn't automatically charge at 65W or 100W when connected to a 65W or 100W power adapter. The iPhone itself regulates how much power it can draw.
This means:
- too little wattage: charges slowly or may not be enough for MacBooks
- enough wattage: charges reliably and quickly
- more wattage: provides reserve, but does not cause harm
What's important is not "as many watts as possible," but a good power adapter with appropriate performance.
Our conclusion
The right power adapter makes everyday life much simpler.
For an iPhone, a compact 25W power adapter is often completely sufficient. For MacBook Neo and MacBook Air, a 65W multiport power adapter is particularly practical. For MacBook Pro and multiple devices simultaneously, 100W is worthwhile.
And the most important thing:
More watts will not harm your Apple device – your device will only draw the power it needs.
