MagSafe与USB-C：哪个更适合给你的MacBook充电？

MagSafe更安全、更简单，但USB-C也有自身的几个优势。

最新的MacBook以搭载苹果巧妙的充电方案而闻名：MagSafe。对一些人来说，这是一项决定买或不买的关键特性。这也不奇怪——这种充电器通过磁力吸附，如果线缆被猛力拉扯，比如被绊到，就会自动断开。但苹果笔记本电脑也可以通过USB-C充电，而USB-C已成为行业标准。虽然你不能同时使用两者，但根据你某一时刻的需求，它们都可以是很好的充电选择。

虽然名字相同，但不要把MacBook的充电技术与iPhone的MagSafe混为一谈，后者是一种不同的技术。iPhone的MagSafe基于Qi标准，而MacBook的MagSafe使用的是专有且小得多的接口。不过，理念是一样的：通过磁力吸附充电器，而不是插入标准USB接口。

MacBook上的MagSafe也经历了几次迭代，目前使用的是MagSafe 3。每一代的基本用途相同，但不同的物理尺寸和功率容量意味着它们并不互相兼容。

MagSafe与USB-C的区别

使用MagSafe或USB-C为MacBook充电各有利弊。对MagSafe来说，最大的优点显而易见：如果线缆成了障碍物，你的笔记本电脑会安然无恙。如果有人绊到线缆，或者你不小心拉得太猛，大概率它只会直接脱落，而不会把你的MacBook一起拽下来。

另一方面，USB-C是一种标准接口。你必须把它插入笔记本电脑上正确的端口。如果发生意外，你的Mac很有可能会被线缆带着一起摔到地上。

但充电功率方面也有重要差异。MagSafe线缆是为更快的充电速度设计的。如果你用的是2021款MacBook Pro、2022款MacBook Air或更新机型，MagSafe可以以最高140W为你的Mac充电。当然，前提是你有合适的电源适配器。苹果售卖一款99美元的适配器，搭配MagSafe线缆即可实现快充。我们说的是仅30分钟就能充到50%，这已经相当快了。

USB-C则是另一回事。虽然理论上有些线缆可以传输更高的瓦数，但大多数线缆并非如此。USB-C的标准功率是60W，只有MagSafe所能提供的一半。有些特殊线缆可提供最高100W或240W的功率——苹果甚至售卖一款240W的USB-C线缆。如果你追求快充，在购买新线缆之前，这一点需要牢记。

USB-C最适合的使用场景

如前所述，大多数情况下MagSafe都是最佳选择。它在物理上更安全，支持快充，还能让你的USB-C端口空出来连接其他配件。它也简单得多——你不必担心复杂的充电标准和规格。直接用苹果的组合，就可以轻松搞定。

但USB-C也能提供一些便利。最显著的一点是一根线缆搞定一切。这让出行方便得多，因为你不必在背包里塞一堆乱七八糟的线缆。一个快速的USB-C充电器可以为你的Mac、iPhone、iPad以及其他任何带USB-C接口的设备供电。MagSafe只适用于Mac。

此外，如果你有2023年11月之后发布的MacBook Pro，还有一个额外好处：这些机型可以通过USB-C以最高240W充电。你需要合适的线缆和电源适配器，但如果你在意超快充电，这仍然是USB-C的又一个优势。归根结底，还是要选择最适合你需求的方式；每种线缆各备一根，就能根据需要随时替换使用。

MagSafe vs. USB-C: Which is better for charging your MacBook?
MagSafe is safer and simpler, but USB-C has a few advantages of its own.
The latest MacBooks are known for featuring Apple's clever charging solution: MagSafe. It's one of those features that's a make-or-break factor for some people. And it's no wonder — these chargers attach magnetically and disconnect if the cable is pulled sharply, like when tripping over it. But Apple laptops can also be charged via USB-C, which has become an industry standard. While you can't use both at the same time, they can both be great charging options depending on what you need at a given moment.
While it has the same name, don't confuse the MacBook's charging tech with the iPhone's MagSafe, which is a different technology. While the iPhone's MagSafe is based on the Qi standard, the MacBook's MagSafe uses a proprietary — and much smaller — connector. Still, the idea is the same: magnetically attaching a charger versus plugging in a standard USB connector.
MagSafe on MacBooks has also gone through a few iterations, with MagSafe 3 being the current one. Each generation has the same fundamental purpose, though different physical sizes and power capacities means they aren't cross-compatible.
The differences between MagSafe and USB-C
There are pros and cons to using either MagSafe or USB-C to charge your MacBook. For MagSafe, the biggest pro is obvious: your laptop is kept safe if the cable becomes an obstacle. If someone trips over the cable or you accidentally pull on it too hard, chances are that it will simply come unplugged. It won't pull your MacBook down with it.
USB-C, on the other hand, is a standard connector. You have to insert it into the right port on your laptop. And if an accident happens, there's a good chance your Mac will be pulled along with the cable and hit the floor.
But there are also important differences in charging power. The MagSafe cable is designed for faster charging. If you have a 2021 MacBook Pro, a 2022 MacBook Air or later, MagSafe can charge your Mac at up to 140W. That is, of course, if you have the right power adapter. Apple sells a $99 adapter that pairs with the MagSafe cable to enable fast charging. We're talking about a 50 percent charge in just 30 minutes, which is quite fast.
USB-C is a different story. While there are cables that can deliver even higher wattages in theory, that's not the case for most of them. The standard for USB-C is 60W of power, which is half of what MagSafe can deliver. There are special cables that deliver up to 100W or 240W of power — Apple even sells a 240W USB-C cable. This is something you need to keep in mind before buying a new cable if you're looking for fast charging.
When USB-C works best
As we've seen, MagSafe is the best choice in most cases. It's physically safer, supports fast charging and keeps your USB-C ports free for other accessories. It's also much easier — you don't have to worry about complicated charging standards and specs. Just use the Apple combo, and you're good to go.
But USB-C can offer some conveniences, too. The most notable is a single cable handling everything. This makes traveling much easier, since you don't need a mess of cables in your backpack. A fast USB-C charger can power your Mac, iPhone, iPad and anything else with USB-C. MagSafe is for Macs only.
Plus, if you have a MacBook Pro released after November 2023, there's an extra treat: these can charge at up to 240W via USB-C. You'll need the right cable and power adapter, but it's still another benefit of USB-C, if ultra-fast charging is something you care about. It really comes down to choosing what works best for your needs; keeping one of each cable around lets you swap them as needed.
