How to Use an Apple Watch Charger to Charge Your iPhone 12

Are you trying to use your Apple Watch charger to charge your iPhone? Can you even charge an iPhone with an Apple Watch charger? In this guide, I will discuss whether you can charge your iPhone with your Apple Watch charger in a pinch, and I will also discuss Magsafe Duo compatibility. Let’s get into it.

Understanding MagSafe and Qi Charging for iPhones

iPhones can be charged both with a wired cable and wirelessly. If you are charging an iPhone wirelessly using the MagSafe charger, it will use Apple’s proprietary Magsafe technology to charge. iPhones are also compatible with Qi wireless charging standards, meaning you can use a non-Apple Qi charger to charge your iPhone wirelessly.

Why the Apple Watch Charger Will Not Work for iPhone

So, why can’t the Apple Watch charger charge an iPhone?

The Apple Watch charger was designed to charge the Apple Watch only. In fact, it uses a completely different wireless charging technology designed only for the Apple Watch. Therefore, iPhones are not compatible with it, since they are not compatible with this wireless charging technology.

Therefore, you cannot charge an iPhone with an Apple Watch charger.

Using the MagSafe Duo Charger for iPhone and Watch

What about the MagSafe Duo charger? This dual Apple charger was designed to charge both an iPhone and Apple Watch together, at the same time. It has two spots: one to place the Apple Watch, and one to place your iPhone. It supports both technologies and can charge an iPhone and Apple Watch together.

The Duo charger has since been discontinued as Apple transitioned to Type C charging ports. It is also small, so newer iPhone models (from the iPhone 15 onwards and even the iPhone 14 Pro) might not sit flush on the charger, and it may therefore be difficult to charge them.

The Duo charger was designed to be compatible with the iPhone 12, 13, and 14. These phones (not including the Pro versions) will work with the Duo charger.

Charging iPhone 12 With Standard Apple Chargers

You can use any older standard iPhone charger with the iPhone 12. Older chargers will still work, but they may charge at slower speeds.

However, you cannot use newer standard iPhone chargers with the iPhone 12. That’s because the iPhone 12 uses the older Lightning standard, while newer phones and cables use the newer USB-C ports. You would need an adapter.

Can You Charge an iPhone 12 From Third-Party Adapters?

Yes, you can use third-party chargers for the iPhone 12. However, I recommend using an Apple original adapter or a third-party adapter that has the MFi label. The MFi, or Made for iPhone, certification ensures that the adapter meets the necessary requirements to charge an iPhone safely.

Charging an iPhone 14 With an Apple Watch Charger: Any Differences?

No, there is no difference when using an Apple Watch charger for an iPhone 14. The Apple Watch charger cannot charge any iPhone, whether it’s the iPhone 14 or any other model. That’s because it uses a different wireless charging technology.

Conclusion

I hope this iPhone charging guide was helpful! You can’t charge an iPhone with an Apple Watch charger. They use different wireless charging technologies. Apple Watch chargers were designed to charge Apple Watches only, not iPhones.
