Can You Charge an iPhone With an iPad Charger?

Maybe you’re wondering if you can charge your iPhone with an iPad charger. 

The answer is yes, you can. All you need to do is connect your iPad USB power adapter to your iPhone and plug it into a power outlet. The speed, however, will vary on the wattage of your chapter.  

To learn more about charging your iPhone with an iPad adapter, read on below. 

How to Charge Your iPhone With an iPad Adapter 

This is quite simple. It’s just like charging your phone with its actual charger. 

To do this, you need to connect your phone to the lightning cable. Then, connect this cable with an Apple USB power adapter. You can use varying wattages for this purpose – 10W, 12W, 18W, or 20W.  

Once you have all the connections in place, the only thing you need to do is plug the adapter into a power source.  

What iPhone Models Can You Charge With an iPad Charger? 

This depends on your charger model. 

10W and 12W Chargers 

The 10W charger usually comes with the iPad 2, iPad mini (2, 3, ; 4), and iPad Air ; Air 2 models.  

The 12W charger, on the other hand, comes with the iPad 5th-7th gen, iPad mini (5th gen), iPad Air (3rd gen), and iPad Pro (9.7 to 12.9-inch screens, 1st ; 2nd gen).  

You can use both these models to charge the following iPhone models: 

  • iPhone 3G and 3Gs 
  • iPhone 4 and 4s 
  • iPhone 5, 5c, and 5s 
  • iPhone 6 and 6 plus 
  • iPhone 7 and 7 plus 
  • iPhone 8 
  • iPhone X, XR, XS Max, and XS 
  • iPhone SE (2nd Gen) 
  • iPhone 11, Pro, Pro Max 
  • iPhone 12, Mini, Pro, and ProMax 

18W and 20W Chargers 

An 18W charger is usually packaged together with the iPad Pro (11 and 12.9 inches, 2nd to 4th gen). 

The 20W adapter, on the other hand, comes with the 4th gen iPad Air and the 8th gen iPad. 

You can use any of these to fast-charge your iPhone 8 or the newer models. 

The only exception is the iPhone 12, which needs a 20W adapter (or higher) to charge faster. Using this charger, for example, can give you 50% battery capacity in as short as 30 minutes. 

How Do You Check For Your iPad Charger Model? 

If you don’t remember the model/make of your iPad, you can still check the charger type you have at hand.  

All you need to do is check the top or bottom of the adapter. You’ll see the wattage (10W, 12W, 18W, or 20W) stated there. 

Will the iPad Charger Damage My iPhone? 

No. For one, your iPhone has an intelligent charge controller installed. That said, it will only ‘draw’ the power it needs. 

So even if you’re using a high-wattage charger, you don’t have to worry about a surge damaging your phone. 

Add to that, using your iPad adapter can make the charging process faster. 

That’s because most iPhone models come with a 5W adapter. This takes about 3.5 hours to fully charge an iPhone 11 model.  

With a 10W adapter, on the other hand, you can fully charge your iPhone in 2 hours and 20 minutes.  

As expected, it’s faster to charge your phone with a 12W adapter. With this, you can get full battery life in just 1 hour 40 minutes.  

It takes about 1 hour 20 minutes to fully charge your iPhone with an 18W adapter. 

The 20W adapter, with its high wattage, is the fastest option for your iPhone. This can fully charge your device in an hour.  

Can You Use an iPhone Adapter to Charge Your iPad? 

Yes, you can do the complete opposite – which is to charge your iPad with an iPhone charger. 

The caveat here, however, is that you can expect a slower charging time. After all, the iPhone charger is designed to power up a device smaller than the iPad.  

Normally, it usually takes 5-7 hours to charge an iPad with a 10W adapter. So if you decide to use your phone’s 5W adapter, you can expect to charge your iPad for a much longer time.  

As with the iPhone, you can charge your iPad faster by using higher-wattage adapters. So if you have one lying around for your iPhone, you can use it for your iPad as well.  

For example, you can use your 18W adapter to fully your iPad in 2.15 to 2.67 hours.  

A 20W adapter, on the other hand, only requires 1 hour and 20 minutes to get your iPad battery to 100%.  

If you don’t have an iPhone charger lying around, you’ll be glad to know that you can use your iPad adapter to juice up your phone. 

And, depending on the wattage of your iPad adapter, you can charge your phone at a faster rate.
