If you're wondering whether you can use the charger from your trusty old iPad 1 to power up your shiny new iPhone XR, then you've landed in the right place! Let's delve into the compatibility of these devices and see if you can make your charging setup a bit more versatile.
First things first, the original iPad charger, that chunky 10W power adapter that accompanied your iPad 1, does have the capability to charge your iPhone XR. The iPhone XR supports fast charging, which means it can handle power input up to 18W for optimal performance. While the iPad 1 charger falls short of the fast charging capacity, it can still get the job done.
When you plug in your iPhone XR with the iPad 1 charger, you may notice that it charges a bit slower compared to using the 18W USB-C power adapter that comes with the device. The reason behind this is the power output difference between the two chargers. The iPad 1 charger delivers 10W of power, while the iPhone XR's default charger pushes out 18W. Despite this speed discrepancy, your iPhone XR will charge up just fine using the older iPad charger. It's like taking a leisurely stroll instead of a brisk walk - you'll get to your destination at a more relaxed pace.
However, there are a couple of things to keep in mind when using the iPad 1 charger for your iPhone XR. Because the iPad 1 charger predates USB Power Delivery (USB PD) technology, which optimizes power delivery for various devices, the charging process may not be as efficient. This means the iPad 1 charger might not provide the most efficient charging experience tailored for your iPhone XR when compared to a more modern charger.
In addition, using older chargers with newer devices can potentially impact the overall battery health of your iPhone XR over time. While it's perfectly safe to charge your iPhone XR with the iPad 1 charger occasionally, using it as your primary charging method may not be ideal for long-term battery longevity.
In conclusion, yes, you can use your old iPad 1 charger to juice up your iPhone XR. It may not charge as quickly as the included 18W power adapter, but it will definitely get the job done. Just remember that for optimal charging speed and efficiency, using the recommended charger for your iPhone XR is always the best choice.
