The other day, my dad and I got to talking about power adapters and how Apple guards against having some 3rd party adapters not work with their equipment.
Then, it got me to thinking about how many other people do not know (but should) about those power adapters and what you should and should not do with them. Â After a quick Google search, I came across this page to help me explain (and learn) about these adapters so I can know how these work and take care of them even better than before.
Apple offers different adapters for their hardware - from iPods, to iPhones, all the way up to the Mac Pro. Â Here's a copy of the official page that talks about these adapters and how they actually work.
About Apple USB power adapters
This overview will help you identify a USB power adapter from Apple. Apple USB power adapters and cables are included with many products and are available separately from Apple and authorized Apple resellers.
Customer safety is a top priority at Apple. That’s why all our products—including USB power adapters—undergo rigorous testing for safety and reliability and are designed to meet government safety standardsaround the world.
As part of our efforts to reach our environmental goals, iPhone models no longer include a power adapter in the box. iPhone continues to work with existing power adapters and USB-A to Lightning cables, such as those included in prior models. iPhone models now include in the box a newer USB‑C to Lightning cable that supports fast charging and is compatible with USB‑C power adapters and computer ports that you might already have. You can use either a USB-A to Lightning cable or the newer USB-C to Lightning cable with your iPhone.
You can use any of the adapters listed below to charge your iPhone, iPad, Apple Watch, or iPod. You can also use a Mac USB-C Power Adapter or third-party adapters that comply with applicable safety standards. For more information about charging your iPhone, iPad, Apple Watch, or iPod, refer to the Safety, Handling, and Support section of the iPhone User Guide, iPad User Guide, Apple Watch User Guide, or iPod User Guide.

Learn about USB power adapter certifications
When an iOS or iPadOS device comes with an Apple USB power adapter, that adapter is certified to meet government safety standards in countries and regions where the device is available. Many of these countries and regions, including the United States, have adopted the Safety of Information Technology Equipment standard, IEC/UL 60950-1.
Apple USB power adapters are designed for use with power sources rated to provide 100V AC to 240V AC at 50Hz to 60Hz. The Type A (flat parallel-blade design) Apple 5W USB, 18W, and 20W USB-C power adapters, as well as the 10W and 12W USB power adapters (with Type A AC plug attached) also comply with the IEC/UL 60950-1 and IEC/UL 62368-1 standards for use with power sources rated to provide 115V AC at 400Hz.
