Hey there, and welcome to Apple Support Communities yashi25,

We can certainly understand your concern and can help provide some insight.

We recommend checking out these steps for more information on how to identify an adapter.

" 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.
