Charger for my new iPhone 16

Best answer: It shouldn't, but neither are deemed compatible with the iPhone 16 based on what limited amount of information I can find on these two devices on the Internet.

Also, no one here can guarantee any non-Apple product can, or cannot, harm your iPhone's battery.

Finally, you can use this link to see if these devices are MFi-licensed: Mfi Licensed Accessories - Apple

The power adaptor is the only component standing between your pricey, new, low-voltage DC phone and high-voltage AC energy.

Skimping here would not seem to be a wise move.
