How to check if this adapter is original?

Hello Vahidhussain,

It appears this is marked as an Apple-certified charger. Is there something going on with this charger that leads you to believe that there is an issue with it, or that it may not be a certified charger? If so, what exactly is going on?

Was this adapter purchased from Apple directly or a third-party source? We want to rule out any potential 3rd party issues or cause.

Also, if there is an issue with charging your iPhone, you can look over and follow the guidance on this page: If your iPhone or iPod touch won't charge - Apple Support.
