I want to check if my charger is original

We literally get hundreds of these types of posts. If you did a search, you would know that there is no way anyone here can tell if what you have is an original Apple product or a fake by either a picture and/or serial number.

The bottom line? If you purchased it directly from Apple or an Apple Authorized Reseller, then it is an original Apple product; if not, then it could be a fake.
