nimble 3 in 1 wireless charger sold by apple.com not working

Apple’s right in that you are beyond the return period of 14 days, but you are still within the 1 Year Limited Manufacturers Warranty which covers defects in material and parts. Take it to your nearest Apple Store Genius Bar or Apple Authorized Service Provider and have them evaluate it. But if Apple has already determined they won’t cover it, unfortunately there’s your answer. They had reason to believe it wasn’t a defect but wear and tear by you.

Was the charger an Apple branded product? If yes, Apple is responsible for handling the warranty on the device.

If the charger was manufactured by another company, and Apple simply sold the product online or in an Apple Store, then the company that manufactured the product is responsible for service and support of the product.

What is the make and model number of the charger that you purchased?
