Apple Watch needs to get charged regularly with either the Apple charging station or MFi certified power banks.
Many Apple lovers are aware that unlike other iOS devices, Apple Watch adopts Qi wireless charging technology and does not rely on Lightning cables. However, Apple Watch cannot be charged on any Qi charger, such as the no-brand ones selling on Amazon. Some researchers discover the probable reason behind this phenomenon. It turns out Apple has tweaked the Qi wireless charging standard to ensure that Apple Watch only works with officially approved Apple Watch chargers and accessories.
“The Apple Watch charger that comes with the device is Qi based, but the firm decided not to submit it for interoperability testing. I think they are using version 1.1.2 of Qi, but the software stack has been altered so that only Apple’s charger works with Watch.” John Perzow, VP of market development at the Qi consortium, told The Register.
There are also some reasonable guesses:
- Don't need to worry about possible charging issues or warranty claims due to using a random watch charger
- Want to keep a consistently satisfying user experience
