When using Anker chargers like GaNPrime chargers to charge Macbook Pro or Macbook Air, we may find there is a "plug" logo(see below) rather than a normal charging logo.

This is Apple's strategy for identifying third-party chargers. Due to MacBook charging identification, it's normal to see a plug symbol in the battery icon when charging a MacBook with a third-party wall charger. Charging will revert to normal automatically after around one minute. This prompt will appear every time as long as it is plugged in and charged.
