Introduction
---------------------------------------------------------------
ChargerLAB found Apple also listed a brand new 70W power adapter on its official website after WWDC2023. As Apple’s second GaN charger, it’s smaller than the previous 67W charger but with higher output power.
And today, we're going to take it apart to see how it differs from other Apple chargers we’ve taken apart before.
