Anker 65W vs 100W for MacBook Air: which GaN brick
Short answer: Get the Anker 735 (65W) for Air plus phone. Step up to the Anker 736 (100W) when you often charge Air and iPad hard at the same time, or want spare headroom for travel.

Both are GaNPrime bricks with foldable prongs. The 735 has two USB-C ports plus USB-A. The 736 pushes more total watts when two hungry devices share the brick. A 65W charger is still fine for a MacBook Air alone. Shared total wattage is the usual reason to buy 100W.
