Will a 67W adapter damage Macbook Air M2 battery lifespan?

I got my Macbook Air (M2, 2022) a few months ago, and it came shipped with a standard 30W adapter. I recently received a 67W adapter instead, and it does charge my laptop quite a bit faster.


Now I'm wondering, could this be damaging to my battery? As in, the lifespan of it? Should I stick to my 30W or is the 67W fine?

MacBook Air, macOS 13.5

Nope. The battery charging algorithms are under the sole control of your Mac, and are specifically intended to maximize its useful life.
