I went to a local electronics store and bought a MagSafe charger. It's the model number A2140. Then I remembered this article...
9to5mac.com
...which says that there's a newer model with the number A2548 from September 2021.
I don't think the one I bought was laying around in that store for 1,5 years. So I wonder what's going on here.
They're a little date printed on the labels of Apple boxes lately, which looks like 01/2022 or 07/2023. Is this the manufacturing date? If so, my charger was made in 08/2022 but still has the model number A2140. Is the A2548 just for the US (I'm in Europe)? My charger came with a firmware version pre-installed which got released in December 2021, according to MacRumors, which was still the current version in 08/2022.
