MagSafe is nice and preferred for my M4 Air. The 35W dual charger, while not the fastest, provides decent charge speed and the battery is very efficient so I usually only have to charge it once every 2-4 days depending on how much im using it. Thankfully my partner has a 70W USB-C for their windows laptop which I will borrow once in a while if I need to power up quick before leaving the house.
