Depends on if you need the faster charging. For me personally, I don't see any point. Battery life for me is so good I can just charge when I need to. I just use wireless charging at home, and it's slow but I'm in no rush in the evening
Apparently there's not much difference between 25w and 45w chargers. Check out YouTube reviews before buying. I myself was thinking of buying the 45w charger but after watch the reviews. I decided to save my money and stick with my old charger.
