Yes any charger 15w/25w/35w/45w will work and determine the speed it charges atAll you with the fancy schmancy 45w chargers and I'm going to buck the trend and use this 35w charger that I got when I got my ZF3. I never opened this so I hope it works.
This is a stupid question, but this WILL work with the S22 Ultra right? I mean, it'll be faster than 25w but not as fast as 45w? That said, 25w has been plenty enough for me but this is just otherwise catching dust. lol
