Quick answers
Is it safe to charge the Galaxy S25+ with the Google 30W USB-C?
Yes. USB Power Delivery negotiates power, so the Galaxy S25+ only takes what it can handle and the charger only gives what it can supply. A weaker charger is slower, not dangerous.
How many watts does the Galaxy S25+ need for fast charging?
45 W or more, from a USB-C PD charger that supports PPS. Super Fast Charging 2.0 (45W) works with the bundled 3A cable and a 45W PPS charger.
How long does the Galaxy S25+ take to charge with the Google 30W USB-C?
About 26 min to 50% and 1 h 15 min to full, estimated with the device idle.
