Can I Use a 100W Charger With My Phone?

Yes, if the charger and cable use USB PD. The phone will not take more power than it requests.

USB PD is designed so the phone is in control. A 100W PD charger offers power. The phone asks for a profile it supports, often 18W, 25W, 27W, or 45W.

Use a USB-C to USB-C cable that can carry the current. A damaged or unrated cable is a bigger risk than a high-wattage PD charger.

Do not assume proprietary phone-brand names (SuperVOOC, Warp, HyperCharge, and similar) just because a charger is 100W. Those need matching hardware. Charzar lists them only when a source listing states them, and does not treat them as verified in the compatibility engine.
