A 65W GaN fast wall charger is most noticeable on devices that can accept higher USB-C Power Delivery (PD) wattage or that need extra headroom while you’re using them. A 20W charger is fine for basic phone charging, but it can struggle with larger batteries, laptops, and multi-device setups.
Many modern laptops (especially thin-and-light models) charge over USB-C at 45W, 60W, or 65W. With a 20W charger, a laptop may charge extremely slowly, refuse to charge, or even lose battery during use. A 65W GaN charger can typically power the laptop and recharge the battery at the same time, making it far more practical for travel and desk use.
Higher-end tablets can draw well above 20W during fast charging, particularly larger models. A 65W charger can shorten top-ups and is better at keeping the tablet stable during heavy tasks like video editing, gaming, or video calls while plugged in.
Some Android phones can charge at 25W, 45W, or higher with compatible PD/PPS chargers. A 65W charger won’t force extra power if the phone can’t use it, but it provides the capability needed for faster charging on devices that can.
Devices like the Nintendo Switch and certain handheld gaming PCs often benefit from a higher-watt USB-C PD source to maintain performance while charging. A 65W charger also adds flexibility for powering hubs, external SSD enclosures, and other USB-C accessories that can be picky about power.

No. USB-C PD devices negotiate power, so the phone will only draw what it supports; the charger’s higher wattage is just available capacity.
