Samsung Galaxy Book USB-C charger wattage

Modern Samsung Galaxy Book Pro / 360 classes publish a 65W USB Type-C inbox adapter (Book3 Pro, Book4 Pro, Book5 Pro / Book5 360 on Samsung US). Galaxy Book4 Ultra uses 140W Super Fast Charging. Match the wattage on your lost cube, then shop a nearby 65W or 140W USB-C PD / GaN brick. Older Galaxy Book S listed a 25W USB-C charger. These Windows Galaxy Book classes are distinct from Chrome OS Samsung Chromebook USB-C and from Acer Chromebook USB-C pages.

Official Samsung US support, Samsung US product / B2B spec sheets, and Samsung US news specs list the wattage and connector for each Galaxy Book class (accessed 21 Sep 2026). Confirm the wattage printed on your brick or in your Galaxy Book setup guide before you replace it. Full method: how to pick.
