- Will it fast-charge a Galaxy S24 Ultra at full speed?
- Yes, if the phone is set to Super Fast Charging and the bundled cable is used. The S24 Ultra accepts 45W, which is what this adapter is rated for.
- Does it work with older Galaxy phones?
- It charges Galaxy S20, S21, S22, S23 and Note 10/20 series phones. Older or lower-rated models will charge at their own maximum, not at 45W.
- What is in the box?
- The 45W USB-C wall adapter and a 6-foot USB-C to USB-C charging cable. No wall plug adapter for other regions and no headphones.
- Can it charge a laptop or tablet?
- It can charge USB-C devices that accept up to 45W, including many tablets and thin laptops. Heavier laptops that need 65W or more will charge slowly or not at all.
- Is a 45W charger safe for my phone?
- Yes. USB-C charging negotiates the rate the phone asks for, so a lower-rated phone draws only what it supports.
- How does it compare with Samsung's own 45W charger?
- Same wattage and the same Super Fast Charging standard, and this one includes a cable. Samsung's first-party unit has a longer reputation for build and safety certification.
