Will this charge my Galaxy phone at 45W?

Only Galaxy phones that support Super Fast Charging 2.0, such as the S20 Ultra and later S and Note models, reach 45W. Older or mid-range Galaxy phones cap at 25W or lower.

Does the box include a cable?

Yes. It ships with a USB-C to USB-C cable rated for 5A, which is what the adapter needs to deliver full power.

Can it charge a laptop?

It will charge USB-C laptops that accept 45W or less, but many laptops want 65W or more and will charge slowly or only while idle.

Is it compatible with iPhone and other USB-C devices?

It follows the USB PD standard, so it charges iPhones and other USB-C devices at their supported rate, though only Samsung devices get the PPS fast-charge profile.

Can I charge two devices at once?

No. There is a single USB-C port, so you need a multi-port charger or a second adapter for a phone and earbuds together.

Is it worth it over a cheaper third-party charger?

If you want guaranteed PPS support and the included 5A cable, the official adapter removes guesswork. A reputable third-party 45W PPS charger can match the speed for less but may not include a cable.
