Do I need a special cable for 100W?

Yes. The USB-C cable must be rated for the wattage you want to draw, otherwise it limits the charge rate.

Is 100W overkill for a phone?

A phone only draws what it is designed to take, so it is safe — just more charger than you need.

Will it charge a gaming laptop?

It can charge many USB-C gaming laptops, but some ship with proprietary higher-wattage chargers. Check your laptop's requirement.

100W USB-C Charger – High-Wattage Multi-Device Desk Charger

Name: 100W USB-C Charger – High-Wattage Multi-Device Desk Charger
Brand: Various

Various · Charging & Power

100W is the tier above the common 65W plug and exists for two situations: a larger laptop that will not charge at full speed on 65W, and a single charger expected to run several demanding devices at once without throttling any of them.

It is a desk charger more than a travel charger — heavier, and overkill if your only laptop is a thin-and-light. Make sure the cable can carry the power too: a 100W charger paired with a low-rated cable will charge at the cable's limit, not the charger's.
