Questions about this item

Does the 120W GaN charger stay cool when all four ports are used continuously?

GaN technology minimises heat generation so the charger runs cooler than traditional silicon designs even under sustained multi-port loads.

Which cables must I already have to use the two USB-C and two USB-A ports?

You need USB-C to USB-C cables for the USB-C ports and USB-A to USB-C or USB-A to Lightning cables for the USB-A ports depending on your devices.

Will the 100W single-port output charge my 96W MacBook Pro 16 at full speed alongside older 61W and 29W USB-C laptops?

Yes the charger automatically identifies each device and delivers the correct power up to 100W on one USB-C port while sharing the remaining 120W total across the other ports.
