118W GaN USB-C adapter with 6.6ft cable

This GaN charger delivers up to 118W of power through a single USB-C port. It supports PD 3.0 profiles including 29W, 30W, 61W, 67W, 70W, 87W and 96W. The 6.6ft USB-C to USB-C cable is included in the box. It targets users who want one compact brick for laptops, tablets and phones.

PD 3.0 limits and automatic negotiation

The adapter negotiates the highest common PD profile with the connected device. It will not exceed the device's maximum input rating, so a phone capped at 20W will only draw 20W. The charger cannot supply proprietary fast-charge standards that sit outside the USB PD specification. Multi-port charging is not supported because only one USB-C output is present.

Capacity headroom for laptops and phones

At 118W the unit can fully charge most compatible laptops in roughly one hour twenty minutes. Phones typically reach 80% in about twenty minutes. The 98% conversion efficiency keeps heat low during sustained loads. It is not suited for devices that require more than 118W or for users who need to charge two laptops simultaneously.

Questions about this item

Should I pick the 118W GaN charger for my MacBook Pro M3 or a lower-wattage model?

The 118W unit covers every PD profile listed — 29W, 30W, 61W, 67W, 70W, 87W and 96W — so it will fast-charge a MacBook Pro M3 at full speed and still negotiate safely with an iPad Air 10.9 or a Galaxy phone.

What does the 118W rating actually deliver when I plug in a MacBook Pro 12.9?

It supplies up to 118W over USB-C PD 3.0, enough to fully charge most laptops in roughly 1 hour 20 minutes and push a phone from 0% to 80% in about 20 minutes.

Which USB-C standard does this adapter use and what power ceiling does it enforce?

It uses USB Power Delivery 3.0, which negotiates up to 118W; the charger will never exceed the device's own PD limit, so a 96W MacBook draws 96W, a 67W model draws 67W, and so on.
