Charger for four devices

This 140W GaN adapter powers up to four devices at once through two USB-C and two USB-A ports. It suits users who carry a laptop, phone and accessories and want a single brick for all of them.

Sustained 140W output

Each USB-C port can deliver a maximum of 140W continuously, so a 15-inch MacBook Air reaches 50% charge in 30 minutes even while other ports are active. The PD 3.1 standard negotiates the optimal voltage for every connected device without throttling.

ActiveShield 2.0 monitoring

The ActiveShield 2.0 system checks temperatures over three million times per day and adjusts power flow instantly. A built-in colour display shows real-time wattage, temperature and port status so you can verify normal operation at a glance.

Questions about this item

How hot or noisy does the 140W GaN charger get when running all day?

The ActiveShield 2.0 system monitors temperatures over three million times daily, while GaN technology runs cooler than traditional silicon adapters and has no moving parts for silent operation.

Which cables do I need to use the two 140W USB-C ports at full speed?

A 240W USB-C to USB-C cable is included; any other cable must support PD 3.1 and 140W output to reach the maximum rate.

Will the 140W charger safely fast-charge my older phone that only accepts 18W?

Yes, the PD 3.1 ports negotiate power with each device, so an 18W phone draws only what it supports while the charger remains within its safety limits.
