  • Three ports share 140 W total with smart 65 W, 45 W, 18 W allocation

High-power GaN charger for laptops

This 140W USB-C GaN charger delivers up to 140W from either USB-C port, reaching 55% battery on a MacBook 16 Pro in 30 minutes. It suits professionals and students who need fast, single-brick power for USB-C laptops, tablets and phones. Buyers who require more than 140W total output or legacy barrel connectors should look elsewhere.

Touch LCD and smart three-port distribution

The built-in LCD shows real-time power per port and turns off automatically after one minute of inactivity; a touch button wakes it. When all three ports are used — two USB-C and one USB-A — the charger allocates 65W, 45W and 18W simultaneously. Users who want per-port current or voltage readings will not get them from this display.

Simple wall installation

Plug the unit into a mains socket and connect devices; no driver or software setup is required. The LCD enters sleep mode after one minute without activity, so a dark room stays dark. Builders who need a detachable mains cable or a desktop-style form factor will find this fixed-prong wall unit unsuitable.
